Description

  The present invention relates to a receipt definition data creation device and a program thereof, and more particularly, when managing necessary data from receipt data read by character recognition in order to manage sales of a plurality of stores such as a shopping mall. The present invention relates to a technology that supports creation of necessary definition data.

  The tenant management department that manages stores of tenants (such as companies that operate stores) that open stores in shopping centers, shopping malls, etc. collects daily sales for each store, and breakdowns of sales such as cash sales, coupon sales, etc. ( Sales management item). When creating the sales breakdown, payment receipts provided from each store are collected and the numerical value of the sales management item is calculated. However, since the format of the payment receipt provided from each store depends on the POS system installed in each store, it is currently created in various formats. Therefore, the payment receipt processed by the tenant management department has a wide variety of items, item names, print sizes, print fonts, and the like.

  For example, regarding the names of the items on the payment receipt, even though the total sales, total sales, total sales, total sales, etc. indicate the same contents, different names are printed depending on the POS system. In addition, since the tenant's store that opens a store is frequently replaced, a new payment receipt format must also be supported. For this reason, the tenant management department requires a great deal of labor for the sales totaling work for totaling the payment receipts as unified sales management data, and the human and time burden for that is very expensive. It is.

  Note that Patent Document 1 discloses a receipt processing apparatus. In this receipt processing apparatus, text data is generated by recognizing characters from the receipt image, a predetermined character string is selected from the text data, and a line position including the selected predetermined character string is detected. Then, line data in units of lines is sequentially selected from a predetermined line range on the text data determined based on the detected line position, and data relating to the item is extracted from the line data.

  Patent Document 2 discloses a technique for automatically creating a form definition for any form including an indefinite form without a ruled line without manual intervention. In this technique, a receipt is read as an image, a stamped item is cut out as a table area, x-coordinate and y-coordinate are calculated for each table area, and a frequency distribution table of x-coordinate is created. Then, the form definition is created by determining the alignment and determining the product field, the number field, and the price field.

JP 2004-164218 A JP 2006-178802 A

  In the tenant management department of a company (organization) that operates a shopping center or the like, the clerk has traditionally used to collect the payment receipts (hereinafter referred to as receipts) provided by each store such as a shopping center. The receipt was read visually, and the read data was manually input to the data processing device. The work amount of the sales totaling work is very heavy because the number of stores may reach 100 stores or more and must be performed every day.

  As a proposal for reducing this burden, it is conceivable to automatically collect sales data (receipt data) of each store from a terminal of each store via a network. However, in general, each store has a different business entity, so it is necessary to obtain permission to open the network individually, and the type of network to be connected and the difficulty of adding / modifying applications differ depending on the installed system. There are difficult problems.

  Another way to reduce the above-mentioned work load by changing the existing system, especially information devices such as terminals in each store as much as possible, is to recognize character images instead of reading receipt data by humans. The reading method can be considered. That is, the receipt of each store is read by, for example, a reader or scanner having an OCR (Optical Character Recognition) function, and the necessary receipt items and their numerical data are extracted as sales management items, and the sales management data is extracted. This is a method to re-enter.

  In this way, when recognizing a character image of a receipt and automatically creating sales management data, correspondence information on how sales management items required as sales management data correspond to read items of receipts, In addition, it is necessary to prepare in advance the receipt definition data as the character string (item name) of the read item of the receipt and the position information on the image of the amount column corresponding to the read item.

  Once this receipt definition data is created and registered in the receipt recognition device, the receipt image is read by a reading device or the like having an OCR function, and the receipt items necessary for creating sales management data are extracted from the read receipt image. , It is thought that daily sales management data can be collected to some extent automatically.

  The problem is how to create this receipt definition data. First, it is conceivable to manually input the receipt definition data one by one. However, in a large-scale shopping mall or the like, the number of stores may be more than 100, and the receipt definition data is manually input. This is a huge amount of work. Furthermore, in a shopping mall or the like, stores that are opened frequently are frequently replaced, and it is troublesome to manually input new receipt definition data every time a new store joins.

  Therefore, a computer-aided technology capable of creating receipt definition data as easily as possible is desired. However, the technology for automatically creating a form definition from the receipt image of Patent Document 2 is a case that is covered by the present invention. Is insufficient and cannot be used for the following reasons.

  (1) In Patent Document 2, sales management data including a specific group of sales management items common to sales management of each store required by the tenant department is not considered at all.

  (2) Also, with the technology of Patent Document 2, it is possible to create item definition information for each receipt, but all items printed on the receipt are targeted, and only the necessary items must be selected. I can't.

  (3) In addition, the sales management items particularly required by the tenant management department do not always match the item names of the receipt items printed on the receipts of each store, and the sales management items and the receipt items are not necessarily It does not necessarily correspond one-on-one.

  FIG. 27 is a diagram illustrating an example of a correspondence relationship between sales management items and receipt items.

  For example, as shown in FIG. 27A, the sales management items required by the tenant management department are “cash sales”, “payment sales”, “credit sales”,. It is a unified item common to stores. In the receipt shown in FIG. 27B, the “cash sales amount” on the 14th line corresponds to the first sales management item “cash sales”, and the second sales management item “overtime sales”. There is no receipt item corresponding to, and the “other voucher amount” on the 18th line corresponds to the third sales management item “credit sales”.

  On the other hand, although not shown in the drawings, in the receipt of another store, for example, the sum of the receipt item “cash amount on daily report” and the receipt item “thank you card” is the first sales management item “cash sales”. The receipt item “Daily Overtime Sales” corresponds to the second sales management item “Overhead Sales”, and so on, the correspondence between each sales management item and the receipt item is Every store is completely different.

  In view of such a background, an object of the present invention is to provide means for easily creating receipt definition data for collecting sales management data by recognition of a receipt. That is, the present invention reads receipts of different formats output from a plurality of stores such as shopping malls, and easily and efficiently creates receipt definition data for acquiring only necessary sales management items accurately and efficiently. It aims to provide a means.

The outline of the present invention for solving the above problems is as follows. In the following, a case where a sales management item is used as a specific basic management item common to each store collected from a receipt will be described as an example.
(1) A receipt issued by a store that is a creation target of receipt definition data for collecting sales management data is read as an image, displayed on a screen, and receipt definition data is created by screen operation.
(2) At this time, the necessary necessary sales management items (also referred to as checkout items) are displayed on the screen, and the corresponding read items (also referred to as receipt items) on the receipt image data are displayed for each item. The selection is made by a point operation or a drag operation using an input device such as the above, and the position information is acquired to generate receipt definition data. When dragging with a mouse or the like, it is not necessary to be exact, and it may be anywhere on the corresponding item. For example, the system determines the dragged position and automatically displays a frame line surrounding the selected item so that the operator can confirm that it has been correctly specified.
(3) Since the selected item is displayed as a read item, the operator can work while confirming.
(4) The selected reading item can be operated with other reading items by specifying four arithmetic operations, for example. When an arithmetic expression is specified, the arithmetic expression is set in the receipt definition data, whereby a plurality of read items can be associated with one sales management item.
(5) Also, the presence of an item having the same name as the selected item is checked in the receipt. When there are a plurality of items having the same name, the user is prompted to set a plurality of keywords and marker items (items that determine the criteria for the necessary item positions) to be specified as read items.
(6) Also, when the read item is assumed to be difficult to recognize OCR (character collapse, character contact, ruled line contact, etc.), a receipt item that replaces the read item is defined as a substitute item, and the relative position from the substitute item To recognize the amount of money.
(7) Also, for example, by referring to store information, when there is already receipt definition data for a similar job, it is possible to create new receipt definition data using the existing receipt definition data. .

Specifically, the present invention obtains information on receipt items that may be different for each store printed on a receipt and information on the amount corresponding to the receipt item by recognizing images of receipts issued by a plurality of stores. Based on the acquired information, a receipt recognition system that collects basic management data including specific basic management items common to each store and information on the amount corresponding to the basic management items is used to recognize receipts for each store. A receipt definition data creation device for creating receipt definition data to be used, the image data storage means for storing image data including image data of a receipt issued by a store for which receipt definition data is to be created, and the predetermined data Basic data storage means for storing information on basic management items, and basic management stored in the basic data storage means The definition input screen displaying means for displaying the definition input screen including the display of the eye information and display the image data of the image data storage means stored in the receipt, the operator in the image data displayed on the definition input screen Input data processing that accepts input of the receipt item selected in the item and the position of the amount of money corresponding to the receipt item, and accepts input of correspondence information between the receipt item and the basic management item displayed on the definition input screen And the information received by the input data processing means, the receipt item, the position of the amount corresponding to the receipt item in the image data, and the correspondence information between the receipt item and the basic management item Definition data creation means for creating receipt definition data including the receipt definition data created Characterized in that it comprises a definition data storing means for storing.

In the aspect of the invention, the definition input screen further includes an arithmetic expression input area for allowing an operator to input an arithmetic expression for the receipt item, and the input data processing means includes the definition According to another aspect of the present invention, there is provided means for creating correspondence information for associating one or a plurality of the receipt items with the one basic management item according to the arithmetic expression of the receipt item input in the arithmetic expression input area of the input screen. .

Further, in another aspect of the present invention, the input data processing means, whether other receipt items of the receipt item having the same name in the receipt of the image data to be displayed on the definition input screen is present If there is a plurality of receipt items including receipt items with other names, or other receipt items with unique names in the receipt, to identify the position of the receipt item to be associated with the basic management item , if present the has a means for input through the definition input screen, the definition data generating means, a plurality including a receipt item of the basic management for specifying the position of the receipt items to associate the item, other names to create a receipt definition data including information other receipt items unique name in the receipt item or the receipt of It characterized by having a stage.

In another aspect of the present invention, the input data processing means designates a receipt item or a position of an amount corresponding to the receipt item in the receipt image data displayed on the definition input screen. Accepts the operation input, determines the area where the character string of the corresponding receipt item in the image data is printed or the area where the character string of the amount is printed, and displays the frame surrounding the area or the character string in the area It is characterized by having means for highlighting .

In another aspect of the present invention, the image data storage means further includes information on character recognition accuracy as a result of recognizing a character printed on a receipt issued by a store to which the receipt definition data is to be created. And the input data processing means prompts an operator to specify an alternative item to substitute for the receipt item when the character recognition accuracy for the character of the input receipt item is less than a predetermined value. outputs, and means for accepting an input of alternate items that operator specified, the definition data creation means, and the said substitute item information in addition to the receipt item, the position of the amount corresponding to the receipt item The image forming apparatus includes means for creating receipt definition data including information indicated by a relative distance from the substitute item in the image data .

In another aspect of the present invention, the input data processing means displays the created receipt definition data or data extracted from the history data on the definition input screen, and stores other receipt definition data. It has a means to make an operator refer at the time of creation.

The receipt definition data created as described above includes the following data.
(1) Correspondence information between basic management items and read items in receipts. That is, information indicating which reading item in the receipt the amount to be recorded as a basic management item.
(2) The relative position information of the character string of the reading item in the receipt and the corresponding money amount column.
(3) Information indicating an arithmetic expression when the amount of the basic management item is calculated by four arithmetic operations of the amounts of the plurality of reading items.
(4) In addition, when there are multiple items with the same name (same character string) as the required reading items in the receipt, character information and reading characters such as multiple keywords and marker items for specifying the required reading items Information indicating the positional relationship with

The effects of the present invention are as follows.
(1) When reading items necessary for basic management items are extracted from receipts, receipt definition data indicating which basic management items correspond to which reading items can be easily created using actual receipts. . In particular, the operator can easily perform an input operation while preventing an input error while checking the selected reading item on the screen.
(2) Since the calculation formula of the reading item can be set in the receipt definition data, the amount of one basic management item can be calculated from the amounts corresponding to a plurality of reading items. Even if it differs from store to store, data on unified basic management items can be collected.
(3) When there are a plurality of reading items necessary for the basic management item from the receipt, the item names that become a plurality of keywords for specifying the reading item to be selected and the positional relationship with the reading item are indicated. Information of marker items having other unique item names to be identified can be set in the receipt definition data. As a result, it is possible to avoid erroneous recognition of receipt data extraction when collecting basic management data.
(4) Reading items corresponding to basic management items can be selected on the screen with a simple operation, and it has an automatic adjustment function for the specified area, making it easy to input and confirm. You can often create receipt definition data.
(5) In addition, even if there is a case where OCR recognition is difficult for the read item due to character crushing, character contact, ruled line contact, etc. in printing the receipt, other items in the receipt can be defined as substitute items for the read item. , Receipt definition data with high reading accuracy can be created.
(6) In addition, when creating new receipt definition data for a store with the same business content, the receipt definition data can be created by inputting only the portions of different reading items by diverting the existing receipt definition data. Therefore, receipt definition data can be created quickly.

  By using the receipt definition data created by the present invention, basic data required by the tenant's management department is uniformly collected from receipt data of various stores with different receipt reading items, and a sales management database, etc. Can be saved in the basic data management database.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following, an example of an apparatus for totalizing store sales will be described. However, the present invention is not limited to sales totalization, and totals actual data printed on purchase total data or other slips. The present invention can be applied to a device for the same.

  FIG. 1 shows an apparatus configuration example for explaining the outline of the present invention. In FIG. 1, reference numeral 1 is a CPU and a storage device such as a hard disk or memory, etc., and a receipt definition data creation device that executes processing for creating receipt definition data based on image data read from a receipt, and 2 is a receipt. A receipt for which definition data is to be created, 3 is a display device, and 4 is an input device such as a keyboard or a mouse.

  The receipt 2 is read by the reader 10 while being sandwiched between transparent carrier sheets and the like. The reader 10 is a device that reads an image on the receipt 2 by scanning an image using an optical method or the like. The image data reading unit 11 has a known OCR processing function and converts an image read by the reader 10 into predetermined image data. When the reader 10 has an OCR processing function, the image data reading unit 11 may not have an OCR processing function. The image data includes, for example, an image file in which image data is stored and character data recognized by OCR. The image data reading unit 11 stores the image data of the OCR processing result in the image data storage unit 101.

  The definition input screen display unit 12 refers to the store master 103, and generates basic sales management item information and images stored in the basic data storage unit 102 in order to create receipt definition data for the specified store. A definition input screen having an image data display area including receipt image data stored in the data storage unit 101 is displayed on the display device 3.

  The input data processing unit 13 inputs the receipt reading item, the position information of the amount column corresponding to the reading item in the image data, and the correspondence information between the reading item and the sales management item from the displayed definition input screen. . For this reason, the input data processing unit 13 obtains the coordinates of the position of the reading item in the image data and the coordinates of the position of the corresponding money amount column from the input device 4, and manages a plurality of reading items as one sales management. An operation definition unit 132 that defines an operation expression associated with an item is provided.

  The input data processing unit 13 also sets a plurality of keywords that are set by inputting, from the definition input screen, a plurality of keywords that serve as a reference for specifying the reading item when another item having the same name as the reading item exists in the receipt. And a marker item setting unit 134 for determining other unique reading items as a reference for specifying the reading unit 133 and the reading items. Further, the input data processing unit 13 causes the operator to designate another receipt item to be substituted for the read item as a substitute item when the input read item has a recognition error or the character recognition accuracy is poor. The alternative item processing unit 135 is input.

  The definition data creation unit 14 creates receipt definition data for each store based on the information input by the input data processing unit 13 and stores the receipt definition data in the definition data storage unit 104. A specific example of the receipt definition data to be created will be described later. The receipt definition data includes information such as the item name in the read item of the receipt and the relative position of the corresponding monetary item (the position of the relative monetary column) and the correspondence information with the sales management item.

  The history data creation unit 15 creates history data of the receipt definition data created by the definition data creation unit 14 and stores it in the history data storage unit 105. This history data can be used by referring to the receipt definition data of other similar receipts.

  FIG. 2 is a flowchart showing an outline of processing of the receipt definition data creation device 1 shown in FIG.

  In step S <b> 11, the image data reading unit 11 reads the payment receipt by the reader 10. The payment receipt is total data of sales information for one day at each store, and the receipt item varies depending on the POS system used by each store. The image data reading unit 11 stores in the image data storage unit 101 the item details obtained by character recognition and the data of the entire image of the receipt.

  In step S <b> 12, the definition input screen display unit 12 creates a definition input screen from the data of the image data storage unit 101, the basic data storage unit 102, and the store master 103 and displays it on the display device 3. The entire image of the receipt is also displayed on the definition input screen.

  In step S13, the input data processing unit 13 sets a reading item, an arithmetic expression, and the like for the item of the payment receipt by inputting from the definition input screen, and the correspondence between the reading item and the sales management item, the reading item and its item The positional relationship of the amount column corresponding to the reading item is determined.

  In step S 14, the definition data creation unit 14 creates receipt definition data based on the information input by the input data processing unit 13 and stores it in the definition data storage unit 104.

  In step S <b> 15, the history data creation unit 15 creates history data for the created receipt definition data and stores it in the history data storage unit 105.

  The rough processing executed by the receipt definition data creation device 1 has been described above. Specific processing contents and data structure will be described in detail below.

  FIG. 3 is a diagram illustrating an example of the receipt 2 read by the reader 10. When the reader 10 reads the receipt 2 as shown in FIG. 3, character recognition is performed by analyzing the image by the OCR processing of the reader 10 or the image data reading unit 11. In this character recognition, each recognized character candidate constituting the character string and its position for each series of character strings, such as character strings # 1, # 2,..., # 14,. Information is extracted as image data and stored in the image data storage unit 101.

  FIG. 4 is a diagram illustrating an example of image data stored in the image data storage unit 101. As shown in FIG. 4A, the image data storage unit 101 stores data relating to the image data of the receipt image, and data of the character recognition result of the receipt (hereinafter, recognized character data) as shown in FIG. Are stored.

  As the image data of the receipt image, for example, the image image of the rectangular area of the entire receipt or the entire portion of the receipt printed with characters is stored as a bitmap image file, and the store that identifies the store that issued this receipt 2 A code is given. This store code may be input in advance from the input device 4, or a two-dimensional identification for each store given to a receipt sandwiching sheet (carrier sheet) when the receipt 2 is read by the reader 10. The code or the like may be analyzed and input.

  In the recognized character data shown in FIG. 4B, the result of character recognition for a series of character strings #n (n = 1, 2,...) Is stored, the contents of which are character string # 14 shown in FIG. An example will be described. First, the character string # 14 is the 14th character string in the receipt 2, and the identification number indicates it. The number of characters in the character string # 14 is 3 (the first candidate is “total sales”), and the coordinates of the character string # 14 are (x, y) − (x ′, y ′). This coordinate is a coordinate whose origin is the predetermined reference position of the image of the receipt 2 (for example, the upper left corner of the receipt image or the upper left corner of the rectangular area surrounding the character string group).

  Further, the recognized character data has coordinate information for each of the three characters # 141, # 142, and # 143 constituting the character string # 14. In addition, some characters of the recognition result are stored together with the degree of difference in ascending order of the degree of difference between the recognition result character and the recognition dictionary. For example, the first candidate of the recognition result of the character # 141 is “total” (difference = 1311), the second candidate is “brittle” (difference = 1581), and the third candidate is “聡 ”(difference = 1640).

  Here, the image data reading unit 11 does not store all of these recognition result candidates in the image data storage unit 101, but each character combination of the recognition candidates constituting each character string #n and all stores. This is a recognition result word dictionary prepared in advance in common, and by narrowing down the recognition result character string by collating with words in the dictionary where the character string that may be printed on the receipt is stored in advance, Only the narrowed result may be stored in the image data storage unit 101.

  FIG. 5 is a diagram illustrating an example of a basic table stored in the basic data storage unit 102. This basic table stores information on sales management items that are aggregated by the tenant management department. Specifically, in the case of managing sales management data in a shopping center, information on a shopping center code for identifying the shopping center, the name and location of the shopping center, and the number of stores in the shopping center is stored. In addition, the item name of each sales management item necessary for tenant management is stored.

  In this example, there are eight items as sales management items, and the names of these items are “cash sales”, “payment sales”, “credit sales”, “gift certificate”, “total sales”, “consumption tax” ”,“ Other deductions ”and“ Net sales ”. This system enables receipt definition data for automatically extracting information on these sales management items from various receipt items that differ for each store to be created with a simple operation. It is an object.

  In this basic table, a lower limit value and an upper limit value that can be taken by the calculation management item are determined and stored for each calculation management item. The lower limit value and the upper limit value are used for checking to reduce erroneous recognition and erroneous input when the amount of the sales management item is automatically extracted from the receipt by character recognition of the receipt image.

  FIG. 6 is a diagram illustrating an example of the store master 103. The store master 103 is a table that stores information on individual stores that issue receipts, and is prepared in advance. The store code which is the first setting item is a number for identifying the store. The second store name is the name of the store. The third business type code is a code representing the business type of the store. The fourth industry name is the name of the industry. Subsequently, as the POS system information 1, 2 and 3, the identification code of the installed POS system (example: F001), the manufacturer of the POS system (example: AAAAA), the date of introduction of the POS system (example: 2000) Such as January 1st) is stored. Further, as the payment receipt information 1, 2, 3 and 4, the length of the payment receipt, the reading format, the number of print items in the payment receipt, and other necessary information are sequentially stored. In the reading format column, the value is “0” when the reader 10 reads the receipt 2 as it is, and the value is “1” when the receipt 2 is cut into a plurality of pieces because the receipt 2 is too long. Is set.

  This system creates receipt definition data based on the data stored in the image data storage unit 101, basic data storage unit 102, and store master 103 described above. The store master 103 is not essential when the store information is known or is input in advance from the input device 4.

  FIG. 7 shows an example of the most basic data as receipt definition data. The store code is a store identification code indicating which store has the receipt definition data. Subsequently, receipt item information read from the receipt is stored for each item. The reading item 1 identification code is an identification code of the first reading item 1, and is a code for uniquely identifying the reading item in the receipt definition data.

  In the item attribute, the attribute of the read item is set. If there is no reading item with the same name (the same reading character) in the receipt, the attribute value = 1. When there is a reading item with the same name in the receipt, the attribute value = 2 when the reading item is specified based on the marker item. When there is a reading item with the same name in the receipt, when specifying the reading item based on a plurality of keywords, attribute value = 3. When it is difficult to recognize the read character and an alternative item is set, attribute value = 4.

  The receipt definition data in FIG. 7A is an example when there are not a plurality of read items with the same name, and the attribute value of the item attribute is 1. The read character 1 of the first read item is “total sales” in this example. The relative reading position 1 in the amount column indicates in which position the character string of the amount corresponding to “total sales” is printed in a relative position from the position of the character string “total sales”. Here, the relative position is, for example, the coordinates of the position of the amount column when the upper left corner of the character string area of “total sales” is the origin. The position of the amount column is indicated by the relative position from the position of the read character 1 because the number of lines actually printed on the receipt differs depending on the day even if the receipt is the same, and the position of the read character 1 is variable. It is.

  Similarly, for the reading character 2 of the second reading item “other amount of cash voucher” and the reading character 3 of the third reading item 3 “cash sales”, the identification code, the item attribute, the reading character, the data of the relative reading position of the amount column Is stored as receipt definition data.

  The receipt definition data in FIG. 7B is an example when it is difficult to recognize the characters of the read item, and the attribute value of the item attribute is 4. In this case, an item that replaces recognition of a reading item (for example, consumption tax) is defined as an alternative item (for example, a subtotal), and a relative distance from the alternative item is set as a relative reading position in the amount column.

  FIG. 8 shows an example of receipt definition data when there are a plurality of identical names in the receipt as read items. 8A shows an example when the attribute value of the item attribute is 2, and FIG. 8B shows an example when the attribute value of the item attribute is 3.

  When there are multiple items with the same read item name in the receipt (for example, the item name of the read item is "consumption tax" and the term "consumption tax" is printed on multiple lines) Is required to specify whether to extract the amount of money as a sales management item.

  If the attribute value of the item attribute is 2, define one of the items with the same name as the actual reading item by defining another unique item name that serves as a reference for specifying the position of the reading item as a marker item To do. In the example of FIG. 8A, “total sales” is the read character 1, but since there are a plurality of item names of “total sales” in the receipt, “print” is the print name on another unique receipt. The item of “Holding” is defined as a marker item. In addition to the reading position of the reading character 1 and the relative reading position 1 of the amount column corresponding to the item, information on the distance (including direction) from the marker item is defined. The distance information from the marker item indicates the upper limit value of the distance (x coordinate, y coordinate) from the character position of the marker item “loan amount” to the character position of the read character 1 “total sales”. As for the coordinates, when the read character 1 is present in the right direction, a positive value is assumed. The y-coordinate takes a positive value when the read character 1 exists in the upward direction, and takes a negative value when the read character 1 exists in the downward direction. In the example of FIG. 8A, this value is “(−50, +100)”, −50 (left direction) in the x coordinate from the character position of the marker item “loan amount”, and +100 in the y coordinate. This indicates that the read character 1 “total sales” to be collected exists within the range (upward).

  When the attribute value of an item attribute is 3, by defining multiple item names that are consecutively arranged in multiple lines as keywords and defining the multiple keywords to be unique in the receipt, the items with the same name One is specified as an actual reading item. In the example of FIG. 8B, “total sales” is the read character 1 necessary as a sales management item, but since there are a plurality of item names of “total sales” in the receipt, it is unique in the receipt. A series of items covering multiple lines, such as “total sales”, “net sales”, “cash amount”, and “loan amount”, are set as multiple keywords. The position of is specified. The reading position 1 of the reading character 1 is the upper left and lower right coordinates of the minimum rectangular area on which a plurality of keywords “total sales”, “net sales”, “cash amount”, and “loan amount” are printed. The relative reading position 1 in the money amount column is a coordinate defined with the upper left coordinate of the reading position 1 of the reading character 1 as the origin.

  Further, as the receipt definition data, the definition information of the arithmetic expression indicating the correspondence between the read item defined by the receipt definition data shown in FIGS. 7 and 8 and the sales management item in the basic table shown in FIG. 5 is set. Is done. FIG. 9 shows an example of receipt definition data that defines the arithmetic expression.

  As shown in FIG. 9, the definition information of the arithmetic expression has correspondence information between each sales management item and one or a plurality of read item identification codes in addition to the store code for identifying the store. When a plurality of reading items are associated with one sales management item, arithmetic expressions of four arithmetic operations for a plurality of reading item identification codes are used. In the example of FIG. 9, the read item identification code corresponding to the sales management item 1 “cash sales” is “A + B”. This is a value obtained by adding the numerical value printed in the amount column corresponding to the reading item with the reading item identification code = A and the numerical value printed in the amount column corresponding to the reading item with the reading item identification code = B, It shows that it is recorded as the amount of sales management item 1 “cash sales”. For the second sales management item 2 “paid sales”, the read item of the read item identification code “C” is used as the amount of “paid sales” as it is. Similarly for other sales management items, the correspondence information between each sales management item and the read item from the receipt is defined by the operation formula of the read item identification code (including the case of one-to-one correspondence).

  Next, an example of history data created by the history data creation unit 15 and stored in the history data storage unit 105 will be described with reference to FIG.

  The history data is collected so that the contents of the receipt definition data created by the definition data creation unit 14 can be used for creating receipt definition data at other stores in the same industry. As the industry information, the industry code, industry name, POS system information 1 to 3, payment receipt information 1 to 4 and the like are stored. In addition, as the item information, an identification code, an item attribute, a reading character, and the like of each reading item are stored. In addition, as the calculation information, an arithmetic expression using each sales management item and the corresponding read item identification code is stored. These specific contents are the same as the contents of the receipt definition data described with reference to FIGS.

  The history data creation unit 15 creates dictionary information as history data and stores it in the history data storage unit 105. FIG. 11 shows an example of the dictionary portion of the history data.

  In the history data dictionary section, as shown in FIG. 11, character string information (words, etc.) actually used for receipt definition data, such as industry code, POS system information, sales management items, read characters,... Is done. The character string information stored in the dictionary part is used to infer the reading items corresponding to the sales management items when the receipt definition data of a new store is created by using the created receipt definition data. For example, it can be used to extract a character string of a correct recognition result in the image data of the character recognition result described with reference to FIG. It can also be used to prevent erroneous recognition and erroneous input automatically in the actual sales management data collection operation.

  Next, the process executed by the receipt definition data creation device 1 will be described in more detail. 12 to 14 are flowcharts of the entire receipt definition data creation process according to the present embodiment.

  First, in step S201, an operator input from the input device 4 is waited. If the operator designates whether receipt definition data is newly created or created by referring to the created receipt definition data by using a menu or the like, the process proceeds to step S202.

  In step S202, it is determined whether the receipt definition data is newly created or reference created. If reference creation is made, the process proceeds to step 220 in FIG. 13, and if newly created, the process proceeds to step S203.

  In step S203, an initial screen of a definition input screen for creating receipt definition data is displayed on the display device 3.

  FIG. 15 shows a configuration example of the definition input screen. The definition input screen 30 includes a sales management item list display area 31, an OCR reading definition list display area 32, a receipt image display area 33, a marker below the display area of the facility for creating receipt definition data and tenant (store) information. A definition list display area 34 and a calculation formula input area 35 are provided.

  In the sales management item list display area 31, a sales management item list is displayed as shown in FIG. The sales management item list is calculated when an item name of the sales management item stored in the basic table described in FIG. 5 and a calculation formula (calculation formula) that associates the sales management item with the read item are determined. Has a field that displays an expression.

  In the OCR reading definition list display area 32, as shown in FIG. 16B, OCR reading items inputted by the operator's input operation and area information of the items in the receipt image are set. Information indicating whether or not (item area) and information (amount information) indicating whether or not the area information of the amount column corresponding to the item has been set are displayed.

  In the receipt image display area 33, an image (image data) of a receipt read by the reader 10 is displayed. In the display of this area, functions such as scrolling and enlargement / reduction are provided.

  The marker definition list display area 34 displays information for defining a unique marker item for specifying a reading item when there are a plurality of reading items with the same name in the receipt. In the calculation formula input area 35, a calculation formula for associating the input sales management item and the read item is displayed.

  In step S203, the initial screen of the definition input screen 30 as described above is displayed, and in step S204, an operator input is waited for. In step S205, when all the items have been input, the operator presses the “define definition” key. Therefore, it is determined whether or not the input has been made, and if the “define definition” instruction is input, step S208 is performed. Proceed to

  If there is no “define definition” instruction, the process advances to step S206 to input a reading item, select an item area, and select a money area. An example of this processing will be described with reference to FIGS.

  On the initial screen of the definition input screen 30, the OCR reading definition list display area 32 displays a reading item ID (for example, a) automatically given as shown in FIG. Area and amount area are displayed. Here, for example, when “net sales” is set as an input item by reading, “unset” indicating that the item area and the amount area in the receipt for the “net sales” item are not set. Are displayed in a conspicuous display color as shown in FIG. Therefore, the operator performs an item area setting operation and a monetary area setting operation.

  FIG. 17 is a diagram for explaining the setting of the item area. Assume that the display in the OCR reading definition list display area 32 is as shown in FIG. 17A, and the receipt image as shown in FIG. 17B is displayed in the receipt image display area 33. On the image in the receipt image display area 33, the operator points and drags or clicks the character string portion of “net sales” with the input device 4 such as a mouse. The coordinate acquisition unit 131 of the input data processing unit 13 detects this input, and displays the character string “pure sales” in the receipt image surrounded by a frame line. At this time, for example, as shown by the arrow in the left diagram of FIG. 17C, even if the character string portion of “net sales” is dragged greatly, the right side of FIG. A frame line is displayed with a minimum necessary size as shown by a dotted line frame in the figure. The upper left corner coordinates and lower right corner coordinates of the item area selected in this way are stored in the internal memory. In the OCR reading definition list, as shown in FIG. 17D, the item area column is rewritten from “not set” to “◯”, indicating that the item area selection processing has been completed. The automatic adjustment of the size of the area surrounded by the frame line can be performed by referring to the image data of the recognition result by the OCR described with reference to FIG.

  Similarly, the amount area selection process is performed by displaying a frame line by dragging or clicking the corresponding amount field in the receipt image with a mouse or the like, and taking in the coordinate information of the area. By setting the amount area, the amount area column in the OCR reading definition list is rewritten from “not set” to “◯”, and the definition for the reading item “net sales” is completed. The input field moves to the next line. If there is no entry field, a new entry field is automatically added. Instead of showing the area by displaying the frame line, the background or character display color may be changed to show the area.

  Subsequent to the reading item definition processing described above, in step S207, calculation definition processing is performed. The calculation definition process is a process for defining a calculation formula indicating the correspondence between the sales management item and one or more reading items defined in step S206. Details will be described later. Then, it returns to step S204 and repeats a process similarly.

  If there is an instruction for “definition of definition”, the process proceeds to step S208. In step S208, the reading item is rechecked. Here, character recognition is performed again for the item area of the read item. Alternatively, the recognition accuracy is determined based on the difference information for each recognized character of the read item in the recognized character data stored in the image data storage unit 101 described with reference to FIG. It is checked whether or not the recognition accuracy is worse than a predetermined threshold.

  If it is determined in step S209 that there is no recognition error, or if it is determined that the recognition accuracy is not bad, the process proceeds to step S230 in FIG. If not, the process proceeds to step S210 to prompt the operator to input a substitute item. Because the substitution item is difficult to recognize or has a high possibility of misrecognition of the original reading item, other receipt items are to be recognized as substitution items, and the original item is determined based on the relative position information from the substitution item. This is an item for the purpose of acquiring the amount of money for the read item. If there is an input operation of the substitute item from the operator, the substitute item definition process is performed in step S211. Thereafter, the process returns to step S204. Specific examples of alternative items will be described later with reference to FIG.

  When the receipt creation data reference creation is designated in step S202, the process proceeds to step S220, and an instruction is input to select the receipt definition data to be referred to manually or automatically. When selecting manually, it progresses to step S221. In step S221, information specifying a store code of a store for which receipt definition data has already been created is input, receipt definition data corresponding to the store code is acquired from the definition data storage unit 104, and the process proceeds to step S226.

  When the receipt definition data to be referred to is automatically selected, the process proceeds to step S222, and the history data stored in the history data storage unit 105 is referred to. Next, in step S223, the presence / absence of similar data is determined. The process for determining the presence or absence of similar data will be described later with reference to FIG.

  If it is determined in step S224 that there is no data similar to the receipt definition data of the store to be created in the history data, reference creation is not possible, so the process returns to step S203, and processing similar to that for new creation is performed. Execute.

  If it is determined that there is similar data in the history data, the process proceeds to step S225, and receipt definition data of the similar store is acquired.

  In step S226, the read item of the acquired store is inferred from the receipt definition data acquired in step S221 or step S225, and the definition input screen 30 is edited. That is, as an initial screen of the definition input screen 30, a screen with an empty OCR reading definition list is not displayed, but reading item data defined in the receipt definition data to be referred to and sales management in the sales management item list are displayed. Create and display a screen with the item formula embedded. Thereafter, the process proceeds to step S204. The processing after step S204 is the same as the processing described above. As a result, in the case of reference creation, the operator can easily create receipt definition data for a new store by simply modifying a portion different from the receipt definition data for the store to be referenced as necessary.

  If it is determined in step S209 described above that there is no reading item recognition error or the recognition accuracy is not bad, the process proceeds to step S230 in FIG. In step S230, the receipt item defined in step S206 is checked for an item of the same character string in the receipt. If it is determined in step 231 that there is an identical character string, the process proceeds to step S233. If it is determined that there is no identical character string, the process proceeds to step S232.

  In step S232, after the history data is created, the process ends. Details of the history data creation processing will be described later.

  If there is the same character string, in step S233, the same character string processing for specifying a necessary reading item is performed. Here, marker items and multiple keywords are set, which will be described in detail later. After the same character string processing, the process returns to step S204 and continues in the same manner.

  FIG. 18 is a flowchart showing details of the calculation definition process (step S207 in FIG. 12). The following processing is executed by the calculation definition unit 132 in the input data processing unit 13.

  In step S301, an input for the calculation definition is awaited. If there is an input, the process proceeds to step S302, and based on the input, a sales management item that defines the calculation and a reading item that is used for the calculation are selected. A reading item can be selected by specifying a reading item ID. One or a plurality of reading items may be selected.

  In step S303, an arithmetic operation operator is input and the operator is selected. Arithmetic symbols such as% and parenthesis symbols that specify the order of operations can also be used. The number of operators to enter depends on the number of selected reading items. In the case of one reading item, it is not necessary to input an operator.

  Until the selection of all necessary reading items and operators is completed by the determination process in step S304, the process returns to step S301 and the same process is repeated.

If the selection of the reading item and the operator is completed, the input operator is checked in step S305. This is the following check.
1) Is an undefined reading item ID used?
2) Is an operator that cannot be used specified?
3) Whether the result is within the allowable range when the amount is calculated using the set formula.

  Whether or not the result is within the allowable range is calculated based on the lower limit value of the corresponding sales management item stored in the basic table when it is calculated using the numerical value of the amount actually obtained from the receipt image data. Judgment is made based on whether the value is within the range.

  If an error is detected by the determination of the check result in step S306, the process returns to step S301 to reselect the reading item or re-enter the operator. If there is no error, the input calculation formula is displayed in the calculation formula column of the corresponding sales management item in the sales management item list, and the calculation definition for one sales management item is terminated. Calculation definition is basically performed for all sales management items, but may be undefined for sales management items for which no corresponding read item exists.

  FIG. 19 shows an example of calculation definition. As shown in FIG. 19A, in the OCR reading definition list display area 32, net sales (ID = a), consumption tax (ID = b), and cash voucher (ID = c) of reading items are defined. Suppose. Here, if the sales management items “total sales” and “gift certificate” have a corresponding relationship with the read items as shown in FIG. 19B, as shown in FIG. 19C, Define a calculation formula of “a + b” for “total sales” and a calculation formula of “c” for “gift certificate”. By setting this calculation formula as the operation definition in the receipt definition data, the amount of the sales management item can be calculated from the actual receipt issued by the store.

  FIG. 20 shows an example in which the correspondence between the receipt of a certain store and the sales management item is defined by a calculation formula. Receipt reading items generally differ from store to store, so the correspondence between sales management items required by the tenant management department and receipt reading items at each store differs from store to store. However, as shown in FIG. 20, since a calculation formula can be defined for each store, it is possible to flexibly associate sales management items with receipt items.

  FIG. 21 is a flowchart showing details of the same character string processing (step S233 in FIG. 14). The following processing is executed by the multiple keyword setting unit 133 and the marker item setting unit 134 in the input data processing unit 13.

  In step S401, an alarm indicating that there are a plurality of reading items defined in the OCR reading definition list display area 32 having the same name is displayed, and an input from the operator is waited.

  In step S <b> 402, it is determined whether a reading item in the same name is specified by a marker item or a plurality of keywords in response to an input from the operator. If a marker item is selected, the process proceeds to step S403, and if a plurality of keywords are selected, the process proceeds to step S406.

  In step S403, input of marker items is waited. The marker item input method is the same as the input method in the item area setting described with reference to FIG. In step S404, the coordinates of the character item of the designated marker item are acquired. In step S405, the direction indicating whether the reading item actually used in the definition is in the upward direction or the downward direction and the distance from the marker item are calculated. If the reading item is in the upward direction of the marker item, the distance is defined as a positive value, and if it is in the downward direction, the distance is defined as a negative value. A distance corresponding to a predetermined number of lines may be added to the distance value as a margin in consideration of fluctuations in the line position of the reading item in a receipt that is actually issued every day.

  FIG. 22 shows a definition example of marker items. In the receipt image displayed in the receipt image display area 33 shown in FIG. 22A, it is assumed that the reading item actually required as a sales management item is “consumption tax”. Here, there are a plurality of items with the same name “consumption tax”, and it is assumed that “consumption tax” above is an item to be defined as a read item. Therefore, another item unique in the receipt (in this example, “return item”) is defined as a marker item.

  That is, as shown in FIG. 22B, it is assumed that the marker item is “returned goods details” and the distance to “consumption tax” is “110” in the right direction and “100” in the upward direction. At this time, (110, 100) is defined as the distance from the marker item “details of return” to the read item “consumption tax”.

  The number of marker items is not limited to one, and a plurality of marker items may be defined. In the example of FIG. 22C, in addition to defining “returned goods details” as a marker item, a marker item is also defined for “sales details”. In this case, only the read items that satisfy the conditions defined by the definition of all marker items are extracted as the corresponding read items. If the read item does not satisfy any of the marker item definition conditions, Will be certified.

  If it is determined in step S402 in FIG. 21 that the reading item is specified by a plurality of keywords, the process proceeds to step S406, and the input of the plurality of keywords is awaited. If there is an input of a plurality of keywords, in step S407, the character items of the plurality of keywords and the coordinates of the amount area are acquired, and the plurality of keywords are defined.

  FIG. 23 shows an example of setting a plurality of keywords. In the example of FIG. 23, there are three character items having the same name as the read item “total sales”, Str # 12, Str # 22, and Str # 32. In addition, there are three character strings corresponding to each of Dat # 12 “¥ 168,735”, Dat # 22 “¥ 48,195”, and Dat # 32 “¥ 32,025”.

  If the read item required here is “total sales” of Str # 12, the read item of Str # 12 cannot be specified only by the character string of “total sales”. Therefore, a plurality of character items including Str # 12 are included. Is defined as a plurality of keywords Key # 1. In this example, “total sales”, “net sales”, “cash balance”, and “lending balance” are defined as a plurality of keywords Key # 1. In this receipt definition data, “3” indicating a plurality of keywords is defined as item attribute # 1, and “total sales”, “net sales”, “cash balance”, and “loan amount” are defined as read character # 1. To do. Further, the relative reading position # 1 of the amount column of the amount character string Dat # 12 necessary for collecting the sales management items is also defined in the receipt definition data. As a result, even if there are a plurality of character strings of “total sales” in the receipt, if multiple keywords are unique, the reading item of “total sales” included in the character string matching the plurality of keywords is specified. It will be.

  FIG. 24 is a diagram illustrating an example of setting alternative items. Processing performed by the alternative item processing unit 135 in steps S210 and S211 of FIG. 12 described above will be described.

  Now, as shown in FIG. 24A, it is assumed that the consumption tax is defined in the OCR reading definition list display area 32, and the coordinate information is also acquired for the item area. Here, with respect to the original image of the receipt that is the display source of the receipt image display area 33 shown in FIG. If it is actually recognized as “consumption tax” entered by the operator, the substitute item is not processed because it is correct. If there is a recognition error due to recognition of a different character, as shown in FIG. 24 (B), a warning prompting the user to enter an alternative item “This character string is difficult to read. Please specify an alternative item.” Output a message. Instead of actually performing the OCR process, the recognition accuracy may be estimated from the recognized character data shown in FIG.

  When the warning message as shown in FIG. 24B is output, the operator designates an easy-to-read receipt item such as “subtotal” in the receipt image display area 33 of FIG. 24C as an alternative item. To do. The substitute item may be either above or below the original reading item (consumption tax), but it is desirable that the line is close. As in this example, when “subtotal” is specified as an alternative item, the information on the relative reading position of the amount “¥ 7,234” corresponding to the consumption tax is included in the receipt definition data from “consumption tax”. Relative position from “subtotal” that is easy to read is defined, not relative position.

  In addition, in order to show that the item is defined by the substitute item, the substitute item “subtotal” and the original read item “consumption tax” are displayed in the OCR reading definition list display area 32 as shown in FIG. They are displayed concatenated with a predetermined separator “!”. Also in the receipt definition data, as shown in FIG. 7B, the read character is defined as “subtotal! Consumption tax”, indicating that it is defined by an alternative item.

  FIG. 25 is a flowchart showing details of the process for determining the presence or absence of similar data (step S223 in FIG. 13).

  When creating receipt definition data for a new store, whether or not there is similar data in order to automatically extract similar receipt definition data from history data when referring to already created receipt definition data Judging. First, in step S501, the store master 103 is referred to. In step S502, the history data stored in the history data storage unit 105 is referred to.

  As a result of referring to steps S501 and S502, the business type code of the new store that newly creates receipt definition data is the same as the business type code in the history data, and the POS system information in the new store and the POS system information in the history data Are determined in steps S503 and S504. As a result of the determination, if both are equal, the process proceeds to step S506. If neither is equal, the process proceeds to step S505, and the determination result is “no similarity”.

  On the other hand, in step S506, it is determined that “similarity exists”, and in step S507, history data (dictionary part) is referred to. In step S508, the reading item corresponding to the sales management item is inferred from the result of referring to the history data (dictionary part).

  FIG. 26 is a flowchart showing details of the history data creation process (step S232 in FIG. 14).

  In step S601, the store master 103 is referenced from the store code of the store for which the receipt definition data has been newly created. In step S602, the corresponding industry code, POS system information, and payment receipt information are acquired from the store master 103. In step S603, item information and calculation information are acquired from the created receipt definition data. In step S604, history data and a history data dictionary as shown in FIGS. 10 and 11 are created and stored in the history data storage unit 105.

  The processing for creating the receipt definition data described above can be realized by a computer and a software program, and the program can be recorded on a computer-readable recording medium or provided through a network.
