Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a functional block diagram of the information processing apparatus.
The information processing apparatus 10 includes a barcode detection unit 11, a storage unit 12, and an image processing unit 13.

The barcode detection unit 11 detects a two-dimensional barcode from a captured image of the three-dimensional object 30 captured by an imaging device 20 such as a CCD (Charge Coupled Device) camera.
The three-dimensional object 30 includes, for example, a doll 30a and a pedestal 30b as shown in the figure. In this example, the two-dimensional barcode 30c is arranged on each surface except the upper surface of the pedestal 30b. The two-dimensional barcode 30c includes identification information unique to the three-dimensional object 30 (hereinafter referred to as unique information) and identification information for identifying a position or direction on the three-dimensional object 30 on which the two-dimensional barcode 30c is arranged (hereinafter, referred to as unique information). (Referred to as position / direction information). For example, the position / direction information is coded in each of the two-dimensional barcodes 30c arranged at the positions corresponding to the front surface, right side surface, left side surface, back surface, and bottom surface of the doll 30a.

  For example, in a two-dimensional barcode 30c having 24 bits, 3 bits are assigned to direction indications (front, right side, left side, back side, bottom side if necessary), the front side is “white and white”, and the right side is “white black and white” The left side can be expressed as “monochrome white”, the back side as “black and white black”, and the bottom side as “black white”. The other bits are used to express unique information unique to the three-dimensional object 30, and the same unique information is coded for each direction to express that the same product has different directions. In addition, the barcode administrator can freely set the group and category.

The storage unit 12 stores a spatial positional relationship between the two-dimensional barcode and the three-dimensional object 30.
FIG. 2 is a diagram illustrating a spatial positional relationship between a two-dimensional barcode and a three-dimensional object.
As shown in this figure, XYZ coordinates are set with the lower left corner of the logo portion 30d of the two-dimensional barcode 30c arranged on the front side of the three-dimensional object 30 as the origin, and the spatial position of the three-dimensional object 30 is set. Express. For example, the coordinates of the right hand tip, left hand tip, right foot tip, and left foot tip of the doll 30a are stored in the storage unit 12 in advance as the positional relationship table 12a. Note that not all coordinates of the three-dimensional object 30 are recorded due to problems with the capacity of the storage unit 12 and processing capability, but several feature points of the three-dimensional object 30 and coordinates of a standing plane are recorded in advance. Just keep it.

The image processing unit 13 refers to the positional relationship between the detected two-dimensional barcode 30c and the three-dimensional object 30, and generates and outputs a CG image that matches the spatial position of the three-dimensional object 30.
Hereinafter, the operation of the information processing apparatus 10 will be described.

  When the three-dimensional object 30 is placed at a predetermined position with respect to the imaging device 20 and imaging is started, the information processing device 10 captures the captured image, and the barcode detection unit 11 detects the two-dimensional barcode 30c from the captured image. . The recognition of the two-dimensional barcode itself is disclosed in, for example, Japanese Patent Laid-Open No. 2000-82108 (paragraph numbers [0055] to [0112]), and the two-dimensional barcode is inclined with respect to the imaging system. Even in such a state, it can be recognized.

  The image processing unit 13 refers to the positional relationship between the detected two-dimensional barcode 30c and the three-dimensional object 30 from the storage unit 12, and generates a CG image that matches the spatial position of the three-dimensional object 30, for example, As shown in FIG. 1, it is output and displayed on a display unit 40 such as a display. At this time, the image processing unit 13 refers to the unique information of the detected two-dimensional barcode 30c and performs pre-registered image processing on the three-dimensional object 30 corresponding to the unique information. Since the positional relationship between the two-dimensional barcode 30c and the three-dimensional object 30 is known from the positional relationship table 12a shown in FIG. 2, for example, as shown in the figure, the CG image 41 appears from the position of the hand of the doll in the captured image. By combining them as described above, an expression as if the three-dimensional object 30 of the captured image is moving is also possible. That is, an image combined with the three-dimensional object 30 can be expressed.

  Although the case where the two-dimensional barcode 30c on the front of the doll 30a is detected is shown here, for example, even when the side surface, the back surface, or the bottom surface is directed toward the imaging device 20, the surface of the doll 30a A CG image corresponding to the position or direction can be generated by detecting the correspondingly arranged two-dimensional barcode 30c and referring to position / direction information for identifying the position or direction. By providing the two-dimensional barcode 30c with position / direction information, the information processing apparatus 10 can easily recognize at which position the three-dimensional object 30 is located and in which direction it is facing.

  As described above, according to the information processing apparatus 10 of the present embodiment, since a three-dimensional object can be recognized using the two-dimensional barcode 30c, a new video expression using the captured three-dimensional object becomes possible. .

For example, on the basis of the stored positional relationship, it is possible to easily express a three-dimensional object from a captured image or display a CG image instead of the erased three-dimensional object.
FIG. 3 shows an example in which the captured three-dimensional object is deleted and replaced with a CG image.

  The three-dimensional doll 30a actually captured in this way is displayed on the screen by another character 41a as a CG. When the user changes the orientation of the doll 30a with respect to the imaging device 20, the detected two-dimensional barcode is changed accordingly, and the position / direction information of the two-dimensional barcode is recognized. Video expression that changes the direction of 41a is also possible.

  As examples of CG and images to be displayed, a three-dimensional object itself is displayed as a CG image on the screen of the display unit 40 such as a display to express an interactive game or the like. In addition, a live-action image of an object different from the object may be presented.

Next, a specific hardware configuration example of the information processing apparatus 10 according to the present embodiment will be described.
FIG. 4 is a hardware configuration example of the information processing apparatus.
The information processing apparatus 10 is, for example, a PC (Personal Computer), a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an HDD (Hard Disk Drive) 104, a graphic processing unit. 105, an input I / F (Interface) 106, a communication I / F 107, and the like, which are connected to each other via a bus 108.

  Here, the CPU 101 controls each unit according to programs stored in the ROM 102 and the HDD 104 and various data. Then, processing for recognizing a two-dimensional barcode is performed.

The ROM 102 stores basic programs and data executed by the CPU 101.
The RAM 103 stores programs being executed by the CPU 101 and data being calculated.

  The HDD 104 stores various data such as an OS (Operating System) executed by the CPU 101, various application programs, and the positional relationship table 12a indicating the positional relationship between the three-dimensional object and the two-dimensional barcode described above. The positional relationship table 12a may be recorded on a recording medium (not shown) such as a DVD (Digital Versatile Disc) or a CD-ROM, and these various data are partially expanded in the RAM 103, for example, the CPU 101. Used by.

  For example, a display 105 a is connected to the graphic processing unit 105 as a display device, and the function of the image processing unit 13 in FIG. 1 is realized in cooperation with the CPU 101. For example, in accordance with a drawing command from the CPU 101, a captured image, a CG image, or the like is displayed on the display 105a.

  The input I / F 106 is connected to an input device such as a mouse 106a, a keyboard 106b, and the camera 106c that is the imaging device 20 shown in FIG. The data is transmitted to the RAM 103 or the like and made usable by the CPU 101.

The communication I / F 107 is connected to the network 107a, for example, and communicates with a server or a terminal on the network 107a.
Hereinafter, the details of the processing of the information processing apparatus 10 having the hardware configuration as shown in FIG. 4 will be described using a flowchart.

  For example, when a user places a three-dimensional object within the imaging range of the camera 106c and, for example, a program for performing a two-dimensional barcode recognition process stored in the HDD 104 is extracted and executed, the CPU 101 performs the following depending on the program: The process shown in is performed.

FIG. 5 is a flowchart for explaining the flow of recognition processing of a two-dimensional barcode.
The information processing apparatus 10 captures an image captured by the camera 106c via the input I / F 106 (step S1). The captured image is temporarily stored in the RAM 103, and the CPU 101 detects a two-dimensional barcode from the captured image (step S2). The CPU 101 determines whether or not a two-dimensional barcode is detected by detecting the process in step S2 (step S3). If the two-dimensional barcode is not detected, for example, this is displayed and the user is prompted to adjust the distance and angle of the three-dimensional object on which the two-dimensional barcode is arranged with respect to the camera 106c. Then, the process returns to step S1. On the other hand, when a two-dimensional barcode is detected, various identification information such as unique information, position / direction information regarding the position or direction, and the positions of the four vertices of the two-dimensional barcode are detected from the two-dimensional barcode. The two-dimensional coordinates shown are acquired and stored in, for example, the RAM 103 (step S4). The CPU 101 determines whether the acquired various types of identification information have already been stored in the HDD 104 or the like and has been registered (step S5). If the information has been registered, the graphic processing unit 105 is controlled under the control of the CPU 101. Performs a registered three-dimensional image display process (step S6). If not registered, various types of identification information are registered in the HDD 104, for example, and processing to be performed when the identification information is detected is also registered (step S7).

  The processes up to step S7 described above are substantially the same as the two-dimensional barcode recognition process disclosed in Patent Document 1, for example. In the information processing apparatus 10 according to the present embodiment, the CPU 101 further determines whether or not a plurality of unique information has been acquired from the detected two-dimensional barcode (step S8). If a plurality of unique information is not acquired, the processing from step S1 is repeated. When a plurality of pieces of unique information are acquired, the CPU 101 determines whether or not the pieces of unique information are unique information of the same product, that is, the same three-dimensional object (step S9).

FIG. 6 is a diagram illustrating a case where a plurality of three-dimensional objects are captured.
When the two three-dimensional objects 30 and 31 are imaged in the arrangement as shown in FIG. 6, four two-dimensional barcodes 30c-1, 30c-2, 31c-1, and 31c-2 are detected, and accordingly Four pieces of unique information are acquired. Here, since the two-dimensional barcodes 30c-1 and 30c-2 are arranged on the same three-dimensional object 30, the unique information is the same. Since the two-dimensional barcodes 31c-1 and 31c-2 are also arranged on the same three-dimensional object 31, the unique information is the same.

  If there is no unique information of the same three-dimensional object in the process of step S9, the process from step S1 is repeated. As shown in FIG. 6, when there is unique information of the same three-dimensional object, various kinds of identification information registered with a two-dimensional barcode having a large projected area are set with priority, and a two-dimensional bar having a small projected area is set. The code is ignored (step S10). Then, the processing from step S1 is repeated. In the case of FIG. 6, among the two-dimensional barcodes 30c-1 and 30c-2 having the same unique information, various identification information of the two-dimensional barcode 30c-1 having a large projected area is preferentially set. Similarly, in the two-dimensional barcodes 31c-1 and 31c-2 having the same unique information, the two-dimensional barcode 31c-1 having a large projected area is preferentially set.

Next, the 3D image display process using the 2D barcode performed in the process of step S6 will be described.
FIG. 7 is a flowchart for explaining the flow of the three-dimensional image display process.

  The CPU 101 acquires various identification information of the two-dimensional barcode detected by the two-dimensional barcode recognition processing shown in FIG. At this time, if there is specific information that is preferentially set, it is given priority (step S20). Thereafter, under the control of the CPU 101, the graphic processing unit 105 generates a three-dimensional image display window on the display 105a (step S21). The CPU 101 reads out data registered in association with the three-dimensional object from the HDD 104, for example, in accordance with the acquired unique information and position / direction information (step S22). The data associated with the three-dimensional object is, for example, data for displaying a three-dimensional image corresponding to the three-dimensional object (such as data described as an X file that is a standard file format used in Microsoft Direct 3D). And the sound to be reproduced, the information on the animation, and the positional relationship table 12a between the two-dimensional barcode and the three-dimensional object as shown in FIG.

  Thereafter, the two-dimensional coordinates of the two-dimensional barcode acquired in step S4 in FIG. 5, the focal length of the camera 106c, and the like are read from, for example, the RAM 103 (step S23). The CPU 101 calculates the three-dimensional coordinates for indicating the position where the three-dimensional image is displayed with reference to the acquired two-dimensional coordinates, the focal length, and the read positional relationship table 12a (step S24). Then, under the control of the CPU 101, the graphic processing unit 105 displays a three-dimensional image corresponding to the three-dimensional coordinates calculated in step S24 (step S25), and from the three-dimensional image display process to step S8 in FIG. Return to processing (return).

  As described above, by referring to the positional relationship table 12a indicating the positional relationship between the two-dimensional barcode and the three-dimensional object, a CG image corresponding to the spatial position with the three-dimensional object can be displayed.

  In the above description, the case where the two-dimensional barcode 30c is installed on the pedestal 30b of the three-dimensional object 30 as shown in FIG. 1 has been described. For example, when the doll 30a is sufficiently large, the doll 30a is placed at a predetermined position. Even if a two-dimensional barcode is installed, the same processing as described above is performed.

FIG. 8 is a diagram showing a state in which a two-dimensional barcode is installed on a certain doll.
A two-dimensional barcode 32c is arranged on a doll 32 which is a three-dimensional object. However, in such a case, depending on the shape of the three-dimensional object, the two-dimensional barcode may enter the blind spot, and it is necessary to devise the arrangement so that at least one two-dimensional barcode is always visible. Since it cannot be recognized that the entire two-dimensional barcode is not visible to the imaging system, for example, it cannot be naturally placed behind a recessed place or a projection. Depending on the shape of the three-dimensional object, there are some that can be turned over or lying down. Therefore, for such a thing, it is necessary to install a two-dimensional barcode in each direction. In the case where there is a movable part, the two-dimensional barcode is hidden depending on the posture of the movable part. For this reason, for example, it is necessary to arrange the two-dimensional barcode on the hand. In addition, for example, in the case of a large one, the position information may be further expressed such as on the front side or below the front side.

  In the above description, the PC as shown in FIG. 4 has been described as an example of the information processing apparatus 10. However, the present invention is not limited to this, and a game machine, a mobile phone, a PDA (Personal Digital Assistant), A television having a CG generation processing capability may be used.

  In addition, the three-dimensional object can be realized by any three-dimensional object including a figure, a game piece, and a toy. It is conceivable that data for processing is also supplied through any medium (disk media, memory, network distribution, data broadcasting, etc.).

  Thus, for example, when a can or bottle such as a soft drink with a two-dimensional barcode placed thereon is imaged, a program associated with the unique information of the two-dimensional barcode (a program distributed through a network may be used). ), It is also possible to cause a special effect video having an advertising effect to appear on the screen at a predetermined position.

  As described above, any three-dimensional object can be recognized and combined with CG or an image. As a result, since a three-dimensional object can be taken into the display screen and interactively processed, an application such as a game using a three-dimensional object or reproduction of a special effect can be realized. In addition, an advertising effect can be obtained by combining with a character product.

  The above processing contents can be realized by a computer. In that case, a program describing the processing contents of the functions that the information processing apparatus 10 should have is provided. By executing the program on a computer, the above processing functions are realized on the computer. The program describing the processing contents can be recorded on a computer-readable recording medium. Examples of the computer-readable recording medium include a magnetic recording device, an optical disk, a magneto-optical recording medium, and a semiconductor memory. Examples of the magnetic recording device include a hard disk device (HDD), a flexible disk (FD), and a magnetic tape. Optical disks include DVD, DVD-RAM, CD-ROM, CD-R (Recordable) / RW (ReWritable), and the like. Magneto-optical recording media include MO (Magneto-Optical disk).

  When distributing the program, for example, a portable recording medium such as a DVD or a CD-ROM in which the program is recorded is sold. It is also possible to store the program in a storage device of a server computer and transfer the program from the server computer to another computer via a network.

  The computer that executes the program stores, for example, the program recorded on the portable recording medium or the program transferred from the server computer in its own storage device. Then, the computer reads the program from its own storage device and executes processing according to the program. The computer can also read the program directly from the portable recording medium and execute processing according to the program. In addition, each time the program is transferred from the server computer, the computer can sequentially execute processing according to the received program.
