Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for automatically creating a construction area control chart and an apparatus therefor, and in particular, construction area polygons of various facilities such as gas pipes, water pipes, communication lines, and power cables installed on roads, and construction target facilities. The present invention relates to a computer mapping system for automatically creating a construction area control chart in which explanatory information and leader lines thereof are written. This construction area management chart is a small scale drawing (1/2500, 1/5000, 1/8000, etc.), and is used in road adjustment meetings. In the following explanation, “explanation information etc.” is used as a term indicating both the explanation information of the construction target facility and the corresponding leader line as necessary.
[0002]
In general, when constructing various road-related facilities, each public business entity individually enters the construction area and explanation information into a common road drawing (such as a road ledger map) and displays them together. However, it is not uncommon for many of the leaders and explanation information to be concentrated in the same construction area on the drawing due to overlapping construction areas of each public corporation.
[0003]
For this reason, it is desirable to make the explanation information easy to see by avoiding at least duplication and complication of explanation information as much as possible by widening the display area of the leader line and explanation information. It is a response to a serious request.
[0004]
The construction area control chart generally does not include facility lines indicating the specific installation status of various facilities such as gas pipes, water pipes, communication lines, and power cables. If you want to grasp it, you will need to refer to the facility control chart separately.
[0005]

[0010]
When the leaders obtained by the above processing procedure and the explanation information written there overlap or are complicated, the processing conditions are changed, for example, the previously used polygon region outside the road is excluded from the selection target, or the intermediate point B The setting process is repeated after changing the intervals between .about.B ″.
[0011]
The value of the predetermined length L in step (3) ′ is the maximum value of the length of each explanation information guide line (BC), (B′−C ′), (B ″ −C ″). It is set in advance so that “L ≧ k ′” with respect to k ′.
[0012]
Further, the interval between the intermediate points B to B ″ in step (4) ′ is arbitrary. For example, even division, non-uniform division taking into account the difference in the number of character stages described in the explanation information guide section of each leader line, etc. Is used.

[0021]
[Problems to be solved by the invention]
As described above, in the conventional setting method of the leader line (explanation information guide line) and the explanation information display area in the large scale drawing such as the private property ledger, the target range is surrounded by the road line indicating the road boundary or the side groove. Only the polygonal area outside the road.
[0022]
For this reason, when the total number of explanation information guide lines to be shown in the same polygonal area outside the road and the total number of explanation information stages are numerous, there is a problem that the explanations of the explanation information and the like are duplicated or complicated. It was.
[0023]
Therefore, in the present invention, the setting range of the explanation information and the like is the entire outside portion of the construction area polygon, and at least the overlap of the explanation information display area is avoided, and further, the intersection of the auxiliary line portion of the leader line is reduced. Therefore, the purpose is to make the explanation information and the like written on the construction area control chart easier to see and to enhance the convenience.
[0024]
[Means for Solving the Problems]
FIG. 1 is a basic configuration diagram of the present invention.
In the figure,
Reference numeral 11 denotes a construction area management chart creation target area, for example, divided into a plurality of meshes.
Reference numeral 12 denotes a polygon composing line indicating a construction area. For example, an overlap flag “1” is set for each mesh passing through this line, and an internal flag “2” is set for each mesh therein.
Reference numeral 13 denotes an explanation information guide line. For example, a leader line flag “3” is set on each mesh corresponding thereto.
Reference numeral 14 denotes a display area for explanation information. For example, a leader line flag “3” is set on each mesh corresponding thereto.
It is an input means and inputs data such as construction area and leader line.
Reference numeral 15 denotes an auxiliary line, which connects the starting point of the leader line (point A: see FIG. 10) and an arbitrary part of the explanation information guide line.
Reference numeral 16 denotes construction area setting means, which sets a polygon constituting line 12 indicating a construction area based on an instruction from the operator.
Reference numeral 17 denotes a leader line setting means, which extracts the entire outer portion of the polygon constituting line 12 based on the output data of the construction area setting means 16 and the operator instruction data, for example, an overlap flag “1” and Extract the mesh part where the internal flag “2” is not set, and set the explanation information guide line 13 and the explanation information display area 14 in the extraction area so that they do not overlap with those of other leader lines. A leader line flag “3” is set, and an auxiliary line corresponding to the display area is set.
[0025]
The operator's instructions for the construction area are
・ Each feature point of polygon composition line
・ Each feature point of the reference line for automatic polygon creation
Any one of them.
[0026]
  In the latter case, the construction area setting means 16 uses, for example, the polygon creation method proposed by the present applicant (JP 9-185700 AAfter the construction area polygon around the reference line is created, the leader line setting means 17 executes the above-described processing for this polygon constituent line.
[0027]
The operator's instructions on the leader line are
-Start point A, intermediate point B, end point C, number of description information steps, size of character (explanation information)
The start point A, the length of the explanation information guide line 13, the number of explanation information steps, the size of characters (explanation information), etc. Of these data, for those using a preset reference value, a new instruction can be omitted.
[0028]
Regarding the intermediate point and the end point in the former instruction data, the distance between the two points, that is, the length of the explanation information guide line 13 is significant as in the latter instruction data. The size in the longitudinal direction of the display area 14 for the description information is determined based on the length of the description information guide line 13, and the size in the direction orthogonal thereto is determined based on the number of description information steps and the size of the characters (explanation information).
[0029]
It should be noted that it is optional whether to divide the construction area control chart creation target area 11 into a plurality of meshes and use the various flags, and if the technique is not adopted, explanation of the instructed length The information guide line 13 and the display area 14 for explanation information corresponding to this overlap with the other leader lines in the area identified as the outer part of the construction area polygon based on each formula showing the polygon composition line 12. It will be set in a way that does not.
[0030]
In the following description, for convenience of explanation, it is assumed that the construction area management chart creation target area 11 is divided into a plurality of meshes and the above-described overlap flag, internal flag, and leader line flag are used for the predetermined part.
[0031]
The outline of the processing procedure of the leader line setting means 17 is as follows.
(1) An overlap flag “1” is set on each mesh through which the polygon constituting line 12 passes.
{Circle around (2)} For the polygons in the same construction area, the internal flag “2” is set on each mesh sandwiched between the meshes with the overlap flag “1”.
(3) The mesh area corresponding to the explanation information guide line 13 and the explanation information display area 14 is set to a range where the overlap flag “1” or the internal flag “2” is not raised, and is drawn to each mesh in this setting range. Set the line flag “3”.
(4) An auxiliary line 15 connecting the explanation information guide line 13 and the start point of the leader line is set.
[0032]
When setting the mesh area in step (3), the mesh having the leader line flag “3” is excluded from the setting target, so that the mesh area corresponding to the explanation information guide line 13 and the explanation information display area 14 Duplication can be avoided.
[0033]
In the mesh area setting process, the length data of the explanation information guide line 13 and the explanation information stage number data described above are used, and the respective reference values are used unless otherwise specified.
[0034]
Here, the explanation information guide line 13 may be set at the boundary line between the meshes. In this case, the mesh necessary for setting the explanation information guide line itself is, for example, the boundary line as the lower side. The mesh also serves as a display area 14 for explanation information.
[0035]
Also, by setting each of the explanation information guide lines 13 in the same direction, for example, in the X-axis direction of the drawing, it is possible to make the explanation information on the construction area control chart easier to see.
[0036]
In addition, when the auxiliary lines 15 that have been set once intersect, the auxiliary lines are replaced with each other, that is, by replacing the starting point that is the counterpart of the explanation information guide line 13, the display of the entire leader line can be simplified. it can.
[0037]
Whether or not to display the explanation information guide line 13 on the construction area control chart is arbitrary, and further, the length data of the explanation information guide line 13 is the data about the explanation information display area 14. It may be recognized that the explanation information guide line is equivalent to a line indicating the longitudinal direction (for example, the bottom side) of the display area, and the leader line in this case is grasped only by the auxiliary line 15. .
[0038]

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS.
In the following explanation, it is assumed that the same hardware as in FIG. 9 is used, and road line records and construction area polygon records necessary for creating the construction area control chart are already stored in the external storage device 33. In addition, for convenience of explanation, it is assumed that there is a leader line composed of an auxiliary line and an explanation information guide line.
[0041]
2 and 3 are explanatory diagrams showing a flag setting process procedure for each mesh in a construction area management chart creation target area, and the contents thereof are as follows.
(1) Define the following variables and go to the next step.
・ Two-dimensional array (for example, size of 500 x 350) corresponding to all meshes in the construction area control chart creation area
-Flag F (p, q, r, s) indicating the inclusion relation of each mesh (ie each two-dimensional array) with the construction area polygon
・ N indicating the record number of the construction area polygon record
J indicating the number of the line element specified in the coordinate data section 44 (see FIG. 10) of the construction area polygon record
(2) Clear the flag of each mesh to F (0,0,0,0) and go to the next step.
(3) Set the variables n and j as follows and proceed to the next step.
・ "1 → n"
・ "1 → j"
(4) The construction area polygon record of record number n is taken out from the external storage device 33 and the process proceeds to the next step.
(5) Calculate an expression indicating the j-th line element of this construction area polygon record, and proceed to the next step. Note that the j-th line element is (X in the coordinate data section 44 of the construction area polygon record._j, Y_j) And (X_k, Y_k), A line segment connecting the feature points, that is, a line element of a polygon constituent line, and k = j + 1.
(6) By using this calculation formula, a mesh on the j-th line element is extracted, and the process proceeds to the next step.
(7) Whether the j-th line element is facing upward, ie “Y_j<Y_kThe process proceeds to the next step if “YES”, and proceeds to step (9) if “NO”.
(8) Set q and r in the flag element of the extracted mesh to “1”, and proceed to step (10).
(9) Set p and r in the flag element of the extracted mesh to “1”, and proceed to the next step.
[0042]
The flag elements p, q, r, and s are
・ "1" in p means that the line element is downward or parallel to the x-axis at the corresponding mesh.
・ "1" in q indicates that the line element is upward in the corresponding mesh
・ "1" in r means that the corresponding mesh is inside the construction area polygon, and "0" is outside.
-“1” of s indicates that the corresponding mesh is selected as a mesh region in step (25) described later.
Respectively. In addition, the inside of a construction area polygon means that the mesh on the line element of the said polygon is included.
[0043]
That is, the flag F of each mesh on the line element is as shown in FIG.
・ F (0,1,1,0) for meshes that only support upward line elements
・ F (1,0,1,0) for meshes that only support downward line elements
・ F (1,1,1,0) for meshes corresponding to upward and downward line elements
It becomes.
[0044]
(10) It is determined whether or not the processing has been completed for all the line elements of the construction area polygon record. If “YES”, the process proceeds to step (12), and if “NO”, the process proceeds to the next step.
(11) Return to step (5) as “j + 1 → j”.
(12) It is determined whether or not the processing has been completed for all construction area polygon records in the creation target area. If “YES”, the process proceeds to step (14), and if “NO”, the process proceeds to the next step.
(13) As “n + 1 → n”, return to step (4).
(14) Extract all the upward meshes with the flag of F (0,1,1,0), that is, meshes through which only the upward line elements pass, and proceed to the next step.
(15) The flag element q of the mesh next to the right is sequentially checked from each of the upward meshes, and a downward mesh in which the flag element is set to “1”, that is, a mesh corresponding to at least the downward line element is encountered. An inner flag of F (0,0,1,0) is set to each mesh until.
[0045]
FIG. 4 is an explanatory diagram showing the flag setting status for each mesh in the creation target area of the construction area control chart, and the flag setting process in FIGS.
・ As described above, F (0,1,1,0), F (1,0,1, F) are applied to the mesh areas 18-1 to 18-3 through which the polygon composition line 12 'indicating the construction area passes. 0) or F (1,1,1,0) overlap flag
・ Inside mesh area 19 of polygon composition line 12 ', F (0,0,1,0) inner flag is
-The outer flag of F (0,0,0,0) is set in the outer mesh area 20 of this polygon constituting line 12 '.
Each is set.
[0046]
The mesh area 18-1 is an upward mesh, the mesh area 18-2 is a downward mesh, the mesh area 18-3 is an upward / downward mesh, and when the polygon constituent line 12 'passes through the boundary between meshes, All meshes in contact are defined as mesh regions 18-1 to 18-3.
[0047]
Here, the construction area polygon record indicating the polygon composition line (G-HI-J-K-L-M-N-G) shown in the figure is in the coordinate data section 44 (see FIG. 10). , The coordinate data of each feature point from point E to point M is held in order from the point E in the clockwise direction.
[0048]
When the upward mesh with the flag F (0,1,1,0) is set as a reference in step (14) or (15), the flag element p of the right adjacent mesh is used instead of the left adjacent one. The reason for sequentially checking is to keep this clockwise direction.
[0049]
The processing content of step (14) and (15) is whether the feature points of the polygon constituent lines in the construction area polygon record are held clockwise or counterclockwise, and as the reference mesh in that step It depends on whether you use an upward mesh or a downward mesh.
[0050]
That is,
・ When the setting order of each feature point is clockwise and the downward mesh is used as a reference, the flag elements q of the meshes to the left of the reference mesh are sequentially checked.
When the setting order of each feature point is counterclockwise and the upward mesh is used as a reference, the flag element p of the mesh next to the reference mesh is sequentially checked.
When the setting order of each feature point is counterclockwise and the downward mesh is used as a reference, the flag element q of the mesh immediately to the right of the reference mesh is sequentially checked.
It will be.
[0051]
FIG. 5 and FIG. 6 are explanatory diagrams showing the leader line setting process procedure for the outer mesh area of the construction area polygon, and the contents thereof are as follows. The following processing procedure is subsequent to the flag setting process of FIGS. 2 and 3, and it is assumed that all the construction area polygon records used in the flag setting process are held in the work area 32.
[0052]
That is,
(21) Define the following variables anew and go to the next step.
・ K indicates the new record number of the extracted leader
・ T indicating the number of auxiliary line exchanges
(22) All the leader line records relating to the construction area control chart creation target area are extracted from the external storage device 33, and the process proceeds to the next step.
(23) Set the variables n, k, and t as follows and proceed to the next step.
・ "1 → n"
・ "1 → k"
・ "0 → t"
(24) From the leader line records, those whose start point (point A) belongs to the construction area polygon of record number n are extracted, and a new record number is assigned to each, and the process proceeds to the next step. .
(25) F (0,0,0,0) flag indicating the explanation information guide line (B-C point) corresponding to the leader record of the new record number k and the mesh area necessary for describing the explanation information While selecting from the standing range, the flag element s of the selected mesh is set to “1”, and the process proceeds to the next step.
(26) Set an auxiliary line (point A-point B) corresponding to the leader line record, and proceed to the next step. Note that it is arbitrary which intermediate point (point B) is selected in the selected mesh, that is, which part of the explanation information guide line 13 is connected to the auxiliary line is arbitrary.
(27) Determine whether or not the processing for all leader records extracted in step (24) has been completed.If `` YES '', proceed to step (29); if `` NO '', proceed to the next step. move on.
(28) Return to step (25) as “k + 1 → k”.
(29) It is determined whether or not there is a leader line where the auxiliary lines intersect. If “YES”, the process proceeds to the next step, and if “NO”, the process proceeds to step (33). The leader line to be judged at this time belongs to the construction area polygon of the record number n that is currently being processed.
(30) It is determined whether or not “t ≧ 10”. If “YES”, the process proceeds to step (33), and if “NO”, the process proceeds to the next step. This determination process is for advancing the leader line setting process to the next step when the intersection state of the auxiliary lines is not resolved even if the auxiliary line exchange in step (31) is repeated a predetermined number of times. "Is just an example of a predetermined number of times.
(31) For each set of intersecting leader lines, a new auxiliary line that replaces the starting point, that is, a new auxiliary line that connects the intermediate point of the original auxiliary line and the starting point of the opponent auxiliary line. After setting, go to the next step.
(32) As “t + 1 → t”, the process returns to the step (29).
(33) Judge whether or not the processing for all construction area polygon records in the creation target area has been completed. If "YES", the leader line setting process ends. If "NO", proceed to the next step. .
(34) As “n + 1 → n”, the process returns to the step (24).
[0053]
Here, in selecting the mesh region in step (25), for example,
・ Draw a straight line from the start point (point A) of the leader line record that has a predetermined range of angles and does not pass through other construction area polygons.
-A mesh in the horizontal direction (parallel to the X axis) intersecting with a predetermined range portion of the straight line with the flag F (0,0,0,0) is selected.
[0054]
It should be noted that the circle surrounding the road number described in the road drawing is also processed as a construction area polygon so that explanation information or the like is not displayed on the circle.
[0055]
The construction area polygon in this case is
・ Polygon in the shape of a circle represented by a short vector
・ Square polygon circumscribing the circle
Etc. are used.
[0056]
【The invention's effect】
In this way, the present invention makes the setting range of the explanation information about the construction area the entire outside part of the construction area polygon, avoids at least the overlap of the display area of the explanation information, and the auxiliary line part of the leader line. The number of intersections is reduced.
[0057]
Furthermore, the construction area control chart creation target area is divided into a plurality of meshes, and a leader line flag is set in the mesh part used for the description of description information, etc., to prevent duplicate descriptions in the mesh. Therefore, it is possible to provide a construction area management chart in which leader lines and explanation information related to the construction area are written in a concise and easy-to-read form, and the convenience can be enhanced.
