A building that can be built on the land designated by the user by applying the search process composed of the first to fourth functional units described above to the building stored in the building information storage unit 1B. Therefore, the buildings that meet the user's wishes are narrowed down.

The selection processing unit 13 executes a process of selecting a predetermined number of buildings having a high priority from the buildings obtained as a result of the search by the search processing unit 12 based on a predetermined priority. The priority can be, for example, price, building supplier, and so on.

The generation processing unit 14 generates a three-dimensional image in which the three-dimensional shape of the building selected by the selection processing unit 13 is superimposed on the land on the three-dimensional map of the land designated by the user and its surroundings. To execute.
In this process, the land information storage unit 1A and the map information storage unit 1C are referred to, and for the land specified by the user, map information of the neighborhood including the road facing the land is extracted, and further, on the land in the map. The buildings selected for are piled up.

Specific examples of this process are shown in FIGS. 10 and 11.
FIG. 10 shows a three-dimensional map of the land designated by the user and its surroundings. The map is extracted from the map information storage unit 1C.
When the search processing unit 12 and the selection processing unit 13 search and select a building that matches a predetermined condition, the building is superimposed on the land designated by the user on the map. FIG. 11 shows a three-dimensional image generated by this, and it is possible to easily imagine a state in which a building is superposed on the land specified by the user and the building is actually built on the land specified by the user. It has become like.

Here, when a plurality of buildings are selected, a stereoscopic image is generated for each building.
Further, the stereoscopic image is generated in a state where the tangential direction of the land and the direction of the land, and the road direction of the building and the set direction are matched. By changing the road direction and setting direction of the building within the allowable angle range, if the building fits in the land, the angle of the building is changed within the allowable angle range with respect to the land, and the land becomes A stereoscopic image of the building is generated.

This stereoscopic image may be viewed from various angles based on the operation by the user on the user terminal 2. In this case, the output of the screen on the user terminal 2 is specifically realized by Ajax or the like.
Further, as shown in FIG. 12, optional parts such as a car may be freely selected and arranged in this stereoscopic image.

The communication processing unit 15 is a processing unit that executes data transmission / reception with the user terminal 2 via a network NW such as the Internet.
The communication processing unit 15 can receive information related to the designation of land and transmit information related to a building that can be built on the designated land with the user terminal 2.

The user terminal 2 is a terminal used by a user who searches for desired real estate information by using the system provided by the real estate information search device 1. The user terminal 2 is composed of, for example, a so-called personal computer, a tablet-type terminal or a portable terminal capable of transmitting and receiving data.
Further, the user terminal 2 has a communication processing unit such as a web browser that executes data transmission / reception processing, a display for inputting / outputting data, and an input / output processing unit such as a touch panel or a keyboard.

Next, a series of processes executed by the real estate information retrieval device 1 according to the present embodiment will be described with reference to FIGS. 13 to 15.
First, via a predetermined website or the like, the user terminal 2 receives a request for proposal of a building that can be built on the land together with the designation of the land (S101).

For example, as shown in FIG. 16, the user specifies the land by referring to the land information and the map information stored in the land information storage unit 1A and the map information storage unit 1C to obtain a map in which the land is partitioned. Display and allow the user to specify a predetermined land from the map. Further, in another example, it is also possible to accept the input of the address from the predetermined input form and thereby specify the land specified by the address.
At this time, in addition to the designation of the land, it is also possible to optionally accept the designation of conditions based on the basic information of the building so that the building can be narrowed down by the price range desired by the user or the manufacturer of the building in advance.

In this example, the user is made to specify a predetermined land from the land stored in the land information storage unit 1A and the map information storage unit 1C in advance. It is also possible to register the land information in the land information storage unit 1A and search for a building based on the land information.

When the user specifies the land, the search process for buildings that can be built on the designated land is executed (S102).
Here, FIG. 14 shows the details of the process flow for searching for a building that can be built on the land designated by the user.
First, the extraction processing unit 11 extracts the land information of the land designated by the user from the land information storage unit 1A (S201).

When the land information is extracted, if the condition of the basic information of the building is specified, the search processing unit 12 narrows down the buildings having the basic information desired by the user by the fourth functional unit (S202). .. Here, the land that mainly meets the conditions of user convenience, such as the manufacturer of the building and the price, is narrowed down.
Further, the first functional unit narrows down the buildings having the building-side building conditions that match the land-side building conditions of the land (S203). Here, the information such as the building coverage ratio and floor area ratio determined for each land is compared with the information such as the site area and building area of each building, and the designated land without exceeding the restrictions such as the building coverage ratio and floor area ratio. Buildings that can be built are narrowed down.

Then, for the narrowed-down building by the second functional unit, whether the floor plan shape of the building fits in the land shape in a state where the land direction of the land specified by the user and the setting direction of the building are matched. Whether or not it is determined (S204).
Furthermore, if the floor plan shape of the building does not fit in the land shape when the land direction of the land and the setting direction of the building are matched, the building is within the allowable angle range for the setting direction set for the building. By tilting, it is determined whether or not the floor plan shape of the building fits in the land shape (S205).

As a result, if the floor plan shape of the building does not fit in the land shape even within the allowable angle range set for the building, the building is treated as not satisfying the search condition (S206).
On the other hand, in the processing of S205, when the floor plan shape of the building fits in the land shape in a state where the land direction of the land and the setting direction of the building are matched, and in the processing of S206, the setting direction of the building is an allowable angle. If the floor plan shape of the building fits in the land shape in the state of being tilted within the range of, it is determined that the building satisfies the search condition in the processing by the second functional unit.

Then, for the narrowed-down building by the third functional unit, whether the floor plan shape of the building fits in the land shape in a state where the road direction of the land specified by the user and the road direction of the building match. Whether or not it is determined (S207).
Furthermore, if the floor plan shape of the building does not fit in the land shape when the road direction of the land and the road direction of the building are matched, the road direction of the building is tilted within the allowable angle range. , It is determined whether or not the floor plan shape of the building fits in the land shape (S208).

As a result, if the floor plan shape of the building does not fit in the land shape even within the allowable angle range set for the building, the building is treated as not satisfying the search condition (S209).
On the other hand, in the processing of S207, when the floor plan shape of the building fits in the land shape in a state where the road direction of the land and the road direction of the building are matched, and in the processing of S208, the road direction of the building is allowed to be an allowable angle. If the floor plan shape of the building fits in the land shape in the state of being tilted within the range of, it is determined that the building satisfies the search condition in the processing by the third functional unit.

The order of processing by the first to fourth functional units is not particularly limited to the order described in this example, and may be executed in an order different from that in this example. Further, in other embodiments, only one or a part of the processes by the first to fourth functional units can be executed.

As a result of the search by the search processing unit 12, when the buildings that can be built on the land specified by the user and the buildings that meet the user's wishes are narrowed down, the selection processing unit 13 actually tells the user. As the buildings to be proposed to, a predetermined number of buildings are selected from the buildings that satisfy the search conditions.
In this process, when the number of buildings obtained by the process of S102 is not more than a predetermined number (S103), all the buildings of the predetermined number or less are selected as the buildings to be proposed to the user.

On the other hand, when the number of buildings obtained by the process of S102 is larger than the predetermined number, a predetermined number of buildings having a higher priority is selected based on the predetermined priority (S104).
The priority is, for example, the supplier and price of the building, whether or not the building fits in the land shape by tilting the setting direction and road direction within the allowable angle range, and the size of the tilted angle according to the allowable angle. It can be used as a reference, and the reference conditions can be single or a combination of multiple conditions.

When a predetermined number of buildings that match the search conditions are selected, the generation processing unit 14 displays the three-dimensional shape of the selected building on the three-dimensional map of the land designated by the user and its surroundings. A stereoscopic image superimposed on the top is generated (S105).

Here, the process of generating the stereoscopic image will be described in detail with reference to FIG.
In this process, first, the extraction processing unit 11 extracts the land information of the land designated by the user from the land information storage unit 1A (S301). Further, the extraction processing unit 11 refers to the map information storage unit 1C, and extracts three-dimensional map information of the designated land and its surroundings (S302). Further, the extraction processing unit 11 refers to the building information storage unit 1B, and the building information including the three-dimensional shape of the building selected by the selection processing unit 13 is extracted (S303).

The generation processing unit 14 superimposes the three-dimensional shape of the selected building on the designated land on the three-dimensional map of the land designated by the user and its surroundings (S304). At this time, the generation processing unit 14 determines the land tangential direction, the building road direction, the land land direction, and the building setting direction based on the land tangential direction and the land direction, and the building road direction and the setting direction. Match. In addition, regarding the floor shape of a predetermined building, if the setting direction and road direction of the building are tilted within the range of the setting direction tolerance and road direction tolerance, and the land shape of the specified land fits, the setting is made. Tilt the direction or direction of the building within the range of the direction tolerance and the road direction tolerance, and superimpose the three-dimensional shape of the building on the land so that the building fits on the land.

When a stereoscopic image is generated for all the selected buildings, the stereoscopic image is presented to the user terminal 2 as a building search result. (S106).
FIG. 17 shows an example of the screen on the user terminal 2 at this time.
This screen example shows a case where three buildings are selected by the selection processing unit 13 as buildings that can be built on the designated land, and each of the three buildings selected according to a predetermined priority is the land. It is displayed in a list as three-dimensional images 101, 102, and 103 arranged above. The stereoscopic images 101, 102, and 103 shown in a list can be displayed in a large size in the enlarged display field 104 by selecting any of them. In the example of FIG. 17, the case where the stereoscopic image 101 is enlarged and displayed in the enlarged display field 104 is shown, and it can be seen that the stereoscopic image 101 shown in the list is selected by the dotted line display. ing.

The stereoscopic image 101 in the enlarged display field 104 can be rotated and displayed together with the surrounding map, enlarged / reduced, and the like by a predetermined operation, and can be viewed from various angles.
Further, in this example, a car object 105 is prepared, and it is possible to imagine a case where the object 105 is appropriately arranged and the car is parked on the premises.
Further, when the download button 106 is pressed, the stereoscopic image 101 displayed in the enlarged display field 104 can be taken out as data in a predetermined format.

Further, when the "Display search results further" button 107 is pressed, the buildings searched by the search processing unit 12 and not selected by the selection processing unit 13 are selected based on a predetermined priority. It will be newly displayed.

As a result, the user can grasp what kind of building can be built on the predetermined land by a concrete three-dimensional image. Further, since a predetermined number of such concrete stereoscopic images are displayed as search results and the user is not required to perform complicated operations, it is very easy for the user to understand.

In the fourth functional part of this embodiment, the basic information of the land that can be specified as the search condition by the user includes the surrounding environment such as the distance from the nearest station and whether or not there is a supermarket in the neighborhood, and the price of the land. Etc. may be included. Further, as the price as the search condition, the total price including the land specified by the user and the construction cost of the building may be selected.

In the second embodiment of the present invention, the land desired by the user is searched, and the land is proposed based on the search result.
This second embodiment is realized by the real estate information retrieval device 1 having the same functional unit as that of the first embodiment. That is, also in this example, the real estate information search device 1 includes a land information storage unit 1A, a building information storage unit 1B, a map information storage unit 1C, an extraction processing unit 11, a search processing unit 12, a selection processing unit 13, and a generation processing unit. A functional block including 14 and a communication processing unit 15 is configured. In this example, among the functions executed by each functional unit, the description of the function described in the first embodiment will be omitted. Further, since the configuration and function of the user terminal 2 are the same as those in the first embodiment, the description thereof will be omitted.

Based on the building information extracted by the extraction processing unit 11, the search processing unit 12 refers to the land information storage unit 1A and executes a process of searching for land on which a building designated by the user can be built.
The search processing unit 12 is composed of a first functional unit, a second functional unit, a third functional unit, and a fourth functional unit, and refers to the land information storage unit 1A in response to a search request from the user. Then, the land corresponding to the user's search request is searched.

Specifically, the first functional unit determines whether or not the land stored in the land information storage unit 1A has land-side building conditions that match the building-side building conditions of the building specified by the user. to decide.

In addition, the second functional unit sets the building specified by the user for the land stored in the land information storage unit 1A based on the floor plan shape of the building specified by the user and the land shape of the land. With the direction and the land direction of the land matched, it is determined whether or not the building specified by the user fits in the land. This second functional unit can further determine whether or not the building fits within an acceptable angle with respect to the set direction set for the building when determining whether or not the building fits on the land.

In addition, the third functional unit has the floor plan of the land stored in the land information storage unit 1A in a state where the road direction of the building specified by the user and the road direction of the land are matched. Determine if the shape fits into the land shape of the land. This third functional unit may further determine whether the building will fit in a state of being tilted within an acceptable angle with respect to the road direction of the building when determining whether the building will fit on the land. can.

Further, the fourth functional unit determines whether or not the land stored in the land information storage unit 1A has matching basic information based on information such as a price arbitrarily input by the user as a search condition. to decide.

The building designated by the user can be constructed by applying the search process composed of the first to fourth functional units described above to the land stored in the land information storage unit 1A. Therefore, the land that meets the user's wishes is narrowed down.

The generation processing unit 14 generates a three-dimensional image in which the three-dimensional shape of the building specified by the user is superimposed on the land on the three-dimensional map of the land selected by the selection processing unit 13 and its surroundings. To execute.
In this process, the land information storage unit 1A and the map information storage unit 1C are referred to, and for the land selected by the selection processing unit 13, map information of the neighborhood including the road facing the land is extracted, and further, in the map. The building specified by the user is overlaid on the land.

Next, a series of processes executed by the real estate information retrieval device 1 according to the present embodiment will be described with reference to FIGS. 18 and 19.
First, a request for proposal of land on which the building can be constructed is received from the user terminal 2 together with the designation of the building via a predetermined website or the like (S401).
For example, the building is designated by presenting the building stored in the building information storage unit 1B to the user in a selectable manner and designating the building from among them.

When the user specifies a building, a search process for land on which the specified building can be built is executed (S402).
At this time, in addition to the designation of the building, it is also possible to optionally accept the designation of conditions based on the basic information of the land so that the land can be narrowed down in advance by the price range or address desired by the user.
In this example, the user is made to specify the building from the building stored in the building information storage unit 1B in advance, but the building information is received from the user and the building information is transmitted to the building information storage unit 1B. You can also register and search for land based on the building information.

Here, FIG. 19 shows the details of the process flow for searching for land on which the building designated by the user can be built.
First, the extraction processing unit 11 extracts the building information of the building designated by the user from the building information storage unit 1B (S501).

When the building information is extracted, the search processing unit 12 narrows down the land having the basic information desired by the user by the fourth functional unit (S502). Here, land that mainly meets the conditions of user convenience, such as land price and address, is narrowed down.
Further, the first functional unit narrows down the land having the land-side building conditions that match the building-side building conditions of the building (S503). Here, the information such as the building coverage ratio and floor area ratio determined for each land is compared with the information such as the site area and building area for each building, and the specified building does not exceed the restrictions such as the building coverage ratio and floor area ratio. The land that can be built is narrowed down.

Then, with respect to the narrowed down land by the second functional part, is the land shape that the floor plan shape of the building fits in the state where the setting direction of the building specified by the user and the land direction of the land are matched? Whether or not it is determined (S504).
Furthermore, if the floor plan shape of the building does not fit in the land shape when the setting direction of the building and the land direction of the land are matched, the setting direction set for the building is within the allowable angle range. , It is determined whether or not the floor plan shape of the building fits in the land shape (S505).

As a result, if the floor plan shape of the building does not fit in the land shape even within the allowable angle range set for the building, the land is treated as not satisfying the search condition (S506).
On the other hand, in the processing of S504, when the floor plan shape of the building fits in the land shape with the land direction of the land and the setting direction of the building matched, and in the processing of S505, the setting direction of the building is allowed. If the floor plan shape of the building fits in the land shape in the state of being tilted within the range of, the land is judged to satisfy the search condition in the processing by the second functional unit.

Then, with respect to the narrowed down land by the third functional part, is the land shape that the floor plan shape of the building fits in the state where the road direction of the building specified by the user and the tangential direction of the land match? Whether or not it is determined (S507).
Furthermore, if the floor plan shape of the building does not fit in the land shape when the road direction of the building and the road contact direction of the land are matched, the building is tilted within the allowable angle in the road direction. , It is determined whether or not the floor plan shape of the building fits in the land shape (S508).

As a result, if the floor plan shape of the building does not fit in the land shape even within the allowable angle range set for the building, the land is treated as not satisfying the search condition (S509).
On the other hand, in the processing of S507, when the floor plan shape of the building fits in the land shape in a state where the road direction of the building and the road direction of the land are matched, and in the processing of S508, the permissible angle of the building in the road direction. If the floor plan shape of the building fits in the land shape in the state of being tilted within the range of, the land is judged to satisfy the search condition in the processing by the third functional unit.

As a result of the search by the search processing unit 12, when the building specified by the user is the land that can be built and the land that meets the user's wishes is narrowed down, the selection processing unit 13 actually tells the user. As the land to be proposed to, a predetermined number of lands are selected from the lands that meet the search conditions.
In this process, when the number of lands obtained by the process of S402 is less than or equal to a predetermined number (S403), all the lands less than or equal to the predetermined number are selected as the land to be proposed to the user.

On the other hand, when the number of lands obtained by the treatment of S402 is larger than the predetermined number, a predetermined number of lands having a higher priority is selected based on the predetermined priority (S404).
The priority can be based on, for example, whether or not the building shape fits into the land shape by tilting the angle based on the land price and the allowable angle of the building, and the size of the tilted angle within the allowable angle range. , The reference condition can be single or a combination of multiple conditions.

When a predetermined number of lands that match the search conditions are selected, the generation processing unit 14 displays the three-dimensional shape of the building specified by the user on the selected land and its surroundings on the three-dimensional map. A stereoscopic image superimposed on is generated (S405).

Here, the process of generating the stereoscopic image will be described in detail with reference to FIG.
In this process, first, the extraction processing unit 11 extracts the building information including the three-dimensional shape of the building designated by the user from the building information storage unit 1B (S601). Further, the extraction processing unit 11 refers to the map information storage unit 1C, and extracts three-dimensional map information of the selected land and its surroundings (S602). Further, the extraction processing unit 11 refers to the land information storage unit 1A, and the land information of the land selected by the selection processing unit 13 is extracted (S603).

The generation processing unit 14 superimposes the three-dimensional shape of the building designated by the user on the selected land on the three-dimensional map of the selected land and its surroundings (S604). At this time, the generation processing unit 14 determines the land tangential direction, the building road direction, the land land direction, and the building setting direction based on the land tangential direction and the land direction, and the building road direction and the setting direction. Match. In addition, when the floor shape of the specified building fits in the land shape of the selected land by tilting the setting direction and road direction of the building within the range of the setting direction tolerance and road direction tolerance. In order to, the direction or direction of the building is tilted within the range of the set direction tolerance and the road direction tolerance, and the three-dimensional shape of the building is overlapped on the land so that the building fits in the land.

When a stereoscopic image is generated for all the selected lands, the stereoscopic image is presented to the user terminal 2 as a land search result. (S406).
The screen on the user terminal 2 at this time is the same as in FIG. 17 described in detail in the first embodiment, and the three-dimensional shape of the designated building is superimposed on the searched and selected land. It is the one displayed.

According to this embodiment, it is possible to search for land on which the building can be built from the buildings designated by the user. Then, as in the case of the first embodiment described above, the user can grasp how the building is constructed on the land with a concrete image by the three-dimensional image.
