[Modes for carrying out the invention]

[0018] Hereinafter, typical embodiments of the land and building plan generation method, apparatus, and system according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to these drawings. Since the drawings are for conceptual explanation of the present invention, dimensions, ratios, or numbers may be exaggerated or simplified as necessary for ease of understanding.

[0019] 1. Overall configuration of the land and building plan generation system As shown in Figure 1, the land and building plan generation system 1 (hereinafter referred to as System 1) can be configured as a computer system including a user terminal 3 and a land and building plan generation device 5 (hereinafter referred to as Plan Generation Device 5) that is connected to the user terminal 3 via a communication network. In the illustrated example, the user terminal 3 and the Plan Generation Device 5 are configured as separate devices, but the user terminal 3 and the Plan Generation Device 5 may be configured as a single device.

[0020] The user terminal 3 and the plan generation device 5 may each be connected to an external database 7 in a communication manner. The external database 7 is, for example, a map database that stores map data, etc. Alternatively, the external database 7 may be a building database as described later.

[0021] In the system 1 according to this embodiment, the plan generation device 5 extracts buildings suitable for the desired land in response to a request from the user terminal 3 and outputs them to the user terminal 3. The user terminal 3 combines the received building data with predetermined land information to generate a land and building plan (hereinafter referred to as "plan"). The generated plan is made available to the user through methods such as screen display or printing. In the sense described above, the plan generation device 5 may also be called a building extraction device. The user terminal 3 and the plan generation device 5 will be described in detail below.

[0022] 2. About user terminals User terminal 3 is a computer used by the user. The user is typically a real estate service provider, but could be any other type of business or even a general consumer.

[0023] Although User Terminal 3 is shown as a single entity in Figure 1, it represents multiple terminals. User Terminal 3 can be any type of computer, such as a desktop, notebook, tablet, smartphone, or personal digital assistant (PDCA). The hardware configuration of User Terminal 3 will be described later.

[0024] The user terminal 3 can execute application programs such as a browser and communicate with the plan generation device 5 and the external database 7 via a communication network. For example, the user terminal 3 may be configured to perform the following processes (1)-(5).

[0025] (1) Create the desired land shape. User terminal 3 can create image data showing the desired land shape in response to user operations. Here, "land shape" refers to the planar shape of the land, but may also include information indicating the land's condition, such as slope and topography. The land can be a regularly shaped plot, such as a square or rectangle, or an irregularly shaped plot, such as a triangle or L-shape. In many cases, land shape can be represented by a polygon.

[0026] It is preferable for user terminal 3 to create the desired land shape on a map (see Figure 5). User terminal 3 can obtain map data from an external database 7 to display a map on its screen. External database 7 can include, but is not limited to, official map databases such as cadastral maps and maps kept at land registry offices, as well as various private map databases such as Google Maps and Zenrin Residential Maps. For example, user terminal 3 can access external database 7 via an application programming interface (API). Alternatively, user terminal 3 may use map data stored in its own storage device.

[0027] Furthermore, the user terminal 3 can acquire data indicating the location of the desired land in response to user operations (for example, inputting or selecting a location by the user, or selecting a location on a map). Here, the method of identifying the location can be anything, for example, it may be displayed as an address, or it may be expressed as latitude and longitude.

[0028] For example, user terminal 3 can accept a string input into the location input field on the displayed website and obtain the entered string as the location of the desired land (see Figure 4). Alternatively, user terminal 3 can obtain the location of a desired plot of land by having the user select or specify the desired plot on a map embedded in the website. To facilitate this process, user terminal 3 can display a region selection button on the website (see Figure 4) and display a map of the selected region according to the user's selection. Therefore, user terminal 3 can display an appropriate map covering the selected location and create a terrain model on that map.

[0029] User terminal 3 may create a terrain shape by drawing lines around the relevant areas on the map displayed on the screen. For example, user terminal 3 can create a terrain shape by detecting user operations (e.g., mouse clicks) to generate three or more points on the map and connecting these points with lines (especially straight lines). Alternatively, user terminal 3 may automatically generate the landform of the selected location using map data. For example, user terminal 3 may obtain the boundary line between the selected location and the adjacent land from the map data and set such boundary line as the landform of the selected location.

[0030] User terminal 3 may represent the points and lines representing the terrain in a different way (e.g., different colors, line types, or thicknesses) than the background map in order to improve the visibility of the terrain image. User terminal 3 may also color the inside of the created terrain.

[0031] (2) Specify the road frontage in the created land plan. User terminal 3 can specify or select the road frontage area in the created land shape (see Figure 7). Here, the road frontage area is the line in the image representing the land shape that faces the road, and can also be called the road surface. The road frontage area overlaps with the line representing the road on the map, or can be said to be the closest to the line representing the road.

[0032] To specify or select the road frontage, user terminal 3 can utilize the lines that make up the terrain (see Figure 8). For example, if the terrain is composed of multiple points and line segments connecting those points, the user terminal 3 can select one or more line segments constituting the terrain as road access points. Specifically, the user terminal 3 may detect when the relevant line segment is clicked by the mouse and designate that line segment as a road access point. Alternatively, the user terminal 3 may automatically set the road frontage portion of the land shape using the created land shape and map data (e.g., road data). For example, the user terminal 3 may set the road frontage portion as the part of the land shape that overlaps with or is closest to the road lines among the lines representing the land shape. User terminal 3 may display the selected road access area in a different way from other areas (for example, with a different color, thickness, or line type).

[0033] (3) Obtaining land information relating to the desired land. User terminal 3 can obtain land information relating to the desired land. Here, the land information includes, but is not limited to, the area of ​​the land (e.g., site area), and may also include, for example, the building coverage ratio, floor area ratio price, whether or not it is within an urban planning area, and the type of land use zone. The land information may also include information relating to the orientation of the land (e.g., south).

[0034] User terminal 3 may acquire the above land information in response to user input. For example, user terminal 3 may accept user input from an input field on a website displayed on its screen and register it as land information (see Figures 6 and 8). Alternatively, user terminal 3 may perform the calculation using acquired data (e.g., land shape, map data, land use zone of the land, etc.).

[0035] Additionally, user terminal 3 may acquire building conditions, including at least one of the following: number of floors, floor plan, price, area, and total floor area, in response to user input (see Figures 6 and 9). It should be noted that the land information and building conditions mentioned above are not strictly separate, and there may be items common to both. Furthermore, there are no particular restrictions on the order in which the land type is created, the land information is acquired, and the building conditions are acquired (see Figures 6 and 7).

[0036] (4) Requesting a land and building plan from the plan generation device 5 User terminal 3 can request a land and building plan from plan generation device 5. Here, the request for a land and building plan may also be a request for data (such as building data) that indicates the content of the plan. For example, user terminal 3 can send an HTTP request to plan generation device 5 that includes a request for a land and building plan. When requesting a plan, or afterward, the user terminal 3 can transmit the location of the land, the created land shape, the specified road frontage, the acquired land information, and (if applicable) the building conditions to the plan generation device 5.

[0037] (5) Presenting land and building plans to the user. User terminal 3 can present a land and building plan to the user. For example, user terminal 3 can receive data indicating the contents of the land and building plan (e.g., building data) from the plan generation device 5, generate a land and building plan using this data (for example, in combination with land information and building conditions, etc.), and provide the plan to the user. Examples of provision methods include screen display, printing, download, and email transmission. Alternatively, user terminal 3 can receive the land and building plan from the plan generation device 5 and provide it to the user.

[0038] 3. About the plan generation device The plan generation device 5 will be described in detail with reference to Figure 2. The plan generation device 5 is a computer used by a service provider that provides services to users. The plan generation device 5 may consist of one unit or multiple units.

[0039] The plan generation device 5 can be configured as a server device (see Figure 1), but is not limited to this. The plan generation device 5 as a server device can be of any type, such as a cloud server, virtual private server (VPS), dedicated server, web server, or application server. Alternatively, the plan generation device 5 may be configured as a device or computer integrated with the user terminal 3.

[0040] The plan generation device 5, acting as a server device, may be configured to receive a request from the user terminal 3 and execute the following processes (a)-(c).

[0041] (a) Obtain various data from user terminal 3. The plan generation device 5 can receive various data from the user terminal 3, such as the location of the land, the shape of the land, the road frontage, other land information, and building conditions. The component that performs the above function in the plan generation device 5 can be called the acquisition unit 51. For example, when the plan generation device 5 receives access from the user terminal 3, it can display a predetermined website on the user terminal 3. This website includes input fields for location, map display, and land information (see Figures 4-9).

[0042] Furthermore, this website allows the creation of a plot shape and the designation of road frontages on the displayed map (see, for example, Figures 6-8). Here, the plot shape can be created using known drawing methods. For example, in the plot shape creation mode, the plan generation device 5 can draw three or more points on the map in response to mouse clicks by the user, and when a click is detected on the first point drawn, it can connect those points with lines in the order they were generated. Also, in the road frontage designation mode, the plan generation device 5 can select a line segment as a road frontage when a click is detected on any of the line segments that make up the plot shape. In addition, the plan generation device 5 can designate a parking area within the plot shape using the same method as for plot shape creation (see Figure 8). The plan generation device 5 can obtain the data necessary for the plan via such a website.

[0043] (b) Extract at least one building from the building database that meets the criteria. The plan generation device 5 can extract at least one building from the building database 52 that matches predetermined extraction conditions. The component that performs the above function in the plan generation device 5 can be called the building extraction unit 53.

[0044] Here, the building database 52 registers buildings in association with at least their area (e.g., building area and total floor area) and floor plans. The building database 52 may further include at least one of the following: the number of floors, the number of rooms, the price, the floor plan in the narrow sense (e.g., 1LDK, 2LDK, 3LDK), the exterior view, the interior view, the location and orientation of the entrance door in the floor plan, and the location and orientation of the main living room (e.g., living room). The exterior view may include multiple designs with different tastes.

[0045] Furthermore, there are no particular restrictions on the types of buildings that can be registered in the building database 52. For example, only buildings designed or constructed by a specific construction company or design office may be registered, or building data may be collected without such restrictions. In this embodiment, the building database 52 is included in the plan generation device 5, but it may also be provided outside the plan generation device 5, i.e., as an external database 7.

[0046] The extraction criteria include land shape, road frontage, and land information (e.g., land area, building coverage ratio, and floor area ratio). By considering these conditions, it is possible to extract buildings that are suitable (buildable) for the desired land. The extraction criteria may also include any of the building conditions mentioned above. By including building conditions in the extraction criteria, it becomes possible to extract buildings that are suitable not only for the land but also for the customer's preferences.

[0047] One example of a building extraction method is as follows. It goes without saying that building extraction methods are not limited to this.

[0048] In other words, the plan generation device 5 can extract buildings from the building database 52 whose building area is less than or equal to the land area. Preferably, the plan generation device 5 further narrows the selection to buildings that satisfy a given building coverage ratio. Alternatively, it is preferable that the plan generation device 5 narrows the selection to buildings that satisfy a given floor area ratio.

[0049] Furthermore, the plan generation device 5 can compare the building's floor plan with the shape of the land and determine whether the building will fit on the land. This process is preferably performed on buildings extracted through the above procedure. Even if a building is numerically suitable for the land, it may be impossible to construct it on the land depending on the shape of the land and the building itself, so such buildings are excluded from consideration.

[0050] For example, the plan generation device 5 displays the floor plan of the building to be compared and the shape of the land at the same scale, and overlays the building floor plan onto the shape of the land. In the example in Figure 12(A), the building (floor plan) Y is overlaid on the land (shape) X. In this case, the plan generation device 5 may translate, rotate, or flip the building floor plan vertically or horizontally relative to the shape of the land (see Figures (B)-(G)).

[0051] In this case, the plan generation device 5 may refer to the floor plan of building Y and find a suitable position and orientation of building Y on land X such that the entrance of building Y faces the road frontage of land X (land type), and store such position and orientation. The plan generation device 5 may further preferentially extract building Y such that the main living room faces a desired direction (for example, south), but this point will be described in detail in relation to Modification 1.

[0052] In addition, the plan generation device 5 may take parking space into consideration and evaluate whether the combination of the building's floor plan and the parking space fits within the shape of the land.

[0053] Based on the comparisons described above, the plan generation device 5 retains buildings that fit within the shape of the land. This extracts buildings that can be constructed on the desired land, and the extraction results are stored in the plan generation device 5.

[0054] (c) Output the extracted buildings. The plan generation device 5 can output (e.g., send or download) data related to the extracted buildings to the user terminal 3. The output data includes the area of ​​the building (e.g., building area and total floor area) and floor plan. The output data may further include the number of floors, number of rooms, price, floor plan in the narrow sense (1LDK, 2LDK, 3LDK, etc.), exterior view, and interior view of the building. The plan generation device 5 may also output the preferred location and orientation of the building on the desired land. If multiple buildings are extracted, related data is output for each building. The component that performs the above functions in the plan generation device 5 can be called the output unit 55. The outputted building data is combined with other data (e.g., land shape, road access, other land information, building conditions, etc.) in a predetermined format on the user terminal 3 to generate a land and building plan. When the user terminal 3 receives data for multiple buildings, it can generate multiple plans. The plan may be a simplified plan including at least one of the extracted building exterior view, interior view, estimated price, and site plan and floor plan on the land (see Figure 10), or it may be a detailed plan including a financial plan (e.g., land price, loan repayment plan, etc.) (see Figure 11).

[0055] Alternatively, the plan generation device 5 may generate at least one plan (land and building plan) that includes a combination of the desired land shape and the floor plans of the extracted buildings. The component that performs the above function in the plan generation device 5 can be called the plan generation unit 54. The plan generation device 5 can generate multiple plans when multiple buildings are extracted.

[0056] 4. Computers that can function as user terminals and plan generation devices A computer capable of functioning as a user terminal 3 and a plan generation device 5 will be described.

[0057] A computer includes an arithmetic unit, a memory device, and a communication interface (I / F), and may further include input and output devices. A computer may consist of one computer or multiple computers.

[0058] The arithmetic unit is a circuit that realizes various functions as a user terminal 3 and a plan generation device 5 by reading various programs and data into a storage device and executing them. The arithmetic unit may consist of a central processing unit (CPU), a graphics processing unit (GPU), and semiconductor integrated circuits such as a microprocessor.

[0059] The storage device includes random-access memory (RAM) and read-only memory (ROM) for storing the various data and programs described above. The storage device may also include, for example, a hard disk drive, a solid-state drive, and flash memory.

[0060] Input devices are used to input various types of data, such as keyboards, mice, touch panels, and microphones. Output devices are used to output various types of data, such as displays, printers, and speakers. User terminal 3 is equipped with input and output devices, but the plan generation device does not need to be equipped with these devices.

[0061] Communication interfaces are interfaces for connecting to wired and wireless communication networks, such as adapters for connecting to Ethernet®, modems for connecting to public telephone networks, wireless communication devices for wireless communication, USB (Universal Serial Bus) connectors for serial communication, and RS232C connectors.

[0062] 5. Operation of the Land and Building Plan Generation System Refer to Figure 3 to explain the overall processing flow of System 1.

[0063] User terminal 3 launches an internet browser in response to user input, accesses plan generation device 5, and displays a predetermined website on its screen. The displayed website includes a location input field and a region selection screen. In the example shown in Figure 4, the region selection screen is configured as buttons for selecting a region (prefecture) arranged to resemble a map of Japan, but it is not limited to this configuration.

[0064] User terminal 3 acquires location information for a desired plot of land based on the user's input of a location or selection of a region (step S1 in Figure 3), and displays a map containing that location on its screen (see Figure 5). For example, user terminal 3 can acquire map data from an external database 7 via an API and embed and display a map of a desired scale on a website.

[0065] User terminal 3 acquires the land shape of the above-mentioned land (step S2 in Figure 3). For example, user terminal 3 can switch to a mode for creating a landform (land information input mode) in response to user operations (for example, clicking the "Create Landform" button in Figure 5). In this mode, as shown in Figure 6, the progress of land information input is displayed at the top of the screen (or window), and a label indicating the current stage (in Figure 6, "1. Enclose the perimeter") is highlighted with color or other means, making it easy for the user to understand the progress.

[0066] The user terminal 3 can plot points on the map displayed on the screen in response to user operations (for example, detection of mouse clicks), connect these points with lines, and acquire the shape enclosed by these lines as the land shape. User terminal 3 can overlay the acquired landform onto the corresponding land on the map. In the example in Figure 7, the landform is colored, but the lines indicating the landform may be represented in a different way from the surrounding area (e.g., color, line type, thickness, etc.).

[0067] Next, user terminal 3 acquires the road frontage portion of the land in question. For example, user terminal 3 can acquire a portion (e.g., at least one line segment) of the lines representing the terrain, selected by user operation (e.g., mouse click), as the road-adjacent portion. User terminal 3 may display the acquired road frontage in a different way from the rest of the terrain (e.g., different line type, color, thickness, etc.). In the example in Figure 7, the road frontage is represented by a dashed line.

[0068] In addition, user terminal 3 acquires other land information related to the land in question (step S3 in Figure 3). For example, user terminal 3 can acquire land information in response to user input into designated input fields. In the example shown in Figure 7, the land area, building coverage ratio, floor area ratio, and location are entered, but as land information, it is sufficient to acquire at least the land area, and other data can be arbitrary.

[0069] Additionally, user terminal 3 can allow the user to input detailed land information. For example, user terminal 3 can open a separate window for detailed input of land information, depending on the user's selection. In the example shown in Figure 8, it is possible to specify not only the shape of the land and the road frontage, but also the location of the parking lot, and furthermore, urban planning, fire prevention zones, land use zones, etc. can be set.

[0070] Additionally, user terminal 3 can allow the user to input detailed building conditions. For example, user terminal 3 can open a separate window for detailed input of building conditions, depending on the user's selection. In the example in Figure 9, the number of floors, floor plan, price, building area, total floor area, and other conditions (e.g., conditions related to the kitchen) can be entered or selected.

[0071] User terminal 3 transmits the extracted building information suitable for the selected land to the plan generation device 5. In addition, user terminal 3 transmits the land shape, road access, other land information, and building conditions to the plan generation device 5.

[0072] The plan generation device 5 receives a request from the user terminal 3 and begins extracting buildings that are suitable for the desired plot of land.

[0073] In other words, the plan generation device 5 uses various data received from the user terminal 3 as extraction conditions to extract at least one building from the building database 52 (step S4 in Figure 3). For example, the plan generation device 5 extracts buildings smaller than the desired land area from the building database 52. Then, for each extracted building, the plan generation device 5 evaluates whether the building can be constructed on the land. This evaluation may be determined, for example, by superimposing the building's floor plan onto the land shape and determining whether the building's floor plan fits within the land shape (see Figure 12). In this case, the plan generation device 5 may prioritize extracting buildings whose entrance (doorway) can face the road frontage of the land, and store the layout of those buildings on the land. Further details will be described in Modification Example 1.

[0074] In addition, the plan generation device 5 may preferentially extract buildings in which the main living spaces can face south on the desired plot of land, and store the layout of those buildings on the land. Further details will be described in Modification Example 1.

[0075] Alternatively, the plan generation device 5 may prioritize extracting buildings that allow for parking space between the road frontage of the land and the building. Furthermore, by considering the land's building coverage ratio, floor area ratio, and building conditions, it is possible to extract buildings that have a more realistic feasibility of construction on the land in question.

[0076] The plan generation device 5 outputs the extracted building data to the user terminal 3 (step S4 in Figure 3). The output data may include information relating to multiple buildings.

[0077] User terminal 3 receives building data from plan generation device 5 and generates a land and building plan (step S5 in Figure 3). User terminal 3 can generate the above plan for each of multiple buildings. User terminal 3 can display the generated plan on the screen, print it, or download it (step S6 in Figure 3).

[0078] The plan preferably includes at least the shape of the land and a floor plan of the building superimposed on it, as well as a floor plan of the building (see Figure 10). The plan may further include an exterior view and an interior view of the extracted building. In addition, the plan may include the number of floors and rooms of the extracted building, the building area and total floor area, and an estimate of the construction cost (see Figure 11).

[0079] Therefore, the user can present or provide the plan output by user terminal 3 to the customer, or use the plan themselves. The plan displays a building that is suitable for the desired land, i.e., a building that can be constructed, along with its floor plan, exterior, etc. This allows the user to give the customer a concrete image of the land and building plan.

[0080] Furthermore, by extracting buildings whose entrance (front door) faces the road frontage of the property, it becomes easier for users and their customers to visualize the properties realistically.

[0081] Furthermore, including multiple plans in a single proposal increases the options available to users and their customers, which can lead to greater customer satisfaction.

[0082] Furthermore, by limiting the plan generation device 5 to extracting buildings and having the user terminal 3 generate the plan, the load on the plan generation device 5 can be distributed, and the plan generation process can be sped up.

[0083] Furthermore, when the user terminal 3 obtains additional or modified extraction conditions in response to user input or selection, it transmits those conditions to the plan generation device 5. When the plan generation device 5 receives additional or modified extraction conditions from the user terminal 3, it updates the extraction conditions and searches the building database 52 again using the updated conditions. The plan generation device 5 then re-extracts at least one building that satisfies the updated extraction conditions and sends the data of the re-extracted building to the user terminal 3. The user terminal 3 regenerates a plan using the re-extracted building and provides it to the user. This procedure is repeatable. Therefore, users can quickly revise plans as many times as needed until the customer is satisfied, leading to further improvements in customer satisfaction.

[0084] 6. Modifications of this embodiment Several modifications of this embodiment will be described.

[0085] Modification 1 relates to a method for extracting buildings from a building database. In other words, priority may be given to buildings that can be positioned on the plot of land such that the entrance of the building faces the road-facing portion of the plot. Here, "the entrance facing the road-facing portion" means that the road-facing portion is at least partially included within a predetermined angle 2α with respect to a direction approximately perpendicular to the entrance door. The predetermined angle 2α may be, for example, 0° to 60°, preferably 0° to 30°. In the example in Figure 13, a building with an entrance facing north is positioned on a plot of land where the road-facing portion is located on the north side. In this case, the building database stores the location and orientation of the entrance for each building.

[0086] In addition, priority may be given to buildings that can be positioned on a plot of land such that the main living room (e.g., living room) faces south on the desired plot. Here, the main living room facing south means that the south direction on the land is included within a predetermined angle 2β range with respect to the direction from approximately the center of the room toward the main opening (e.g., a window) (see Figure 13). The predetermined angle 2β may be, for example, 0° to 150°, preferably 0° to 120°. In the example in Figure 13, a building with a living room facing south is positioned on a plot of land where the road frontage is located on the north side. In this case, the building database holds the location and orientation of the main living space for each building.

[0087] Variant 2 concerns the display of the plan. In other words, the design preferences (tastes) of the building exteriors included in the plan can be changed individually or collectively. Examples of exterior tastes include, but are not limited to, simple modern, simple natural, Japanese modern, and standard. In the examples in Figures 14 and 15, a plan that includes a building with a standard exterior is changed to a plan that includes a building with a simple natural exterior in response to a user's instruction to change the taste. In this case, the building database may include multiple exterior design preferences (exterior drawings) for a single building.

[0088] The above describes specific embodiments of the land and building plan generation method, apparatus, and system according to representative embodiments of the present invention. However, the present invention is not limited to these embodiments, and various design modifications are possible, and these design modifications are also included within the technical scope of the present invention. For example, in this embodiment, the user terminal 3 and the plan generation device 5 were described as separate computers, but the processes performed by the user terminal 3 and the plan generation device 5 may be performed by a single computer. Furthermore, this embodiment and its modified forms may be combined as appropriate. [Explanation of Symbols]
