  The processing unit 20 includes one or a plurality of processors and their peripheral circuits. The processing unit 20 controls the overall operation of the information processing apparatus 1 and is, for example, a CPU. The processing unit 20 executes processing based on programs (driver program, operating system program, application program, etc.) stored in the storage unit 11. The processing unit 20 can execute a plurality of programs (such as application programs) in parallel.

  The processing unit 20 includes a drawing data acquisition unit 21, a drawing data extraction unit 22, a character string determination unit 23, a drawing data storage unit 24, a processing end determination unit 25, and a drawing data output unit 26.

The character string determination unit 23, the element number determination unit 27, the projection drawing number determination unit 28, the projection drawing position determination unit 29, and the arrangement region determination unit 30 specify drawing data indicating drawing data that satisfies a given condition. Functions as a specific part. The drawing data specifying unit refers to the drawing database 111 storing a plurality of drawing data, includes a character string that is the same as or similar to the extracted character string, and has the same or predetermined difference as the number of the extracted projection drawings. One or a plurality of drawing data including a number of projections within the range of is specified. The drawing data output unit 26 outputs one or a plurality of drawing data specified by the drawing data specifying unit.

(Drawing extraction processing by the information processing apparatus according to the embodiment)
FIG. 2 is a flowchart of the drawing extraction process by the information processing apparatus 1. The drawing extraction process shown in FIG. 2 is executed mainly by the processing unit 20 in cooperation with each element of the information processing apparatus 1 based on a program stored in the storage unit 11 in advance.

  First, the drawing data acquisition unit 21 acquires drawing data indicating a drawing from the storage unit 11 (S101). The drawing data is in the DXF format, the DWG format, and the like, for example, like the plurality of drawing data included in the drawing database 111, and is a format from which various information can be extracted. Drawing data is defined by line information indicating the line segment specified by the coordinates of the start point and end point, circle information indicating the circle specified by the coordinate value and radius value of the center, the center, radius, start point angle, and end point angle. Arc information indicating the arc to be played is included. The drawing data further includes text information indicating text defined by the character string, the character height, the coordinate value of the reference point, and the character position.

  Next, the drawing data extraction unit 22 extracts a character string corresponding to the text information included in the drawing data acquired in the process of S101 (S102). The drawing data extraction unit 22 extracts a character string from text information included in the drawing data acquired in the process of S101. The character string extracted by the process of S102 includes the names of drawings such as “plan view of screw” and “five views of screw”.

  Next, the character string determination unit 23 refers to the drawing database 111 and sets one or a plurality of drawing data including a character string that is the same as or similar to the character string extracted in the process of S102 to a plurality of pieces of data included in the drawing database 111. It is specified from the drawing data (S103). The drawing data storage unit 24 stores the specified one or more drawing data as character string specifying drawing data in the storage unit 11 (S104).

  The character string determination unit 23 refers to text information included in a plurality of drawing data included in the drawing database 111 and determines whether or not the character string includes the same or similar character string as the character string extracted in the process of S102. To do. The character string similarity determination process may be executed using a character string similarity determination technique based on the Levenshtein distance or the like. In one example, in the similarity determination process, when the Levenshtein distance between character strings is equal to or smaller than a predetermined determination threshold, the character string extracted in the process of S102 and a plurality of drawing data included in the drawing database 111 are included. It is determined that the character string included is similar.

  Next, the process end determination unit 25 determines whether or not the number of drawing data specified in the process of S103 is equal to or less than a predetermined threshold (S104). The threshold value is a number that can be checked by a drawing creator who checks the drawing, and is about 5 to 10, for example. When the process end determination unit 25 determines that the number of drawing data specified in the process of S103 is equal to or less than the threshold (S105-YES), the drawing data output unit 26 stores the drawing data specified in the process of S103. It outputs to the output part 13 (S106). The output unit 13 displays a drawing corresponding to the drawing data output from the drawing data output unit 26.

  If the process end determination unit 25 determines that the number of drawing data specified in the process of S103 is greater than the threshold (S105—NO), the process proceeds to S107. That is, it is determined that the number of drawing data included in the first drawing data group including the character string that is the same as or similar to the extracted character string among the plurality of drawing data stored in the storage unit 11 is greater than the threshold value. Then, the process proceeds to S107. The drawing data extraction unit 22 extracts the number of each of the plurality of elements included in the plurality of drawing data acquired in the process of S101 (S107). The drawing data extraction unit 22 extracts the number of each of the plurality of elements from line segment information, circle information, arc information, and the like included in the drawing data acquired in the process of S101. The number of each of the plurality of elements extracted by the process of S107 includes, for example, the number of line segments, circles, and arcs.

  Next, the element number determination unit 27 obtains one or a plurality of drawing data including the number of elements within the same or predetermined difference range as the number of the plurality of elements extracted in the process of S107 by the process of S104. It is specified from the stored character string specifying drawing data (S108). The number-of-elements determination unit 27 extracts the number of each of the plurality of elements from the character string specific drawing data stored in the process of S104 and compares it with the number of elements extracted in the process of S107. Specify drawing data. That is, the element number determination unit 27 extracts the number of each of the plurality of elements included in the drawing data included in the first drawing data group, and is equal to or equal to the predetermined number of the extracted plurality of elements. A second drawing data group including the number of elements within the range of is specified. The drawing data storage unit 24 stores the specified one or more drawing data as element specifying drawing data in the storage unit 11 (S109).

  Next, the process end determination unit 25 determines whether or not the number of drawing data specified in the process of S108 is equal to or less than a threshold value (S110). When the process end determination unit 25 determines that the number of drawing data specified in the process of S110 is equal to or less than the threshold (S110-YES), the drawing data output unit 26 stores the drawing data specified in the process of S108. It outputs to the output part 13 (S106). The output unit 13 displays a drawing corresponding to the drawing data output from the drawing data output unit 26.

  If it is determined that the number of drawing data specified in the process of S108 is greater than the threshold (S110-NO), the process proceeds to S111. That is, if it is determined that the number of drawing data included in the second drawing data group specified in the processing of S108 is greater than the threshold value, the processing proceeds to S111. The drawing data extraction unit 22 converts the coordinates of the elements included in the drawing data acquired in the process of S101 (S111). Specifically, the drawing data extraction unit 22 sets the coordinates of the elements included in the drawing data acquired in the processing of S101 to the same origin as the coordinates that define the elements of the drawing data included in the drawing database 111. Convert to the coordinates you have.

  Next, the drawing data extraction unit 22 estimates a projection drawing area indicating an area in which one or a plurality of projection drawings included in the drawing corresponding to the drawing data whose coordinates have been converted in the processing of S111 is arranged (S112). The drawing data extraction unit 22 determines whether or not the drawing formed by the elements forms a projection based on the distance between the elements such as line segments, circles, arcs, and texts included in the drawing data. Specifically, the drawing data extraction unit 22 presumes that the elements generated by the elements that are in contact with each other and the elements whose distances are equal to or less than a predetermined threshold distance form a single projection. To do. In one example, the threshold distance is 0.1 times the height of the outer frame of the drawing corresponding to the drawing data. The drawing data extraction unit 22 estimates the outer periphery of the projection drawing from the coordinates of the element, and estimates that the drawing generated by the elements included in the region surrounded by the estimated outer periphery is a drawing that forms a single projection drawing. To do. The drawing data extraction unit 22 estimates each of the regions in which the drawings estimated to form a single projection map are described as projection map regions.

  FIG. 3 is a diagram illustrating an example of a drawing corresponding to the drawing data.

  Drawing 300 is a five-side view of a cylindrical object, and includes a front view 301, a plan view 302, a bottom view 303, a right side view 304, and a left side view 305. Each of the front view 301, the right side view 304, and the left side view 305 has a rectangular outer shape formed by four line segments 311 to 314, line segments 341 to 344, and line segments 351 to 354. Each of the plan view 302 and the bottom view 303 has a circular outer shape formed by two circles 321 to 322 and circles 331 to 332.

  The drawing data extraction unit 22 estimates a region surrounded by the outer periphery formed by the four line segments 311 to 314 in contact with the end portions as a projection drawing region of the front view 301. Similarly, the regions surrounded by the outer peripheries formed by the line segments 341 to 344 and the line segments 351 to 354 are estimated as the projected view areas of the right side view 304 and the left side view 305, respectively.

  The drawing data extraction unit 22 estimates a region surrounded by the outer periphery formed by the circle 321 as a projection drawing region of the plan view 302. Similarly, the area surrounded by the outer periphery formed by the circle 331 is estimated as the projection drawing area of the bottom view 303.

  Next, the drawing data extraction unit 22 determines the number of projection map regions estimated in S112 as the number of projection maps included in the drawing corresponding to the drawing data (S113). Since the drawing 300 includes five projection map regions, the drawing data extraction unit 22 determines the number of projection maps to be five. The drawing data extraction unit 22 extracts the number of projections from the drawing data through the processes of S111 to S113.

  Next, the projection map number determination unit 28 stores one or a plurality of drawing data including the number of projection maps within the same or predetermined difference range as the projection map number determined in the process of S113 in the process of S109. The specified element specification drawing data is specified (S114). The projection figure number determination unit 28 extracts the number of projection figures from the element specific drawing data stored in the process of S109, and compares it with the number of projection figures extracted in the processes of S111 to S113. Specify drawing data. That is, the projection drawing number determination unit 28 specifies one or a plurality of drawing data including the number of projection drawings in the second drawing data group that is the same as the number of extracted projection drawings or within a predetermined difference range. To do. The drawing data storage unit 24 stores the specified one or more drawing data in the storage unit 11 as projection drawing number specifying drawing data (S115).

  Next, the process end determination unit 25 determines whether or not the number of drawing data specified in the process of S114 is equal to or less than a threshold value (S116). If the process end determination unit 25 determines that the number of drawing data specified in the process of S114 is equal to or less than the threshold (S116-YES), the drawing data output unit 26 stores the drawing data specified in the process of S116. It outputs to the output part 13 (S106). The output unit 13 displays a drawing corresponding to the drawing data output from the drawing data output unit 26.

  If it is determined that the number of drawing data identified in the process of S112 is greater than the threshold (S116—NO), the process proceeds to S117. The drawing data extraction unit 22 determines the position of the projection diagram included in the drawing corresponding to the drawing data acquired in the process of S101 (S117). For example, the arrangement region determination unit 30 determines the coordinates of the lower left portion of the projection view included in the drawing as the position of the projection view.

  FIG. 4 is a diagram illustrating an example of the position of the projection diagram determined by the drawing data extraction unit 22.

  The drawing data extraction unit 22 determines the coordinates of the lower left portion 401 of the front view 301 as the coordinates of the front view 301, determines the coordinates of the lower left portion 402 of the plan view 302 as the coordinates of the plan view 302, and lower left of the bottom view 303. The coordinates of the part 403 are determined as the coordinates of the bottom view 303. The drawing data extraction unit 22 determines the coordinates of the lower left side 404 of the right side view 304 as the coordinates of the right side view 304, and determines the coordinates of the lower left side 405 of the left side view 305 as the coordinates of the left side view 305. The drawing data extraction unit 22 determines the coordinates of the lower left portion of the projection view included in the drawing as the position of the projection view, but other coordinates such as the coordinates of the upper right portion of the projection view and the coordinates of the center of gravity of the projection view. The coordinates may be determined as the position of the projection view.

  Next, the projection map position determination unit 29 acquires one or a plurality of drawing data including a projection map arranged within the same or predetermined difference range as the projection map position determined in the process of S117 in the process of S115. It is specified from the stored projection figure number specifying drawing data (S118). The projection map position determination unit 29 determines the position of the projection map from the projection map number specifying drawing data stored in the process of S115, and compares it with the position of the projection map determined in the process of S117. Specify drawing data. In other words, the projection map position determination unit 29 specifies the position of the projection map included in the drawing corresponding to the drawing data, and selects the projection map arranged within the same or predetermined difference range as the position of the specified projection map. Identify one or more drawing data to include. The drawing data storage unit 24 stores one or more specified drawing data in the storage unit 11 as c (S119).

  Next, the process end determination unit 25 determines whether or not the number of drawing data specified in the process of S118 is equal to or less than a threshold value (S120). When the process end determination unit 25 determines that the number of drawing data specified in the process of S118 is equal to or less than the threshold (S120-YES), the drawing data output unit 26 stores the drawing data specified in the process of S118. It outputs to the output part 13 (S106). The output unit 13 displays a drawing corresponding to the drawing data output from the drawing data output unit 26.

  If it is determined that the number of drawing data identified in the process of S118 is greater than the threshold (S120—NO), the process proceeds to S121. The drawing data extraction unit 22 determines the position and size of a rectangle that includes the entire drawing corresponding to the drawing data acquired in S101 (S121). Specifically, the drawing data extraction unit 22 determines the coordinates of the lower left vertex and the upper right vertex of a rectangle including the entire drawing.

  FIG. 5 is a diagram illustrating an example of the position of the projection diagram determined by the drawing data extraction unit 22.

  The drawing data extraction unit 22 determines the coordinates of the lower left vertex 501 from the coordinates of the lowest point in the vertical direction of the bottom view 303 and the coordinates of the leftmost point in the horizontal direction of the left side view 305. The drawing data extraction unit 22 determines the coordinates of the upper right vertex 502 from the coordinates of the uppermost point in the vertical direction of the plan view 302 and the coordinates of the rightmost point in the horizontal direction of the left side view 305. Note that the drawing data extraction unit 22 determines the coordinates of the lower left vertex and the upper right vertex of the rectangle including the entire drawing, but the coordinates of the upper left vertex and the upper right vertex of the rectangle including the entire drawing and the rectangle Other coordinates such as the coordinates of the center of gravity may be determined as the position of the projection view.

  Next, the arrangement area determination unit 30 performs one or more drawing data including drawings arranged in an area within the same or predetermined range as the position and size of the rectangle determined in the process of S121 as the process of S119. Is specified from the projection drawing position specifying drawing data stored in (S122). The arrangement region determination unit 30 determines the position and size of the rectangle from the projection drawing position specifying drawing data stored in the process of S119, and compares it with the position and size of the rectangle determined in the process of S122. Identify multiple drawing data. In other words, the arrangement region determination unit 30 identifies the size of the projection diagram included in the drawing corresponding to the drawing data, and selects a projection diagram having the same size as the identified projection diagram or within a predetermined difference range. Identify one or more drawing data to include. Next, the drawing data output unit 26 outputs the drawing data specified in the process of S122 to the output unit 13 (S106).
