The building shown in FIG. 3 includes rooms R1 to R3. The plan view is an example of the second drawing. A design drawing or the like may be used instead of the plan view. In that case, the plan view DB 111 stores design drawings of the target building and the like.

From the facility drawing, it is possible to read the shapes of the devices that make up the facility, the positions where the devices are arranged with reference to the reference point O, and connection information between devices such as pipes and electrical wiring that connect the devices. Also, the position where the facility is arranged can be read from the information indicating the floor plan of the building described in the area other than the facility in the facility drawing. The facility drawing is an example of the first drawing.

As a typical example of the conversion processing by the information processing apparatus 100, a case of reading a diagram relating to facilities installed in a building and converting it into electronic data will be described below. In such a case, when extracting the location of the facility and the connection information such as piping and electrical wiring that connects the facilities from the facility drawing, the information of the floor plan showing the building is the extraction result. can affect According to the information extraction processing of the embodiments described below, the above effects can be reduced.

(Information extraction processing)
Information extraction processing by the information processing apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 6 is a flow chart showing the procedure of information extraction processing according to the embodiment.

In order to simplify the explanation of the information extraction process below, each drawing, which is a printed matter, is a two-dimensional drawing (2D drawing). Assume that It should be noted that conversion of different scales to the same scale and alignment of the position of the reference with respect to the building are not limited, and may be carried out by known methods as appropriate.

First, the designated position acquisition unit 121 acquires information designating a predetermined position to be subjected to information extraction processing. The image acquiring unit 122 acquires the plan view of the designated position from the plan view DB 111, and similarly acquires the facility drawing from the facility drawing DB 112 (step S10).

Next, the facility extracting unit 123 deletes the portion described in the plan view from the description of the facility drawing (step S20), and generates a drawing of the target facility from the difference information remaining after the deletion. For example, the lines of the outer wall OW and inner wall IW of a building are often described in both the floor plan and the facility drawing. Here, by deleting the parts described in the plan view from the description in the facility drawing, it is possible to leave the information about the facility.

Next, the correction processing unit 124 repairs the drawing in which the portion described in the plan view is deleted from the description of the facility drawing (step S30). Details of the repair method will be described later.

Next, the conversion processing control unit 126 applies a pattern matching method for matching with the outline drawing stored in the reference model DB 114 to the drawing after repair, and converts the drawing of the facility included in the drawing after repair. It extracts and records the drawing related to the facility drawing in the layout DB 113 (step S40).

For example, in the pattern matching process for matching with the outline drawing in step S40, the outline drawing stored in the reference model DB 114 is divided for each type of facility, and the predetermined The outline drawing included in the range of is targeted for identification. When there is an area that matches the outline of the outline drawing in the above pattern matching process, the conversion processing control unit 126 determines that the facility of the outline drawing is placed in that area. The conversion processing control unit 126 sets the type of the facility arranged at that position to the type information of the facility assigned to the outline drawing. The conversion processing control unit 126 sequentially switches the outline drawings stored in the reference model DB 114, and repeats this until collation of all outline drawings to be identified is completed.

Next, the output processing unit 127 outputs the collation result (step S50). For example, the output processing unit 127 regards, among the extracted drawings, descriptions for which the outer shape is determined to match based on the result of the collation as collated facilities based on the reference model DB 114 . On the other hand, among the extracted drawings, descriptions for which it is determined that the outer shape does not match are regarded as unmatchable portions. The output processing unit 127 adds the collated equipment to the equipment list and sets the display in the drawing to the first display. The output processing unit 127 changes the display in the drawing to the second display for the portion that cannot be collated.

For example, the output processing unit 127 makes the colors of the first display and the colors of the second display different from each other. The first display color may be black and the second display color may be red. As a result, it is possible to easily identify a portion of the extracted drawing that has been determined to have a non-matching outline.

Through the series of processes described above, information about facilities can be extracted from the facility drawing.

(Treatment of Repairing Drawings)
Here, the process of repairing the drawing in step S30 will be described. FIG. 7 is a diagram for explaining processing for repairing a drawing according to the embodiment.

FIG. 7(a) shows a part of the facility drawing. FIG. 7(c) shows a plan view F2 of the range corresponding to the facility drawing shown in FIG. 7(a). FIGS. 7(b) and 7(d) to 7(g) show diagrams generated in the course of conversion processing based on the facility diagram shown in FIG. 7(a).

The facility drawing F1 shown in FIG. 7A describes the inner wall IW, the pipe LD1, and information TP1 indicating the type (D30A) of the pipe LD1. For example, it is assumed that the pipe LD1 passes through the inner wall IW vertically. If this is expressed in a facility drawing, it will be a drawing in which the inner wall IW and the pipe LD1 intersect each other in a straight section.

The facility extraction unit 123 extracts lines or line segments from the facility drawing F1 shown in FIG. 7(a), for example, by performing a predetermined filter process for deleting characters, numbers, and the like. The result is shown in the equipment drawing F11 of FIG.7(b).

The plan view F2 shown in FIG. 7(c) shows the inner wall IW, but does not show the pipe LD1. The equipment extraction unit 123 deletes the description of the plan view F2 shown in FIG. 7(c) from the equipment drawing F11 shown in FIG. 7(b). The result is shown in the equipment drawing F3 of FIG.7(d).

If it is mechanically deleted as described above, the piping LD1 included in the facility drawing F11 may be divided into the piping LD11 and the piping LD12 as shown in the facility drawing F3. In other words, as a result of the lack of part of the information on the continuous pipe LD1, the pipe LD11 and the pipe LD12 are separated in the facility drawing F3, and the connection destination information indicated by the pipe LD1 is missing.

Therefore, the correction processing unit 124 compensates for the missing portion of the pipe LD1 in the facility drawing F3, and restores the information of the pipe LD1 by the method illustrated below.

First, the correction processing unit 124 extracts the pipe LD11 from the facility drawing F3. This extraction extracts the location where the line is broken from the difference information between the facility drawing F11 and the facility drawing F3, and sets one of them as the pipe LD11 and the other as the pipe LD12. Here, the correction processing unit 124 defines an installation drawing F31 that includes the piping LD11 but does not include the piping LD12, and an installation drawing F32 that does not include the piping LD11 but includes the piping LD12.

The correction processing unit 124 generates an extension pipe LD11A by extending the pipe LD11 in the extension direction in the installation drawing F31. Similarly, in the facility drawing F32, an extension pipe LD12A is generated by extending the pipe LD12 in the extending direction.

Next, when the facility drawing F31 and the facility drawing F32 are overlapped, there is a range where the respective extension pipes LD11A and extension pipes LD12A overlap. The correction processing unit 124 regards the overlapping range as a part of the piping LD1 of our office, generates the piping LD1R connecting the piping LD11 and the piping LD12, and generates the facility drawing F4. As a result, in the facility drawing F4, based on the piping LD11 and the piping LD12, the missing portions in the facility drawing F3 are compensated for and repaired by the continuous piping LD1R.

By performing such a drawing repair process, it is possible to increase the identification rate of collation of outline drawings performed later, and the identification rate of pipes, wiring, etc., penetrating the inner wall IW.

As shown in the above embodiment, the facility extraction unit 123 in the information processing apparatus 100 includes a facility diagram in which at least the design of the building and target facilities are drawn, and a facility diagram in which at least the design of the building is drawn and the target Based on the plan view of the building where the facilities are not drawn, difference information between the facility plan and the plan view is extracted, and the plan of the target facility is generated from the difference information. As a result, the information processing apparatus 100 can, at least from the facility diagram without electronic data, convert the information of the facility described in the facility diagram into data.

Further, the correction processing unit 124 generates an equipment diagram by interpolating a portion where the information regarding the target equipment is missing due to the extraction of the difference information by the equipment extraction unit 123 based on the extracted difference information. As a result, even if the information of the equipment described in the equipment drawing is missing due to the above extraction, the information processing apparatus 100 can fill in the missing part of the information and convert it into data.

Further, the correction processing unit 124 divides the extracted difference information of the piping part into the piping LD11 (first difference information) and the piping LD12 (second difference information) across the missing part in the predetermined plane. By complementing the missing part so as to connect the pipe LD11 and the pipe LD12, the missing part is compensated for by the process of extracting the difference information between the equipment drawing and the plan view, and the equipment information in the equipment drawing can be played.

Further, by extracting the target facility using the data indicating the shape of the target facility, the facility described in the facility drawing can be identified. For example, the information processing apparatus 100 can read a diagram of equipment described in a two-dimensional drawing such as a diagram of equipment with desired accuracy. Unlike simply reading an image electronically, the computer of the information processing apparatus 100 can obtain attribute information that can be used by CAD software or the like.

(First modification)
A first modification of the embodiment will be described. In this first modified example, another example of repairing a portion where a straight line that should be continuous among pipes or wires extracted in step S30 is cut will be described.

FIG. 8 is a diagram for explaining processing for repairing a drawing according to the first modification.
FIG. 8(a) shows a part of the facility drawing. FIG. 8(b) shows a plan view F2 of the range corresponding to the facility drawing shown in FIG. 8(a). The diagram of FIG. 8(c) shows a diagram generated by conversion processing based on the plan view shown in FIG. 8(b). The diagram of FIG. 8(d) is a diagram generated by conversion processing based on the facility diagram shown in FIG. 8(a).

The facility drawing F1 shown in FIG. 8A describes the inner wall IW, the pipe LD1, and information TP1 indicating the type (D30A) of the pipe LD1. For example, it is assumed that the pipe LD1 passes through the inner wall IW vertically. Expressing this in terms of equipment, the inner wall IW and the pipe LD1 intersect each other in a straight section.

Plan view F2 shown in FIG. 8B shows inner wall IW with thickness W1, but does not show pipe LD1.

For example, comparing the inner wall IW of the facility drawing F1 shown in FIG. 8A with the inner wall IW of the plan view F2 shown in FIG. Therefore, the following events may occur.

- Even if the position of the drawing is adjusted with reference to the reference point O, the position of the inner wall IW is displaced in the direction intersecting the extending direction of the inner wall IW.
- The thickness of the inner wall IW is different.
- The thickness of the line that draws the inner wall IW is different.

When the above phenomenon occurs, even if the positions of the facility drawing F1 and the plan view F2 are aligned with the reference point O as a reference and overlapped, the lines of the inner wall IW and the like may not overlap.

Therefore, in this modification, the correction processing unit 124 converts the inner wall IW of the plan view F2 shown in FIG. 8B into a thickness W2 around the center of the wall to create a plan view F21.

The correction processing unit 124 deletes the description of the plan view F21 shown in FIG. 8(c) from the facility drawing F1 shown in FIG. 8(a). The result is shown in the equipment drawing F3 of FIG.8(d). Due to the above deletion, the piping LD1 included in the facility drawing F11 is divided into the piping LD11 and the piping LD12 as shown in the facility drawing F3.

As described above, the correction processing unit 124 may apply the technique of the embodiment to repair the part where the pipe LD11 and the pipe LD12 are separated.

According to the above modification, by extracting the difference information after thickening the lines drawn on the plan view (second drawing), the parts common to the facility drawing F1 and the plan view F2 are different at the drawing stage. Even if there is, the inner wall IW, the outer wall OW, etc. can be deleted without omission by widening the range to be deleted.

Instead of converting the thickness of the inner wall IW, conversion processing may be performed to increase the width of the lines in the plan view F21. In this case, the correction processing unit 124, for example, creates a plan view F21 in which the widths of the lines indicating the inner wall IW are thickened based on the center of each line. The width of the line may be determined according to the size of the positional deviation between the line of the facility drawing F1 and the line of the plan view F2. Other processing may be the same as the processing of the embodiment.

(Second modification)
A second modification of the embodiment will be described. In this second modified example, an example of extracting written characters and numbers from an equipment drawing will be described.

FIG. 9 is a diagram for explaining processing for extracting characters and numbers according to the second modification. FIG. 9(a) shows a part of the facility drawing. FIG. 9(b) shows a plan view F2 of a range corresponding to the facility drawing shown in FIG. 9(a). The diagram of FIG. 9(c) shows a diagram generated by conversion processing based on the facility diagram shown in FIG. 9(a) and the plan view shown in FIG. 9(b). The diagram of FIG. 9(c) corresponds to the diagram of FIG. 7(g) described above. The diagram of FIG. 9(d) is a diagram generated by conversion processing based on the facility diagram shown in FIG. 9(a).

The facility drawing F1 shown in FIG. 9A describes the inner wall IW, the pipe LD1, and information TP1 indicating the type (D30A) of the pipe LD1. The plan view F2 shown in FIG. 9B shows the inner wall IW, but does not show the pipe LD1. In FIG. F4 shown in FIG. 9C, the inner wall IW is not shown, but the pipe LD1R is shown.

The correction processing unit 124 deletes the description of the plan view F2 shown in FIG. 9(c) and the description of the view F4 shown in FIG. 9(c) from the facility drawing F1 shown in FIG. 9(a). The results are shown in F5 of FIG. 9(d). Due to the above deletion, the letters and numbers contained in the facility drawing F11 remain as shown in FIG. F5. The correction processing unit 124 identifies the description of characters and numbers in FIG. F5 by an OCR (Optical Character Recognition/Reader) function.

Note that the correction processing unit 124 writes the descriptions of letters and numbers identified by the above process into a storage area or registers them as facility attribute information in the CAD system so that they can be used to generate new drawings. may

According to the above modification, the information processing apparatus 100 extracts the location of the facility from the facility drawing, and also reads the characters and numbers described in the facility drawing, thereby reducing the burden of inputting the characters and numbers. can be mitigated.

(Third modification)
A third modification of the embodiment will be described. In this third modified example, another example of extracting written characters and numbers from the facility drawing will be described.

FIG. 10 is a diagram for explaining processing for extracting characters and numbers according to the third modification. FIG. 10(a) shows a part of the facility drawing. 10(b) and 10(c) are diagrams generated by conversion processing based on the facility diagram shown in FIG. 10(a).
