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

As an example, when the target information input screen shown in FIG. and at least one landscape element of a building) in the input area 15A, and after inputting the landscape element of interest in the input area 15B, the end button 15E is specified. Accordingly, step 206 makes an affirmative determination, and the process proceeds to step 208 . Hereinafter, the landscape element to be divided input by the user will be referred to as the "applied landscape element", and the landscape element of interest will be referred to as the "viewed landscape element".

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

FIG. 8 shows an example of an image before and after segmentation by image segmentation technique. The left diagram in FIG. 8 is an example of an image before division (referred to as "original image" in FIG. 8), and the right diagram in FIG. 8 is an image after division of the image ("segmentation image" in FIG. 8). notation.) is an example. In the example shown in FIG. 8, vegetation, a sidewalk, a roadway, a building, and the sky are applied as applicable landscape elements, and each landscape element is represented with a different concentration.

At step 210, the derivation unit 11C extracts the landscape information indicating the ratio of the area between the divided regions for each applicable landscape element obtained by the above processing (hereinafter referred to as "area ratio") to all of the read image information. is derived for each image information. In this 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 as landscape information for each image information. be done.

FIG. 9 shows a plurality of landscape elements (eg, vegetation) arranged in the width direction shown in FIG. 4), landscape information at the position of the vertical plane is shown with different densities for each area ratio. In this example, for example, in each of the vertical planes shown in FIG. 9, if the number of shooting locations in the corresponding vertical plane is 100 in the depth direction and in the height direction, then 100 locations×100 locations=10000 Landscape information at the point is shown. In addition, in the example shown in FIG. 9, the higher the area ratio, the higher the density.

At step 212, the execution unit 11D uses the landscape information for each image information obtained by the above processing to generate an image showing the landscape information (area ratio) regarding the landscape element of interest specified by the user. Mapping processing is performed to virtually map to the corresponding position of the outer wall surface of the target building.

At step 214, the execution unit 11D controls the display unit 15 to display a screen displaying the target building subjected to the mapping process (hereinafter referred to as "mapping screen").

FIG. 10 shows an example of a mapping screen according to this embodiment.

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 on the outer wall surface of the target building 50 . Therefore, in order to satisfy the landscape conditions required for the target building 50 or to emphasize the appealing points imposed on the target building 50, the user may change the external shape of the target building 50, change the shape of the target building 50, or change the shape of the target building 50. The layout of each room provided in the target building 50 can be changed, and the arrangement position of various facilities provided in the target building 50 can be changed. Hereinafter, these various changes to the target building 50 are referred to as "building changes".

As an example, when the mapping screen shown in FIG. 10 is displayed, if the user wishes to display each value of the landscape information of a desired position, the user designates the landscape information display button 15C via the input unit 14, and then , specify the position where you want to display the landscape information. If the user wishes to change the target building 50, the user designates the change building button 15D via the input unit 14, and then performs an operation for changing the desired building.

Therefore, in step 216, the executing section 11D determines whether or not the landscape information display button 15C is designated by the user, thereby determining whether or not the display of the landscape information is designated by the user. goes to step 218 . At step 218, the execution unit 11D waits until the user designates a position where the landscape information is to be displayed. At step 220, the execution unit 11D performs control to display the scenery information corresponding to the position specified 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 this embodiment, landscape information is displayed in the form of a so-called speech balloon for a designated position. By displaying this landscape information, the user can grasp more detailed landscape information, and can perform more detailed building design.

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 user has specified to change the building. If the determination is affirmative, the process proceeds to step 224 .

At step 224, the execution unit 11D waits until the user completes the operation for changing the building. At step 226 , the execution unit 11</b>D performs processing for reflecting the building change made by the user in the building object 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 placed at desired positions with desired sizes and shapes in the target building 50 by the user. It is shown.

At step 228, the execution unit 11D determines whether or not the end button 15E has been specified on the mapping screen, thereby determining whether or not the user has instructed to end the building design support process, resulting in a negative determination. If so, the process returns to step 216, and if the determination is affirmative, the building design support process is terminated.

By using the landscape information presented to the user by the above-described building design support processing, for example, an open exterior such as a glass wall can be provided at a position with a large area ratio of vegetation, while at a position with a small area ratio of vegetation , It is possible to consider the landscape quantitatively, such as providing non-residential rooms such as machine rooms and warehouses. In addition, if the target building is a rental property such as an apartment, office, restaurant, attraction facility, etc., quantifying the scenery from various parts of the building enables more appropriate rent setting. For example, in a condominium that claims an ocean view, it will be possible to quantify the area ratio of the sea when looking out of the window and set the rent according to that figure.
