As shown in FIG. 5, in the present embodiment, the position information is indicated by three-dimensional coordinates with a predetermined position (in the present embodiment, a predetermined origin position in the building target model 70) as the origin. The information is being applied. However, the position information is not limited to the above form, and it goes without saying that any information can be applied as long as it is information that specifies the shooting position by the flying object 80.

Next, the operation of the building design support device 10 according to the present embodiment will be described with reference to FIGS. 6 to 12. When an instruction input for starting execution of the building design support program 13A is performed by the user via the input unit 14, the CPU 11 of the building design support device 10 executes the building design support program 13A, whereby FIG. The building design support process shown is executed. In addition, here, in order to avoid confusion, the case where the building information database 13B and the photographed image information database 13C have already been constructed will be described.

In step 200 of FIG. 6, the acquisition unit 11A reads the building target model 70 to be processed from the building information database 13B, and in step 202, the acquisition unit 11A reads all the position information and images related to the read building target model 70. Information is read from the captured image information database 13C. In step 204, the acquisition unit 11A controls the display unit 15 so as to display the target information input screen having a predetermined configuration, and in step 206, the acquisition unit 11A waits until the predetermined information is input. To do.

FIG. 7 shows an example of the target information input screen according to the present embodiment. As shown in FIG. 7, on the target information input screen according to the present embodiment, the landscape element to be divided is input together with the message prompting the input of the landscape element to be divided and the landscape element to be focused on. The input area 15A and the input area 15B for inputting the landscape element of interest are displayed.

As an example, when the target information input screen shown in FIG. 7 is displayed on the display unit 15, the user can use the input unit 14 to divide the landscape elements (in the present embodiment, the sky, the sea, vegetation, and the road). And at least one landscape element of the building) is input to the input area 15A, the landscape element of interest is input to the input area 15B, and then the end button 15E is specified. In response to this, step 206 becomes an affirmative determination, and the process proceeds to step 208. In the following, the landscape element to be divided, which is input by the user, is referred to as an "applied landscape element", and the landscape element of interest is referred to as a "focused landscape element".

In step 208, the division unit 11B divides the image indicated by each image information into each element of the applied landscape element by using the above-mentioned image segmentation technique for all the read image information.

FIG. 8 shows an example of images before and after division for each element by the image segmentation technique. The left figure of FIG. 8 is an example of the image before division (indicated as “original image” in FIG. 8), and the right figure of FIG. 8 is the image after division with respect to the image (“segmentation image” in FIG. 8”. It is an example of.). Further, in the example shown in FIG. 8, vegetation, sidewalks, roadways, buildings and the sky are applied as applicable landscape elements, and each landscape element is represented by a different concentration.

In step 210, the derivation unit 11C reads out all the image information indicating the landscape information indicating the ratio of the area between the divided regions for each applied landscape element (hereinafter, referred to as “area ratio”) obtained by the above processing. Is derived for each image information. In the present embodiment, as described above, the ratio of the number of pixels of the corresponding image information in the area occupied by the corresponding landscape element is applied as the landscape information. As a result, for example, for certain image information, information (area ratio) such as "40 (sky): 10 (sea): 15 (vegetation): 20 (road) ..." is derived for each image information as landscape information. Will be done.

In FIG. 9, when the site 60 shown in FIG. 3 is treated, one landscape element (vegetation as an example) in the applicable landscape element is arranged in the width direction shown in FIG. 3 (example shown in FIG. 9). An example is shown in which the landscape information at the positions of the vertical planes (4 planes) is expressed in different concentrations for each area ratio. In this example, for example, in each vertical plane shown in FIG. 9, when there are 100 imaging locations in the corresponding vertical plane in the depth direction and the height direction, 100 locations × 100 locations of 10000 Landscape information at the location is shown. In the example shown in FIG. 9, the larger the area ratio, the higher the concentration.

In step 212, the execution unit 11D uses the landscape information for each image information obtained by the above processing to create an image showing the landscape information (area ratio) regarding the landscape element of interest specified by the user, in the building target model 70. Performs a mapping process that virtually maps to the corresponding position on the outer wall surface of the target building in.

In step 214, the execution unit 11D controls the display unit 15 so as to display a screen (hereinafter, referred to as “mapping screen”) for displaying the target building that has been mapped.

FIG. 10 shows an example of a mapping screen according to the present embodiment. As shown in FIG. 10, on the mapping screen according to the present embodiment, the landscape element of interest designated by the user (“sky” in the example shown in FIG. 10) is displayed, and the target building 50A that has been mapped is displayed. Is displayed. As shown in FIG. 10 as an example, in the mapping process according to the present embodiment, the landscape information (area ratio) at the position of the surface corresponding to the outer wall surface of the target building 50 is described with reference to FIG. 9 as an example. It is displayed at the position of the corresponding outer wall surface as an image showing the area ratio with different densities.

By referring to the mapping screen shown in FIG. 10 as an example, the user can intuitively grasp the area ratio occupied by the landscape element of interest at each position of the outer wall surface of the target building 50. Therefore, the user changes the external shape of the target building 50 and changes the target building 50 in order to satisfy the landscape conditions required for the target building 50 and to emphasize the appeal point imposed on the target building 50. It is possible to change the layout of each room provided in the target building 50, change the arrangement position of various facilities provided in the target building 50, and the like. In the following, various changes to the target building 50 will be referred to as "building changes".

When the mapping screen shown in FIG. 10 is displayed as an example, when the user wants to display each value of the landscape information at a desired position, after designating the landscape information display button 15C via the input unit 14. , Specify the position where you want to display the landscape information. Further, when the user wants to change the building for the target building 50, the user performs a desired building change operation after designating the building change button 15D via the input unit 14.

Therefore, in step 216, the execution unit 11D determines whether or not the landscape information display button 15C is specified, thereby determining whether or not the display of the landscape information is specified by the user, and a positive determination is made. Goes to step 218. In step 218, the execution unit 11D waits until the user specifies the position where the landscape information is to be displayed. In step 220, the execution unit 11D controls to display the landscape information corresponding to the position designated by the user on the mapping screen for a predetermined time (for example, 5 seconds), and then proceeds to step 228.

FIG. 11 shows an example of a mapping screen in which landscape information is displayed at a position designated by the user. As shown in FIG. 11, in the present embodiment, the landscape information is displayed in the form of a so-called balloon with respect to the designated position. By displaying this landscape information, the user can grasp more detailed landscape information and can design a more detailed building.

On the other hand, if a negative determination is made in step 216, the process proceeds to step 222, and the execution unit 11D determines whether or not the building change button 15D has been specified, thereby determining whether or not the building change has been specified by the user. If the determination is made and the determination is affirmative, the process proceeds to step 224.

In step 224, the execution unit 11D waits until the operation for changing the building by the user is completed. In step 226, the execution unit 11D performs a process of reflecting the building change made by the user in the building target model 70, and then proceeds to step 228. If a negative determination is made in step 222, that is, if neither the landscape information display button 15C nor the building change button 15D is specified by the user, the process proceeds to step 228 without performing any processing. ..

FIG. 12 shows an example of a mapping screen when a plurality of facilities (two windows in the example shown in FIG. 12) are arranged at a desired position with a desired size and shape with respect to the target building 50 by the user. It is shown.

In step 228, the execution unit 11D determines whether or not the end button 15E is specified on the mapping screen, thereby determining whether or not the user has instructed the end of the building design support process, resulting in a negative determination. In that case, the process returns to step 216, and if a positive judgment is made, the building design support process is terminated.

By using the landscape information presented to the user by the above building design support process, for example, an open exterior such as a glass wall is provided at a position where the area ratio of vegetation is large, while an open exterior such as a glass wall is provided at a position where the area ratio of vegetation is small. It is possible to give consideration to the quantitative landscape, such as providing non-living rooms such as machine rooms and warehouses. In addition, when the target building is a rental property such as an apartment, office, restaurant, attraction facility, etc., it is possible to set a more appropriate rent by quantifying the scenery from each part of the building. For example, in a condominium that sings an ocean view, it is possible to quantify the area ratio of the sea when looking out from the window and set the rent according to that value.

As described above, according to the present embodiment, acquisition of image information obtained by photographing at least in the direction outside the building at a predetermined position in the site of the building at the planned construction site of the building.
