Description

  The present invention relates to a CAD information generation system, method and program thereof, and more particularly to a CAD information generation system, method and program for generating CAD information for drawing a structure suitable for a candidate site by a simple operation.

  Conventionally, as one of the sales methods of sales staff in contractors (including contractors, construction companies, and housing sales companies), walking in the sales area in charge, such as vacant lots, idle land, or parking lots There is a work of finding a land suitable for construction such as a new house or a building as a “sale candidate site”. After finding the candidate site, the sales staff returns to the company, obtains a housing map and public maps, etc. of the candidate site, and asks the in-house design staff for a completed forecast map such as a “perth map” of the building to be built at the candidate site. Request creation. The design staff who has received the request creates a completed forecast map suitable for the candidate site by using drawing software such as CAD. Only after the perspective map is completed, the sales staff visits the owner who is the owner of the candidate site with the perspective map and starts the actual sales activities.

  As described above, the conventional sales method requires three stages of work: searching for candidate locations for sales staff, creating perspective diagrams for design staff, and sales activities for sales staff. In addition, searching for a candidate site by a sales staff basically requires walking, so it is very inefficient and cannot always search for a candidate site. There is not enough time for selling to the owner candidate who is the original job for searching for candidate sites, or there is insufficient opportunity for selling due to lack of candidate sites due to inefficiency of searching for candidate sites on foot The situation has been reached. In addition, the design of the building to be constructed in the candidate site requires specialized design staff other than the sales staff, which is also inefficient because it is also the work of a plurality of staff.

  As a CAD system that reduces the labor of the sales staff and supports sales activities, a method called “total presentation system and comprehensive analysis proposing method” (refer to Patent Document 1) has been proposed. However, with this conventional technology, it is possible for a salesman to easily create a house exterior view corresponding to the request of the builder, but it cannot search for a “candidate site”. Therefore, this prior art merely displays a proposal board for a customer in a simple manner, and the task of finding a candidate site that requires the most labor remains imposed on the sales staff. As described above, this conventional technology still lacks functions as a sales activity support system.

<Embodiment 1>
FIG. 1 is a block diagram showing an outline of a CAD information generation system (CIGS) according to an embodiment of the present invention. As shown in the figure, the CIGS 100 includes a control unit (CPU) 110, an input unit 120, an output unit 130, a communication unit 140, a storage unit 150, and a display unit 160. The control unit 110 includes an acquisition unit 111, an operation reception unit 112, and a CAD information generation unit 113. The storage unit 150 stores master CAD information MCI including at least one CAD information corresponding to a partition attribute. The acquisition unit 111 acquires image information captured from the sky or space from the image information providing server IIDS via the communication unit 140 and a network (such as the Internet) NET. The image information is typically digital or analog data of ordinary satellite photographs or aerial photographs, but may be data obtained by processing satellite photographs or aerial photographs by existing image conversion processing or digital conversion processing. Further, it may be a combination of shape data and coordinate data capable of drawing a structure, a ground surface, or a section on the ground. Under the control of the control unit 110, the acquired image information is converted into drawing data to be displayed as a bird's-eye view by a graphic engine (not shown) provided by the system or by an external server. The display unit 160 displays an overhead view using drawing data obtained based on the image information.

  The user observes the bird's-eye view displayed on the display unit 160 and uses his own vision, that is, the shape identification / image identification / analysis ability of a human, so that a new region is displayed in the region shown in the bird's-eye view. Search for parts suitable for the installation or construction of simple structures (buildings, etc.), such as vacant lots, parking lots, old buildings, areas with only simple buildings, etc., and at least 3 to determine the found part (candidate site) Point or more, usually four or more coordinates are indicated with the mouse MUS. Of course, the coordinate instruction may continuously input all the contours of the sections. Currently, high-resolution image information is available via the Internet, so just by observing the bird's-eye view displayed on the display unit 160 of this system, the sales staff as users can walk around and become candidates. It is possible to search for a desired candidate site as if searching for a place. Upon receiving an instruction from the mouse MUS (coordinate pointing device), the operation receiving unit 112 is suitable for installation or construction of a new structure (building or the like) in the region shown in the overhead view via the input unit 120. An operation input that designates the specified part as a designated section is received.

  The CAD information generation unit 113 refers to the master CAD information MCI stored in the storage unit 150, and draws a structure that is allowed to be installed or constructed in the designated section based on the designated section. Information (such as a three-dimensional model) may be generated (one of a plurality of CAD information included in the master CAD information MCI may be selected and used as it is, or may be generated by customizing it). Alternatively, the CAD information may be generated based on the section attribute according to the CAD information construction rule stored in the storage unit.), And the structure drawn based on the CAD information is arranged and displayed on the designated section of the overhead view Display on the unit 160. It is preferable that the CAD information generation unit 113 generates CAD information in which a structure is arranged so that the structure fits inside the designated section. In addition, when the orientation information of the designated section is obtained, a certain installation / structure composition rule (for example, a known housing design method) included in the CAD information construction rule stored in the storage unit in consideration of the orientation of the designated section. According to the rules, install the living room facing south as much as possible, install a toilet in the northeast, install a garden as far south as possible, and move the building to the north.) Determine the installation position. Of course, the arrangement of a new structure in the designated area can be manually designated by the user with a position pointing device such as a mouse MUS. The CAD information generation unit 113 uses a specified interference area (for example, 1 m from the boundary as the interference area) stored in the storage unit. Depending on the area such as a big city, the interference area may be reduced to the limit of construction. In consideration of the above, it is preferable to generate CAD information such that the structure is arranged as far as possible on the north side of the designated section, and the windows are arranged on the south side in consideration of daylighting. Further, when road marking information (road setting information on a designated section) is obtained, the CAD information generation unit 113 sets a specified interference area (for example, 1 m from the road as the interference area) stored in the storage unit. ), It is preferable to generate CAD information (design information used in a computer capable of drawing the structure) such that the entrance of the structure is arranged on the road side.

  It is possible to send the generated CAD information and intermediate data and acquired data to the outside, display them on the display unit, store the generated information, intermediate data and acquired data, etc. in the storage unit, It should be noted that other actual modes described later are possible as well. The system (apparatus) is a general-purpose computer, a special-purpose computer, a server, a PC, or the like, or a program module that realizes (executes) the function and processing procedure (method) of the system on the computer. It is preferable to construct this system on a computer by holding it in a CPU or storage unit of the computer or by reading it from an external server or storage, and the same applies to the embodiments described later.

  FIG. 2 is a flowchart showing an example of processing executed in the system shown in FIG. As shown in the figure, in step S11, the acquisition unit 111 uses the communication unit 140 to obtain image information (aerial photograph) taken from the sky or the space from a flying object such as an aircraft or an artificial satellite by an imaging device such as a camera. Information such as satellite photos) via a network (such as the Internet). The display unit 160 displays an overhead view based on the image information. Next, in step S12, the operation reception unit 112 has a portion (for example, a vacant lot, a parking lot, and a simple building) suitable for installation or construction of a new structure (building or the like) in the area shown in the overhead view. An operation input that designates a designated area as a designated section is received. In step S13, the storage unit 150 generates CAD information of different structures for each section attribute (for example, three-dimensional model information for generating three-dimensional modeling corresponding to the section), or section attributes, that is, Master CAD information MCI including a plurality of CAD information corresponding to a pattern (shape or site area) is stored. In step S14, the CAD information generation unit 113 refers to the master CAD information MCI, and based on the designated section, CAD information for drawing a structure that is allowed to be installed or constructed in the designated section (for example, 3D model) is generated. Finally, in step S15, the CAD information generation unit 113 arranges the structure drawn based on the CAD information on the designated section of the overhead view and causes the display unit 160 to display the structure.

  FIG. 3 is an explanatory diagram for explaining processing by the CIGS 100 shown in FIG. As shown in the figure, the overhead view OV1 is an image itself drawn based on image information acquired from the image information providing server IIDS. In the overhead view OV1, the existing building KT1 can be observed. The user (sales staff, etc.) is suitable for installing or constructing a new structure (building, etc.) in the area shown in the overhead view by scrolling the overhead view OV1 up, down, left and right (ie, east, west, north, south). A part (for example, a vacant lot, a parking lot, an area having only a simple building, etc.) is designated as a designated section. This designation is accepted by the system as an operation input. In this case, a rectangular section is designated as the designated section SS1 by clicking four points of the points A, B, C, and D with the mouse. Then, the system generates CAD information for drawing the structure SO1 based on the attribute of the section (such as the rectangular shape of the section and the aspect ratio). Preferably, the section attributes include scale information added to the image information or separately acquired from the image information providing server IIDS. This CAD information may be only the appearance of a building such as a three-dimensional house or building, but also the interior room layout, furniture and fittings (such as cupboards, doors, partitions, window frames, window glass, etc.) It is suitable to include. Finally, the CAD information generation unit arranges the structure SO1 drawn based on the generated CAD information on the designated section SS1 of the overhead view and causes the display unit 160 to display the structure SO1.

  FIG. 4 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV1 is converted into the overhead view OV1m by the processing by the CIGS 100. In the overhead view OV1m, the “structure SO1” is arranged on the designated section SS1. In this way, according to CIGS 100, it is possible to provide an overhead view that displays a structure that has been customized according to the attributes of a designated section, by an extremely simple operation of designating a desired section. . In this example, a plan view of the structure is displayed. However, based on the generated CAD information, a three-dimensional structure, that is, a perspective view (perspective view), an indoor perspective view, or the like can be displayed. .

<Embodiment 2>
FIG. 5 is a block diagram showing an outline of a CAD information generation system (CIGS) according to an embodiment of the present invention. As illustrated, the CIGS 200 includes a control unit (CPU) 210, an input unit 220, an output unit 230, a communication unit 240, a storage unit 250, and a display unit 260. The control unit 210 includes an acquisition unit 211, an operation reception unit 212, and a CAD information generation unit 213. The storage unit 250 stores master CAD information MCI including at least one CAD information corresponding to the attribute of the section, and further includes at least one building restriction information CLI (for example, building coverage ratio, floor area ratio, building use restriction (first (Tanenaka high-rise residential area, etc.), building height restriction information, oblique line restriction information (information such as road oblique line, adjacent oblique line, north side oblique line), shade regulation information, road condition information such as front road). When the latest building restriction information is stored in the public information providing server PIDS, the obtaining unit 211 obtains the information via the communication unit 240 and the network NET, and uses the information as it is to consider the building restriction. It is preferable to generate the prepared CAD information or update the building restriction information CLI in the storage unit 250 to prepare for subsequent use. In the present embodiment, components having the same names as those in the previous embodiments have the same functions as those in the above-described actual aspects and perform the same processing unless otherwise specified. Therefore, the functions and processes having the already-described embodiments and changes are mainly described. It should be noted that this is the same in the following embodiments. The CAD information generation unit 213 further refers to the building restriction information CLI and, based on the designated section, CAD information (for example, a three-dimensional model) for drawing a structure that is allowed to be installed or constructed in the designated section. The structure generated and drawn based on the CAD information is arranged on the designated section of the overhead view and displayed on the display unit 260.

  FIG. 6 is a flowchart showing an example of processing executed in the system shown in FIG. Processing different from the processing described in the first embodiment will be mainly described. That is, description of the processing of steps S21 and S22 is omitted. As shown in the figure, in step S23, the storage unit generates CAD information of different structures for each section attribute, or a plurality of CAD corresponding to section attributes, that is, patterns (shape and site area). The master CAD information MCI including information and “building restriction information” (the details will be described later) are stored. In step S24, the CAD information generation unit 213 refers to the master CAD information MCI and the “building restriction information CLI” and creates a structure that is allowed to be installed or constructed in the designated section based on the designated section. CAD information (for example, a three-dimensional model) to be drawn is generated. Finally, in step S25, the CAD information generation unit 213 arranges the structure drawn based on the CAD information on the designated section of the overhead view and causes the display unit 260 to display the structure.

  The building restriction information stored in the building restriction information CLI includes, for example, building coverage ratio, floor area ratio, building use restriction (first-class / high-rise residential area, commercial area (in the case of a commercial area, the building coverage ratio is 80%)), These include building height restriction information, oblique line restriction information (information such as road oblique lines, adjacent oblique lines, and north oblique lines), shadow regulation information, road condition information such as front roads, and the like. For example, in the case of a candidate site (designated section) for a residential area, the default value can be set as a building coverage ratio of 30% and a volume ratio of 60%. In the case of a candidate site (designated section) for a commercial area, for example, it can be determined that the building coverage ratio is 100% and the volume ratio is 400%. In addition, in order to obtain CAD coordinates of an accurate and exemplary structure by strictly applying the building restriction information, “latitude and longitude” or “address” and “element / item of building restriction information” Are preferably associated with each other. For example, east longitude 139 degrees 44 minutes xx seconds, north latitude 35 degrees 39 minutes xx seconds (or Shinjuku-ku Yotsuya x chome) is a commercial area, or a building coverage ratio of 60%, a floor area ratio of 200%, and a height of 10 meters or more If the building restriction information specified as “Yes” is stored, by referring to this information, it is possible to obtain the exact building restriction information of the section from the coordinates or address of the designated section of the overhead view. Accordingly, it is possible to generate CAD information for drawing a structure that is more matched with the attribute of the designated section. Use a position pointing device such as a mouse to specify a block adjacent to the specified block, a nearby block (peripheral block), or an existing building in the block, and estimate the occupancy rate of the surrounding block based on these area specification information (The estimated occupancy rate can be calculated by “the area of the existing building / the area of the subdivision”. If the average value of a plurality of subdivisions is obtained, the accuracy will be higher.) It is also possible to store it in the building restriction information CLI and use it as building restriction information.

  FIG. 7 is an explanatory view for explaining processing by CIGS 200 shown in FIG. As shown in the figure, the bird's-eye view OV2 is an image itself drawn based on the image information acquired from the image information providing server IIDS without performing special processing. In the overhead view OV2, the existing building KT2 can be observed. The user (sales staff, etc.) is suitable for installing or constructing a new structure (building, etc.) in the area shown in the overhead view by scrolling the overhead view OV2 up, down, left and right (ie, east, west, south, and north). The part (in this example, “vacant land”) is designated as the designated section. This designation is accepted by the system as an operation input. In this case, a rectangular section is designated as the designated section SS2 by clicking four points of the points A, B, C, and D with the mouse. Then, the system generates CAD information for drawing the structure SO2 based on the attribute of the section (such as the rectangular shape of the section and the aspect ratio). Here, it was corrected based on the “building coverage ratio” which is one element of the building restriction information (that is, the maximum restriction value (for example, 6/10 or less) obtained by dividing the building area occupied by the structure by the site area). The correction CAD information for generating the structure SO2-r is generated. Although there are various methods for applying the building coverage ratio, for example, the area of the designated section is not essential, and the number of dots obtained by multiplying the number of dots of the designated section in the overhead view by the building coverage ratio is the site. What is necessary is just to produce | generate the CAD information of a thing. Finally, the CAD information generation unit arranges the structure SO2-r drawn based on the corrected CAD information on the designated section SS2 of the overhead view and causes the display unit 260 to display the structure SO2-r.

  FIG. 8 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV2 is converted into the overhead view OV2m by the processing by the CIGS 200. In the overhead view OV2m, the “structure SO2-r” is arranged on the designated section SS2. In this way, according to CIGS 200, a bird's-eye view that displays a customized structure according to the shape and occupancy rate that are the attributes of the designated section is provided only by an extremely simple operation of designating a desired section. Is possible. In this example, a plan view of the structure is displayed. However, based on the generated CAD information, a three-dimensional structure, that is, a perspective view (perspective view), an indoor perspective view, or the like can be displayed. . Moreover, an acquisition part further acquires the three-dimensional information (3D model) of the existing building (for example, existing building KT2) included in the said bird's-eye view displayed by a display part via a network, and a display part of an existing building The image information including a stereoscopic view based on the stereoscopic information and an overhead view may be displayed.

  FIG. 9 is an explanatory view for explaining processing by CIGS 200 shown in FIG. As shown in the figure, the designated section SS2 is the same as that shown in FIGS. The system once generates three-dimensional CAD information for drawing the structure SO2-x based on the attributes of the sections (such as the rectangular shape of the sections and the aspect ratio). Furthermore, this system is CAD information for drawing the structure SO2-x based on the “volume ratio” (that is, the ratio of the total building area (total floor) to the site area) which is one element of the building restriction information. Is corrected, and CAD information for drawing the structure SO2-x1 is generated. Here, in order to apply the floor area ratio, the area of the designated section is not essential. For example, the structure of the structure assumed according to the number of dots obtained by multiplying the number of dots of the designated section in the overhead view by the floor area ratio. CAD information may be generated. Finally, the CAD information generation unit arranges the structure SO2-x1 drawn based on the corrected CAD information on the designated section SS2 of the overhead view and causes the display unit 260 to display the structure SO2-x1. In this example, since the volume ratio to be applied to the designated section is larger than the default floor ratio, CAD information for drawing a four-story structure having a larger total floor area is obtained.

  FIG. 10 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV2 is converted into the overhead view OV2m1 by the processing by the CIGS 200. In the overhead view OV2m1, “structure SO2-x1” is arranged on the designated section SS2. In this way, according to CIGS 200, an overhead view that displays a structure customized according to the shape, the volume ratio, and the like, which are attributes of the designated section, only by an extremely simple operation of designating a desired section. It is possible to provide. In this example, a three-dimensional figure showing a simple appearance of the structure is displayed, but based on the generated CAD information, a more detailed perspective view (perspective view), indoor perspective view, etc. can be displayed. .

  FIG. 11 is a flowchart illustrating an example of processing executed in the system illustrated in FIG. In this embodiment, the three-dimensional information of the existing building (structure) is acquired, and the three-dimensional map of the new structure and the three-dimensional map of the existing building are displayed together with the CAD information generated by this system. As a result, the user can be reminded of a more realistic completed state in the area, and the value of the output drawing as sales support information is increased. Also, normalize (orthorectify) the designated section on the overhead view with a known geometric technique (that is, obtain a normalized section (orthorected image) that allows the section to be viewed vertically from an infinite zenith) Since the site area is calculated from the scale information, CAD information for drawing a more appropriate structure can be generated. Processing different from the processing of the flowchart described above will be mainly described. That is, the description of the process in step S33 is omitted. As shown in the figure, at step S31, the acquisition unit 211 uses the communication unit 240 to acquire image information taken from the sky or space and three-dimensional information of an existing building via a network. The display unit 260 displays an overhead view based on the image information and the three-dimensional information of the existing building. Next, in step 32, the operation reception part 212 receives the operation input which designates the part suitable for installation or construction of a new structure (building etc.) among the area | region shown by the bird's-eye view as a designated division. In this example, since the existing building is three-dimensionally displayed, there is an advantage that the user can easily find the candidate site. In step S34, the designated section on the overhead view is normalized (ie, orthorectified) by a known geometric technique. In step S35, the CAD information generation unit 213 calculates the site area from the scale information acquired together with the image information and the normalized designated section information, and refers to the master CAD information MCI to determine the site area and the normalized designated section information. Based on the attribute of the designated section including the shape, CAD information for drawing a structure that is allowed to be installed or constructed in the designated section is generated. Finally, in step S36, the CAD information generation unit 213 arranges the structure drawn based on the CAD information on the designated section of the overhead view and causes the display unit 260 to display the structure.

  FIG. 12 is an explanatory view for explaining processing by CIGS 200 shown in FIG. As shown in the figure, the overhead view OV3 is drawn from a 3D model of an existing building (structure) acquired via a network in addition to the image itself drawn based on the image information acquired from the image information providing server IIDS. The three-dimensional map of the existing building is also displayed. The user (sales staff, etc.) is suitable for installing or constructing a new structure (building, etc.) in the area shown in the overhead view by scrolling the overhead view OV1 up, down, left and right (ie, east, west, north, south). A part (for example, a vacant lot, a parking lot, an area having only a simple building, etc.) is designated as a designated section. This designation is accepted by the system as an operation input. In this case, a rectangular section is designated as the designated section SS3 by clicking four points of the points A, B, C, and D with the mouse. Incidentally, since a fence-like three-dimensional object can be observed between A-B and D-C, the user can easily determine visually that the designated section SS3 is an independent vacant land. Then, the CAD information generation unit converts the designated section SS3 into a normalized section (that is, an orthoimage) by performing an orthorectification process. Further, the CAD information generation unit generates CAD information for drawing the structure SO3 based on the attribute of the section including the shape of the converted normalized section SS3-r and the site area, and the structure SO3 based on the generated CAD information. Is arranged on the normalized section SS3-r in the overhead view, and finally the three-dimensionally displayed structure SO3-c is arranged in the designated section SS3 and displayed on the display unit 160. By performing processing in this way, it is possible to display a structure that matches the situation of the viewpoint of the overhead view OV3, and it is possible to provide a more realistic completed scene of the building.

  FIG. 13 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV3 is converted into the overhead view OV3m by the processing by the CIGS 200. In the overhead view OV3m, “structure SO3-c” displayed in three dimensions on the designated section SS3 is arranged. In this way, according to CIGS 200, an overhead view displaying a more appropriately customized structure is provided by normalizing the designated section only by an extremely simple operation of designating a desired section. It is possible. In this example, a three-dimensional figure showing a simple appearance of the structure is displayed, but based on the generated CAD information, a perspective view (perspective view) depicting a window or a roof in more detail, an indoor perspective view, etc. are displayed. It is also possible to do.

<Embodiment 3>
FIG. 14 is a block diagram showing an outline of a CAD information generation system (CIGS) according to an embodiment of the present invention. As illustrated, the CIGS 300 includes a control unit (CPU) 310, an input unit 320, an output unit 330, a communication unit 340, a storage unit 350, and a display unit 360. The control unit 310 includes an acquisition unit 311, an operation reception unit 312, and a CAD information generation unit 313. The storage unit 350 stores master CAD information MCI including at least one CAD information corresponding to the attribute of the section, and at least one building restriction information CLI, and further, coordinates (for example, latitude and longitude) and an address (for example, xx). Address information AI associated with city yy town z chome y address, etc.) is stored. In addition, the acquisition unit 311 controls the communication unit 340 to register the registration information providing server RIDS or the public information providing server PIDS via the network NET based on the address (not the complete address, but any level). Registration information and public information (for example, public maps as public maps, textures, land use, oblique line regulation, building height restriction, building coverage ratio, floor area ratio, etc.) can be acquired. The acquired public information may be used as building restriction information to generate CAD information. In particular, when a public map is obtained, it is possible to generate CAD information for generating a structure that accurately applies oblique line regulation, for example, north side oblique line regulation, because the adjacent land and road attachment are known in detail. It becomes.

  FIG. 15 is a flowchart illustrating an example of processing executed in the system illustrated in FIG. Processing different from the processing of the embodiment already described will be mainly described. That is, the description of the process in step S41 is omitted. As shown in the figure, in step S42, the operation accepting unit 312 accepts an operation input for designating a designated section. In this embodiment, it is only necessary to obtain arbitrary coordinates where the designated section is located, and therefore it is not necessary to designate the four vertices of the rectangle as in the first embodiment. Therefore, the user can designate the designated section by simply clicking an arbitrary point including the desired area with the mouse. In step S43, the storage unit stores master CAD information MCI, building restriction information CLI, and “address information AI”. In step S44, the address is obtained from the coordinates of the designated section with reference to the address information. In step S45, the acquisition unit 311 acquires registration information corresponding to the obtained address (typical registration information is a land area, a use area, a site area, and the like). For example, when a use area is included in the acquired registration information, it is possible to obtain a building coverage ratio, a floor area ratio, and the like of the address by referring to the building restriction information. In step S46, the CAD information generation unit 313 refers to the building restriction information and draws a structure that is allowed to be installed or constructed in the designated section based on the section attribute including the registration information. CAD information is generated. Finally, in step S47, the CAD information generation unit 313 arranges the structure drawn based on the CAD information on the designated section of the overhead view and causes the display unit 360 to display the structure.

  FIG. 16 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV4 is converted into the overhead view OV4m by the processing by the CIGS 300. In the overhead view OV4m, the “structure SO4” is arranged on the designated section SS4. Thus, according to CIGS300, the overhead view which displayed the structure customized according to the attribute of the designated division including a part of registration information only by very simple operation of designating a desired division is displayed. It is possible to provide. In this example, a plan view of the structure is displayed. However, based on the generated CAD information, a three-dimensional structure, that is, a perspective view (perspective view), an indoor perspective view, or the like can be displayed. .

  FIG. 17 is a flowchart illustrating an example of processing executed by the system illustrated in FIG. In this example, a process in the case where an operation input for a viewpoint change request has been received after a structure according to the present system has already been arranged and displayed in an overhead view will be described. As shown in the figure, in step S51, the operation reception unit 312 determines whether or not an operation input for a designation change request has been received. The user inputs a designation change request operation by clicking the viewpoint change request point SV in FIG. 18 with a mouse. As shown in FIG. 18, the viewpoint change request point SV is anchor information (for example, external information providing image information of another viewpoint) for acquiring an image obtained by changing the viewpoint from an image obtained by photographing the designated section SS4 from the point. Embedded hyperlink information (such as server url). If there is no designation change request, the structure is arranged and displayed on the overhead view as it is, and the process ends. If there is a designation change request, in step S53, the acquisition unit 311 acquires image information of another viewpoint. Here, as an image of another viewpoint, an image obtained by photographing a surrounding building from a road is suitable, and such an image can be easily obtained from a major search site via the Internet. Finally, in step S54, the CAD information generation unit 313 arranges and displays the structure on an image (image including an overhead view or an image including the vicinity of the designated section from the ground) based on image information of another viewpoint. When the arranged structure is deviated from the designated section, the user makes a position change request for correcting the position of the structure with the mouse, and the operation receiving unit receives the operation input of the request, and the CAD information generating unit However, it is preferable to change the position of the structure based on the request and arrange it in the image.

  FIG. 18 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV4 is converted into an image (street view image) OV4m1 in which the designated section SS4 is viewed from the point SV on the road by the processing by the CIGS 300. The acquisition unit of this system also acquires related information of the point SV. The point SV related information includes one piece of camera information such as the coordinates of the point SV, the shooting direction (including the tilt angle of the camera), the camera height (altitude), and the angle of view of the camera (up and down and left and right angles of view). It is desirable to include a part. The more information included in the point SV related information, the more accurate processing is possible. For example, as shown in the image OV4m1, if the left and right angle of view av is known, the angle aa1 from the left end to the point B and the angle aa2 from the point B to the point C can be obtained by a known geometric calculation. Is possible. This geometric calculation is performed by a CAD information generation unit. Positioning can be performed in the image of the designated section SS4 based on the angles aa1 and aa2 obtained in this way, and if the center of gravity GC of the structure SO4-c is obtained by a known geometric operation, the structure It is possible to arrange SO4-c at an appropriate position in the image. There are many known positioning methods in the image, and the present invention is not limited to the above-described method. In this example, the left and right angle of view has been described. However, if the vertical angle of view is known, the calculation can be properly arranged in the vertical direction by a known geometric calculation although the calculation is slightly complicated. It is. Further, even when image information in all directions of 360 degrees can be obtained as a panoramic image, it is possible to obtain a pseudo view angle with respect to the cut-out image “view” displayed on the display device by calculation. It is possible to arrange a structure appropriately by the method of. By such geometric calculation and the spot SV related information, the “structure SO4-c” displayed in three dimensions on the designated section SS4 is appropriately arranged in the image OV4m1. In this way, according to CIGS 300, a structure customized according to the attributes of the designated section is displayed only by an extremely simple operation of designating a desired section and inputting a viewpoint change request. It is possible to provide an “image of a designated section viewed from a road”.

  FIG. 19 is a flowchart illustrating a modification of the process illustrated in FIG. In this example, a process will be described in a case where an operation input for designating a reference object is further received after the display is changed by the process of step S54 in response to the viewpoint change request of FIG. In the description of FIG. 18, it has been shown that positioning of sections and structures can be properly performed based on camera information such as angle of view and shooting point information. However, there is an error or error in scale information, camera information, or shooting point information. In such a case, the size of the structure may not be within an appropriate error range. In this example, a method for performing correction based on an object having a known dimension in an image (this is referred to as a reference object) will be described. As shown in the figure, in step S55, the operation accepting unit 312 accepts an operation input for designating a “reference object (for example, a window frame in which dimensions are generally determined)” for changing the dimensions of the structure. The CAD information generation unit 313 corrects the display size of the structure based on the dimension information of the reference object (stored in the storage unit in advance or input by the user when inputting an operation for designating the reference object). And display.

  FIG. 20 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the image OV4m2 is converted into the image OV4m3 by the processing by the CIGS 300. In the image OV4m2, “structure SO4-c” displayed in three dimensions on the designated section SS4 is arranged. The user designates the windows wd1 and wd2 of the existing building as reference objects. The storage unit stores a standard window size of 200cm (180cm for an old house). If a window reference is specified, the standard window size of 200cm is read and based on this standard size. The display size of the structure SO4-c is corrected to obtain the corrected structure SO4-r on the image OV4m3. The window wd3 included in the structure is also converted into the corrected window wd3-r. In this way, according to CIGS 300, the “road” that displays the structure customized according to the attributes of the designated section and the dimensions of the reference object can be displayed only by an extremely simple operation of designating the desired section and the reference object. It is possible to provide an “image for viewing the designated section”. The lines LN1 and LN2 of the other sections and the existing buildings and the line L3 of the designated section tend to have a certain inclination depending on the position of the viewpoint change request point SV. This system extracts a line having such a constant inclination by a known image processing method, and performs a correction process to process the line LN4 of the structure SO4-c so as to have the same inclination as the inclination. Also good. Of course, the user designates the line LN1-3 having a certain inclination as a reference line with a mouse or the like, and designates the line LN4 of a structure that should have the same inclination as the reference line with the mouse as a corresponding line, thereby performing correction processing. It is also possible to perform.

  FIG. 21 is a flowchart illustrating an example of processing executed in the system illustrated in FIG. Processing different from the processing described in the first embodiment will be mainly described. That is, the description of the process in step S61 is omitted. As shown in the figure, in step S62, the operation accepting unit designates a part suitable for installation or construction of a new structure (such as a building) as a designated section in the area shown in the overhead view. An input and a second operation input for designating a known reference object are received. In step S63, the storage unit generates CAD information of a different structure for each section attribute, or master CAD information including a plurality of CAD information corresponding to the section attributes, that is, patterns (shapes and site areas). Stores MCI. Furthermore, it is preferable to store the dimension information of the reference object. In step S64, the CAD information generation unit refers to the master CAD information MCI, and draws a structure that is allowed to be installed or constructed in the designated section based on the section attributes and reference objects. (For example, a three-dimensional model) is generated. Finally, in step S65, the CAD information generation unit arranges the structure drawn based on the CAD information on the designated section of the overhead view and displays the structure on the display unit.

  FIG. 22 is an explanatory diagram for explaining an image obtained by the processing shown in FIG. As shown in the figure, the overhead view OV5 is converted into the overhead view OV5m by the processing by the CIGS 300 (this example can also be implemented in the CIGS 100, 200). In the overhead view OV5, the user designates the points A, B, C, and D that define the designated section SS5 as candidate sites as the first operation input, and uses the pool PL as the reference object near this section for the second operation. Specify as input. The pool PL may specify its four vertices, or specify only one arbitrary point where the pool PL is located, and determine (estimate) the rectangular area of the pool PL by known image processing. . Many outdoor pools taken with satellite and aerial photographs have basic dimensions (for example, 25 m long and 10 m wide). The dimensions of such reference objects are stored in advance in the storage unit. If a pool is specified, use the dimensions of the pool, and for other standards, use the appropriate dimensions. If the size of the pool PL is used as a reference object, the size and site area of the designated section SS5 can be calculated without acquiring scale information or registration information. Based on the site area of the designated section calculated in this way and the pseudo survey results obtained by calculating the vertical and horizontal sites, the structure SO5 suitable for the site is arranged and displayed on the overhead view OV5m. Even when the scale information can be acquired, there is an error in the information. Therefore, it is preferable to perform an appropriate correction based on the dimension information of the reference object as in the present method. Although the pool and the window frame are illustrated as the reference objects, other reference objects whose dimensions can be predicted in advance may be used.

  Although common to all the embodiments, the contents of the master CAD information MCI will be described. Preferably, the master CAD information includes a unit (a room unit including a wall, a floor, a toilet, a bath, a window, an entrance, a ceiling, a roof, a wall, a floor, a ceiling, etc.) or a unit configuration. Information (structure design information) of components (flooring, wall boards, ceiling materials, windows, doors, sashes, etc.) that can be used in or as a component of the structure alone, A construction rule for creating a structure by connecting them is stored, and the present system refers to the master CAD information and generates CAD information of “new structure” based on the attribute of the section. Before generating CAD information based on the attribute of a section, it is preferable to obtain a building space in the section as a preliminary work. For example, if the building restriction information such as the building coverage ratio, the floor area ratio, the front road, the adjacent land, and the sky ratio of the designated section can be acquired or estimated, it is possible to obtain a building space.

  By designating the area of the existing building KO1 and the area of the existing building section KR1 with the mouse, acquiring the operation input, and dividing the area of the existing building KO1 by the area of the existing building section KR1, It is also possible to calculate the estimated occupancy rate. By increasing the number of samples, such as existing buildings KO2, KO3, existing building sections KR2, KR3, and calculating the average value, a more accurate estimated occupancy ratio is obtained, and the estimated occupancy ratio is used as the building restriction information for the designated section. May be. This method can be applied when 3D CAD information of an existing building as shown in FIG. 12 can be obtained. In this case, the area designation of the existing building section and the existing building installed in the area are designated. By specifying a three-dimensional structure, it is possible to obtain the estimated volume ratio. Specifically, if a standard floor height (for example, 3 m) is used, it is possible to calculate the total floor area of the three-dimensional structure of the existing building, and divide this by the area of the existing building section. Thus, it is possible to calculate the estimated volume ratio. It is preferable to use such estimated information when public building restriction information such as a building coverage ratio and a floor area ratio cannot be acquired. Furthermore, similarly, it is preferable to calculate estimated values of information such as oblique line restriction lines, height restrictions, and shadow restrictions from the shape of existing buildings, and use these as construction restriction information.

  FIG. 23 is an explanatory diagram of a method for generating CAD information. As shown in the drawing, the building space PV of the structure is obtained based on the attributes of the designated section SS6 (for example, building restriction information such as a building coverage ratio, height restriction, oblique line restriction). The buildable space PV is located on the building area PA. Although it depends on the building restriction information, the buildable space PV and the building area PA may move, increase / decrease, or deform on the designated section. After that, when the floor area ratio and the floor height are taken into consideration, it becomes possible to obtain an outer frame (such as three-dimensional CAD information constituting the appearance) of the new structure SO6 in the building space PV. As an element constituting such a structure SO6, final CAD information is generated by connecting several units constituting the structure and embedding them in the structure SO6. In this figure, CAD information for a two-story structure SO6 composed of the first floor (1F) and the second floor (2F) is generated. The structure SO6 is a two-story structure, but when there is a margin in the height restriction, the space is expanded upward like the building-capable space PV-a. Since the structure fits in the possible space PV-a, the three-story structure SO6-a including the third floor (3F) may be generated within the limit of the volume ratio.

  In addition, as the building restriction information of the designated section, for example, information on the north side adjacent land NN, direction information, and information on the north side oblique line restriction line (position where the restriction line should be placed, the angle of the restriction line, etc.) A space such as a building space PV-b obtained by cutting the building space PV-a along the north oblique line NTL is a building space. Therefore, in this space, the structure within the range allowed by the volume ratio has a structure in which the north side of the second and third floors such as the structure SO6-b is gradually cut off. The structure deformation (generation) method in consideration of such a building-possible space is the same in other adjacent places, and the same applies when considering the sky rate and the shadow regulation.

  Master CAD information can also include construction rules. For example, up to 50 square meters of land is a three-story house, the first floor is the entrance, the western room, the second floor is the living room, the toilet, the bathroom, the third floor is the bedroom. The construction rule of 50m2 or more is set up on the 2nd floor 1st floor with entrance, western room, living room, toilet, bathroom, 2 children's room on the 2nd floor, and can be accommodated in the building space. Yes, the CAD information may be generated by selecting an appropriate unit that satisfies the building restriction information such as the building coverage ratio, the floor area ratio, the shade restriction, and the oblique line restriction.

  Alternatively, in the master CAD information MCI, for example, existing CAD design information designed and accumulated by a company or an organization in the past can be stored and used. Furthermore, the CAD information of each structure newly designed according to the size and shape of several sites may be stored in the master CAD information MCI. Also, CAD information of office buildings for commercial districts and general houses for residential districts is prepared and stored in master CAD information MCI. The master CAD information preferably includes site information (that is, information on the site where the structure is built and the installation location of the structure, and orientation information on the site and the structure). The CAD information generation unit matches the designated section information with the information included in the master CAD information MCI, selects the CAD information of the structure having the site information having the highest similarity, and selects the selected CAD information. By appropriately correcting the structure, the CAD information of the structure customized to the section is obtained. For example, if the designated area is smaller than the site area of the matched site information, the structure itself should be reduced accordingly, and the internal room can be deleted, or the size of the living room etc. can be reduced. It is suitable to cope with.

<Embodiment 4>
FIG. 24 is a block diagram showing an outline of a CAD information generation system (CIGS) according to an embodiment of the present invention. As illustrated, the CIGS 400 includes a control unit (CPU) 410, an input unit 420, an output unit 430, a communication unit 440, a storage unit 450, and a display unit 460. The control unit 410 includes an acquisition unit 411, an operation reception unit 412, and a CAD information generation unit 413. The control unit 410 further includes an estimation processing unit 414 and an environmental equipment contribution numerical value calculation unit 415. The storage unit 450 stores master CAD information MCI including at least one CAD information corresponding to the attribute of the section, and at least one building restriction information CLI, and further, coordinates (for example, latitude and longitude) and an address (for example, xx). Address information AI associated with city yy town z chome y address, etc.) is stored. In addition, the acquisition unit 411 controls the communication unit 440 to register the registration information providing server RIDS or the public information providing server PIDS via the network NET based on the address (not the complete address but any level). Registration information and public information (for example, public maps that are public maps, textures, land use, oblique line regulation, building height restrictions, building coverage ratio, floor area ratio, etc.) The CAD information may be generated using the target information as the building restriction information. In particular, when a public map is obtained, it is possible to generate CAD information for generating a structure that accurately applies oblique line regulation, for example, north side oblique line regulation, because the adjacent land and road attachment are known in detail. It becomes.

  The master CAD information MCI in this embodiment further includes CAD information of environmental equipment that uses natural energy such as solar battery panels, solar water heater units, wind power generators, rainwater use tanks, and other natural resources such as rainwater. Therefore, the CAD information generation unit 413 can generate CAD information of a structure in which an environmental device such as a solar battery panel is installed and mounted on a roof, a rooftop, a wall surface, a site of a designated section, or the like. In addition, the storage unit 450 stores estimate information EI, process information PI, environmental equipment numerical information NEI, and position-specific environmental equipment numerical information LNEI. Estimated information EI is a unit that constitutes the structure targeted by CAD information (wall, floor, toilet, bath, window, entrance, ceiling, roof, room unit including wall, floor, ceiling, etc., concrete foundation on which the building is placed. Etc.), or members (flooring materials, concrete, stone, reinforcing bars, wall boards, ceiling materials, windows, doors, sashes, etc.) that can be used to construct a unit or to be used as a structural component alone Unit price information (such as building fixtures, wiring fixtures, wiring, etc.), unit price information for standard processes when using units or components (such as unit price for wallpaper construction work), and necessary for installing and constructing structures in designated sections Unit price information for standard processes (for example, effective unit price per square meter of foundation work), unit price information for each house (unit price), and unit price information for each unit (unit price for civil engineering such as leveling) ) Including. The process information PI includes a standard process required for installing and constructing one structure. Standard processes include, for example, standard house processes including basic construction, carpentry, and electrical work for two-story wooden houses, work processes related to parts and units (for example, loading of bus units, connection of upper and lower sewage pipes) Including construction work that includes a work site that is not directly related to components or units such as site preparation.

In addition, when the estimated information EI includes the environmental equipment unit price information and the purchased power unit price information of the acquired power, the environmental equipment contribution numerical calculation unit 415 returns the investment effect of the environmental equipment (the investment amount of the environmental equipment over the years). It is possible to calculate income and expenditure information for grasping, for example, how many years of profits can be obtained by purchasing electricity.

  Environmental equipment numerical information LNEI by position is weather information such as annual sunshine hours information for environmental equipment using solar heat and sunlight, climate information, or wind power for wind power generators by region, address, latitude and longitude. Information, including annual rainfall information for rainwater tanks. The environmental equipment contribution numerical value calculation unit 415 calculates the more accurate amount of electric power that can be acquired by natural energy, using the sunshine duration information and weather information for each position. As the simplest method, it is possible to use a method of multiplying the standard value of the environmental equipment in Japan by a correction coefficient considering weather information and the like. Alternatively, taking these weather information and environmental equipment installation status into consideration, prepare the numerical values for each environmental device in advance for each location, and use the environmental device values corrected for each location to determine the weather for each location. Environmental device contribution numerical values such as predicted power consumption considering information and weather information may be directly calculated.

Next, in step S72, the operation reception unit 412 has a portion (for example, a vacant lot, a parking lot, and a simple building) suitable for installation or construction of a new structure (building, etc.) in the area shown in the overhead view. An operation input that designates a designated area as a designated section is received. In step S73, the storage unit 450 generates CAD information of a structure that differs for each section attribute (for example, three-dimensional model information that generates three-dimensional modeling corresponding to the section). Master that includes multiple CAD information corresponding to the shape and site area, CAD information of environmental equipment that uses natural resources such as natural energy and rainwater, such as solar battery panels, solar water heater units, wind power generators, rainwater use tanks, etc. CAD information MCI is stored. In step S74, the CAD information generating unit 113 refers to the master CAD information MCI, and based on the designated section, CAD information for drawing a structure that is allowed to be installed or constructed in the designated section (for example, 3D model), but the master CAD information MCI includes the CAD information of the environmental equipment. For example, when the area sufficient to install the solar battery panel on the roof of the structure is obtained, the environmental equipment CAD information for drawing a structure including a solar battery panel on the roof is generated. Finally, in step S75, the CAD information generation unit 413 arranges the structure including the environmental device drawn based on the CAD information on the designated section of the overhead view and causes the display unit 460 to display the structure.

  FIG. 26 is a flowchart illustrating an example of an estimation process executed in the system illustrated in FIG.

Generate required process information for installation. In step E12, the estimate processing unit 414 generates approximate estimate information of the structure to be constructed based on the CAD information with reference to the estimate information EI based on the generated required process information.

  FIG. 27 is a flowchart illustrating an example of the calculation process for the environmental equipment contribution value executed in the system illustrated in FIG. As shown in the figure, in step P11, the environmental contribution numerical value calculation unit 415 refers to the environmental device numerical information based on the environmental device included in the CAD information, and the expected numerical value (power generation amount, etc.) that can be obtained by the environmental device. Calculate In step P12, the environmental contribution numerical value calculation unit 415 refers to the environmental device numerical information by position and corrects the predicted numerical value. In Step P13, the environmental contribution numerical value calculation unit 415 calculates the CO2 reduction amount and the balance due to the installation of environmental equipment based on the corrected predicted numerical value.

  FIG. 28 is a flowchart illustrating an example of a calculation process for the environmental equipment contribution numerical value considering the topography of adjacent sections and the influence of existing buildings. The processing of steps P11, P12, and P13 is the same as each step in FIG. In Step P12-1, the environmental contribution numerical value calculation unit 415 further corrects the predicted numerical value based on the degree of influence on the environmental equipment by the topography of the adjacent sections, existing buildings, existing structures, and the like. For example, if there is information on the position, height, direction, etc. of public structures such as existing buildings and utility poles in adjacent sections, the effect of sunlight on environmental equipment contained in the new structure can be used as a correction factor called impact. Can be defined. By using this correction coefficient as the degree of influence and multiplying the predicted numerical value, it is possible to calculate a more appropriate environmental equipment contribution numerical value (electric power amount, CO2 reduction amount, etc.) in consideration of the surrounding environment.
