In recent years, in the fields of AR (Augmented Reality) and autonomous driving, a self-position estimation method called VPS has been developed and put into practical use. VPS is a technology that aligns virtual and real spaces by comparing camera images with scanned spatial information (3D map including 3D point cloud information).

In conventional VPS technology, detailed location information that can uniquely identify the 3D map to be used is not stored together with the 3D map. Additionally, there is no mechanism to automatically select the 3D map to use based on location information. As a result, the efficiency when selecting a 3D map on a VPS has deteriorated. For example, when a relatively large space is targeted, it is necessary to divide the 3D map because the amount of data becomes enormous if it is made into one 3D map. If position information is not attached to the 3D map, the act of selecting a map will occur each time the user moves from place to place, resulting in a decrease in UX (User Experience). Furthermore, for example, when targeting an environment with multiple rooms with the same design, if only matching with camera images is used, the wrong 3D map may be selected because the features are similar.

In the system 10 according to this embodiment, for example, detailed position information data is added to the 3D map. In conventional VPS technology, GPS (latitude, longitude, altitude) information is stored together with the map, but if only one piece of coordinate information is used, all maps that apply near that coordinate will be selected as candidates. In the system 10, the range in real space of the three-dimensional area to which the 3D map corresponds is saved together with the 3D map. As a specific example, in the system 10, eight vertex coordinates of a 3D map are applied to real space and saved. This makes it possible to select a specific point cloud map that applies to the location information of the terminal. Additionally, the system 10 introduces a mechanism for selecting 3D maps that utilizes location information. For example, in the system 10, position information of a terminal is acquired using GPS, beacon ID, PDR (pedestrian dead reckoning), etc., and a 3D map that matches the acquired position information is selected. Furthermore, a 3D map adjacent to the 3D map is also selected. When using a VPS, it is likely that the user will be constantly moving, so by selecting adjacent 3D maps as well, the efficiency of the VPS can be increased.

Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. Furthermore, not all combinations of features described in the embodiments are essential to the solution of the invention.

FIG. 1 schematically depicts an example of a system 10. The system 10 includes a management device 100 and a communication terminal 200. Although one communication terminal 200 is illustrated in FIG. 1, the system 10 may include a plurality of communication terminals 200.

System 10 may implement a VPS. The management device 100 may manage 3D maps used for VPS. The management device 100 may manage 3D maps registered from the outside. The management device 100 may generate a 3D map. The management device 100 may generate a 3D map based on a plurality of images whose positions have been specified.

The communication terminal 200 identifies the position and orientation of the user 202 of the communication terminal 200 using the 3D map received from the management device 100 and the captured image captured by the camera included in the communication terminal 200. Communication terminal 200 may further specify the positional relationship between communication terminal 200 and surrounding objects.

The management device 100 and the communication terminal 200 may communicate via the network 20. Network 20 may include a mobile communications network. The mobile communication network is compliant with any of the following communication methods: LTE (Long Term Evolution) communication method, 5G (5th Generation) communication method, 3G (3rd Generation) communication method, and 6G (6th Generation) communication method. You can. Network 20 may include the Internet. Network 20 may include a cloud.

The management device 100 may be connected to the network 20 by wire. The management device 100 may be wirelessly connected to the network 20. The management device 100 is connected to the network 20 via a wireless base station, for example. The management device 100 is connected to the network 20 via a Wi-Fi (registered trademark) (Wireless Fidelity) access point, for example.

Communication terminal 200 may be wirelessly connected to network 20 . Communication terminal 200 is connected to network 20 via a wireless base station, for example. Communication terminal 200 is connected to network 20 via a Wi-Fi access point, for example.

The management device 100 may be composed of one physical device or a plurality of physical devices. The management device 100 is placed in a mobile communication network, for example. The management device 100 is placed, for example, in a core network in a mobile communication network. The management device 100 may be placed in MEC (Multi access Edge Computing, Mobile Edge Computing). The management device 100 is placed in a cloud, for example. The management device 100 is placed on the Internet, for example.

The communication terminal 200 may be any terminal as long as it is equipped with a camera and can execute VPS. The camera of communication terminal 200 may be a built-in type or an external type. For example, communication terminal 200 is a smartphone. For example, communication terminal 200 is a wearable terminal. For example, the communication terminal 200 is AR (Augmented Reality) glasses.

Communication terminal 200 may have a positioning function. The communication terminal 200 performs GNSS (Global Navigation Satellite System) positioning such as GPS (Global Positioning System) positioning, for example. The communication terminal 200 performs, for example, NW (NetWork) positioning. Examples of NW positioning include cell positioning, Wi-Fi (registered trademark) positioning, and the like. The communication terminal 200 performs, for example, PDR (pedestrian dead reckoning). For example, the communication terminal 200 grasps its own position by appropriately performing GNSS positioning, and when it becomes unable to perform GNSS positioning due to moving into a building or underground, it uses PDR to determine its own position. Continue to understand.

The management device 100 according to the present embodiment associates and stores range information indicating the range of the corresponding three-dimensional area 310 in real space with each of a plurality of 3D maps, each of which corresponds to a three-dimensional area 310 in real space. do. Real space is real space, not virtual space. Then, management device 100 selects one of the plurality of 3D maps and transmits it to communication terminal 200 based on the plurality of range information and terminal position information indicating the position of the communication terminal.

In conventional VPS technology, a single location (latitude, longitude, altitude) is associated with a 3D map, but in that case, it is difficult to accurately identify the 3D map that corresponds to the location of the communication terminal 200. For example, a plurality of 3D maps whose associated positions are close to the position of the communication terminal 200 have become selection candidates. In contrast, according to the management device 100 according to the present embodiment, range information allows selection of a specific 3D map that applies to the location of the communication terminal 200.

The communication terminal 200 transmits terminal location information indicating the location of the communication terminal 200 to the management device 100, is selected by the management device 100 using the transmitted terminal location information, receives the transmitted 3D map, and uses the received 3D map. Run VPS using maps.

For example, in response to receiving an instruction from the user 202, the communication terminal 200 transmits terminal position information of the communication terminal 200 and 3D map request information to the management device 100. In response to the request information received from the communication terminal 200, the management device 100 transmits to the communication terminal 200 a 3D map corresponding to range information including the position indicated by the terminal position information received from the communication terminal 200. In this way, according to the management device 100, a 3D map applicable to the location of the communication terminal 200 can be immediately transmitted to the communication terminal 200.

Further, the communication terminal 200 transitions to the VPS execution state, for example, in response to receiving an instruction from the user 202. In the VPS execution state, the communication terminal 200 periodically transmits terminal location information of the communication terminal 200 to the management device 100. If range information including the position indicated by the received terminal position information exists, management device 100 transmits a 3D map corresponding to the range information to communication terminal 200. In this way, according to the management device 100, when the moving communication terminal 200 enters the three-dimensional area 310 in which the 3D map is registered, the 3D map is transmitted to the communication terminal 200. be able to.

In addition to the 3D map corresponding to the 3D area 310 where the communication terminal 200 is located, the management device 100 transmits to the communication terminal 200 a 3D map corresponding to the 3D area 310 adjacent to the 3D area 310. good. When using a VPS, the user 202 is likely to constantly move, and there is a high possibility that the user 202 will move from the three-dimensional area 310 where the user is currently located to an adjacent three-dimensional area 310. When transmitting a 3D map to the communication terminal 200 after moving to an adjacent 3D area 310, there is a possibility that a time lag will occur before VPS can be executed within the 3D area 310. By transmitting the 3D map to the communication terminal 200, time lag can be eliminated and the efficiency of VPS can be improved.

The selection of the 3D map may be performed at the initiative of the user 202. For example, the user 202 accesses the management device 100 through the communication terminal 200, selects a 3D map corresponding to the three-dimensional area 310 where the user 202 is located from among a plurality of 3D maps, and requests the management device 100 to select the 3D map corresponding to the three-dimensional area 310 where the user 202 is located. Management device 100 transmits the requested 3D map to communication terminal 200. At this time, in addition to the requested 3D map, the management device 100 may transmit to the communication terminal 200 a 3D map corresponding to a 3D area 310 adjacent to the 3D area 310 to which the 3D map corresponds. .

FIG. 2 schematically shows an example of range information 400. The range information 400 may be any information as long as it indicates the range of the corresponding three-dimensional area 310 in real space.

FIG. 2 illustrates a case where the three-dimensional area 310 has a rectangular shape. When the three-dimensional area 310 has a rectangular shape, the range information 400 includes, for example, the minimum and maximum values of the X-axis and the minimum and maximum values of the Y-axis of the three-dimensional area 310 on the coordinate space in real space. , a minimum value and a maximum value of the Z axis. In the example shown in FIG. 2, the range information 400 includes the coordinates of eight vertices of the rectangular range information 400. As a result, the range information 400 can indicate the range of the three-dimensional area 310 in real space with a very small amount of data, and can indicate when the communication terminal 200 enters the three-dimensional area 310 and from the three-dimensional area 310. It is possible to reduce the calculation load for detecting the appearance.

Note that the shape of the three-dimensional area 310 is not limited to a rectangular shape, but may be any shape. When the shape of the three-dimensional area 310 is a shape other than a rectangular shape, the range information may be information that allows the range of the three-dimensional area 310 to be specified in accordance with the shape of the three-dimensional area 310. For example, if the three-dimensional area 310 has a spherical shape, the range information may include information about the center point and radius of the three-dimensional area 310.

FIG. 3 schematically shows an example of an area group 300 of a three-dimensional area 310. Here, a case is illustrated in which a plurality of three-dimensional areas 310 are arranged consecutively. The management device 100 stores 3D maps corresponding to each of the plurality of three-dimensional areas 310.

FIG. 4 is an explanatory diagram for explaining an example of a 3D map transmission process by the management device 100. Here, the area group 300 illustrated in FIG. 3 is illustrated as viewed from above, and an example is given in which terminal position information and 3D map request information are received from the communication terminal 200 currently located in the area 312. explain.

The management device 100 identifies the current area 312 corresponding to the range information including the position indicated by the terminal location information among the plurality of range information. Furthermore, the management device 100 identifies a related area 314 related to the current area 312.

For example, the management device 100 identifies the related area 314 based on the positional relationship with the current area 312. In the example shown in FIG. 4, the management device 100 identifies four three-dimensional areas 310 adjacent to the current area 312 as related areas 314. The management device 100 then transmits the 3D map corresponding to the current area 312 and the four 3D maps corresponding to the four related areas 314 to the communication terminal 200. Note that although an example has been described here in which the management device 100 specifies the three-dimensional area 310 horizontally adjacent to the current area 312 as the related area 314, the present invention is not limited to this. The management device 100 may further specify four three-dimensional areas 310 diagonally adjacent to the current area 312 as related areas 314. Furthermore, the management device 100 may specify a three-dimensional area 310 located within a predetermined distance from the current area 312 as the related area 314.

Management device 100 may identify related area 314 using terminal-related information related to communication terminal 200 in addition to the positional relationship with current area 312 . For example, among the three-dimensional areas 310 adjacent to the current area 312, the management device 100 identifies the three-dimensional area 310 located ahead in the movement direction of the communication terminal 200 as the related area 314. For example, among the three-dimensional areas 310 adjacent to the current area 312, the management device 100 identifies the three-dimensional area 310 located beyond the direction in which the user 202 of the communication terminal 200 is facing, as the related area 314.

The management device 100 may register a related 3D map in advance for each of the plurality of 3D maps, and store the related 3D maps in association with each other. In this case, after identifying the current area 312, the management device 100 identifies a related 3D map that is registered in association with the current area 312, and compares the related 3D map and the 3D map corresponding to the current area 312. It is transmitted to the communication terminal 200.

Registration of related 3D maps to the 3D map may be performed by an administrator of the system 10 or the like. For example, the administrator of the system 10 registers, for each of the plurality of three-dimensional areas 310, a three-dimensional area 310 that may be moved from the three-dimensional area 310 as a related area in the management device 100. The management device 100 registers the 3D map corresponding to the three-dimensional area 310 and the 3D map corresponding to the related area in association with each other.

The administrator of the system 10, for example, checks whether it is physically possible to move from one three-dimensional area 310 to another three-dimensional area 310, and if it is possible to move, move the related area. judge. For example, the administrator of the system 10 determines that an area is a related area when the degree of association between one three-dimensional area 310 and another three-dimensional area 310 is high. Note that such a determination may be performed mainly by the management device 100. For example, the management device 100 displays the position of one three-dimensional area 310, a plurality of images taken of one three-dimensional area 310, the position of another three-dimensional area 310, and images of another three-dimensional area 310. By analyzing a plurality of images, it is determined whether one three-dimensional area 310 and another three-dimensional area 310 are related. For example, the management device 100 analyzes whether it is possible to move from one three-dimensional area 310 to another three-dimensional area 310, the relationship between one three-dimensional area 310 and another three-dimensional area 310, etc. Judgment can be made by

FIG. 5 is an explanatory diagram for explaining an example of a 3D map transmission process by the management device 100. Here, a case will be described in which the plurality of three-dimensional areas 310 are not continuous.

The management device 100 identifies the current area 312 corresponding to the range information including the position indicated by the terminal location information among the plurality of range information. Furthermore, the management device 100 identifies a related area 314 related to the current area 312. In the example shown in FIG. 5, the management device 100 identifies two three-dimensional areas 310 located within a predetermined distance from the current area 312 as related areas 314. Management device 100 transmits a 3D map corresponding to current area 312 and two 3D maps corresponding to two related areas 314 to communication terminal 200.

3 to 5 illustrate the case where a plurality of three-dimensional areas 310 are arranged in the horizontal direction. For example, if the target is a building with multiple floors, multiple three-dimensional areas 310 are arranged on each floor. The three-dimensional area 310 may be arranged not only in the horizontal direction but also in the vertical direction. For example, in an open space such as a city, a plurality of three-dimensional areas 310 may be arranged horizontally and stacked vertically. In this case, the management device 100 transmits to the communication terminal 200 a 3D map corresponding to the current area 312 where the communication terminal 200 is located and a 3D map corresponding to the 3D area 310 located above the current area 312. It's fine. Furthermore, when transmitting the 3D map corresponding to the related area 314 to the communication terminal 200, the management device 100 also transmits the 3D map corresponding to the three-dimensional area 310 located above the related area 314 to the communication terminal 200. You may do so.

FIG. 6 schematically shows an example of the functional configuration of the management device 100. The management device 100 includes a storage section 110, a registration section 120, a map generation section 122, a terminal related information acquisition section 130, a map selection section 140, a map transmission section 142, and a deletion instruction transmission section 144. Note that it is not essential that the management device 100 include all of these.

The storage unit 110 stores various information. The storage unit 110 may include a map storage unit 112 and a terminal-related information storage unit 114. Note that it is not essential that the storage unit 110 include all of these.

The registration unit 120 executes registration of various information. For example, the registration unit 120 registers a plurality of 3D maps, each of which corresponds to a plurality of three-dimensional areas 310 in real space. The registration unit 120 registers range information indicating the range of the corresponding three-dimensional area 310 in real space in association with each of the plurality of 3D maps. For example, the registration unit 120 receives and registers a 3D map and range information from an external device. The registration unit 120 causes the map storage unit 112 to store the registered 3D map and range information.

The registration unit 120 may register AR content to be displayed on the communication terminal 200. The registration unit 120 may store AR content to be displayed on the communication terminal 200 in the three-dimensional area 310 in the map storage unit 112 in association with the 3D map corresponding to the three-dimensional area 310.

The map generation unit 122 generates a 3D map. The map generation unit 122 generates a 3D map, for example, based on a plurality of images whose positions are specified and stored in the storage unit 110.

The map generation unit 122 may acquire 3D area information of a target 3D area in the real world, and generate a 3D map corresponding to the 3D area based on the 3D area information. For example, the map generation unit 122 may generate one 3D map that covers the entire target three-dimensional area in the real world, or divide the three-dimensional area into a plurality of three-dimensional areas. multiple 3D maps covering multiple 3D areas. For example, when the map generation unit 122 generates one 3D map for a target three-dimensional area in the real world, and the data size of the 3D map becomes larger than a predetermined threshold, A target three-dimensional area is divided into a plurality of three-dimensional areas, and a plurality of 3D maps covering the divided three-dimensional areas are generated. When dividing one three-dimensional area into a plurality of three-dimensional areas, the map generation unit 122 may divide the area according to divisions in real space. The map generation unit 122 may, for example, divide the map by categories such as roads and buildings, or by hierarchy of buildings. The map generation unit 122 may generate range information for each of the plurality of generated 3D maps, and store the range information in the map storage unit 112 in association with each other.

The terminal-related information acquisition unit 130 acquires terminal-related information related to the communication terminal 200. The terminal-related information acquisition unit 130 may receive terminal-related information from the communication terminal 200. The terminal-related information acquisition unit 130 causes the terminal-related information storage unit 114 to store the acquired terminal-related information.

The terminal related information acquisition unit 130 acquires terminal position information of the communication terminal 200, for example. The terminal-related information acquisition unit 130 acquires, for example, movement direction information indicating the movement direction of the communication terminal 200. The communication terminal 200 generates movement direction information using detection results by an acceleration sensor and a gyro sensor included in the communication terminal 200, results of time-series positioning processing, and the like.

The terminal related information acquisition unit 130 acquires, for example, user direction information indicating the direction in which the user 202 of the communication terminal 200 is facing. Communication terminal 200 generates user direction information based on, for example, posture information of communication terminal 200 and the positional relationship between communication terminal 200 and user 202.

The terminal-related information acquisition unit 130 acquires, for example, behavior history information indicating the behavior history of the user 202 of the communication terminal 200. The action history information may include the movement history of the user 202. The action history information may include a payment history by the user 202.

The communication terminal 200 generates moving speed information using, for example, detection results by an acceleration sensor and a speed sensor included in the communication terminal 200, results of time-series positioning processing, and the like.

The map selection unit 140 selects the information stored in the map storage unit 112 based on the terminal location information of the communication terminal 200 acquired by the terminal related information acquisition unit 130 and the plurality of range information stored in the map storage unit 112. Select one of the multiple 3D maps available. Map transmitter 142 transmits the 3D map selected by map selector 140 to communication terminal 200.

The map selection unit 140 selects, for example, a 3D map corresponding to range information including the location indicated by the terminal location information. Thereby, a 3D map corresponding to the three-dimensional area 310 in which the communication terminal 200 is located can be transmitted to the communication terminal 200, and the communication terminal 200 can be caused to appropriately execute VPS. If another three-dimensional area 310 is placed above the three-dimensional area 310 corresponding to the range information including the position indicated by the terminal position information, the map selection unit 140 selects a map corresponding to the other three-dimensional area 310. You may also select a 3D map to use.

The map selection unit 140 monitors the terminal position information of the communication terminal 200 that the terminal-related information acquisition unit 130 receives from the communication terminal 200, so that the communication terminal 200 can select any three-dimensional area in which a 3D map is registered. 310, this may be detected. Then, in response to the communication terminal 200 entering the three-dimensional area 310, the map selection unit 140 may select the 3D map corresponding to the three-dimensional area 310 in which the communication terminal 200 has entered. Thereby, an appropriate 3D map can be transmitted to the communication terminal 200 at an appropriate timing without making the user 202 of the communication terminal 200 aware of it. Note that the map selection unit 140 may accept a designation of a 3D map by the user 202 of the communication terminal 200. For example, the map selection unit 140 selects a 3D map specified by the user 202 of the communication terminal 200 from among the plurality of 3D maps.

In addition to the 3D map corresponding to the range information including the position indicated by the terminal location information, the map selection unit 140 selects 3D maps adjacent to the 3D area 310 (sometimes referred to as the current area) corresponding to the 3D map. A 3D map (sometimes referred to as an adjacent 3D map) corresponding to the dimensional area 310 (sometimes referred to as an adjacent area) may be selected. In this case, the map transmitter 142 may transmit the 3D map selected by the map selector 140 and the adjacent 3D map to the communication terminal 200. The map selection unit 140 may identify an adjacent area adjacent to the current area using the positional relationship of the plurality of three-dimensional areas 310 that can be specified by the plurality of range information stored in the map storage unit 112. For example, the map selection unit 140 identifies a three-dimensional area 310 that is continuous in the horizontal direction with respect to the current area as an adjacent area. The map selection unit 140 identifies, for example, a three-dimensional area 310 that is continuous in the horizontal direction with respect to the current area, and a three-dimensional area 310 that is continuous in the diagonal direction with respect to the current area, as adjacent areas. Note that the map storage unit 112 may previously register adjacent three-dimensional areas 310 for each of the plurality of three-dimensional areas 310. The map selection unit 140 may identify the adjacent area by referring to information about the three-dimensional area 310 adjacent to the current area, which is registered in advance for the current area. Further, the map storage unit 112 may previously register adjacent 3D maps for each of the plurality of 3D maps. After identifying the 3D map corresponding to the current area, the map selection unit 140 may select an adjacent 3D map that is registered in advance with respect to the 3D map. There is a relatively high possibility that the user 202 currently located in the area will move to an adjacent area, so by transmitting a 3D map to the communication terminal 200 in advance, VPS can be executed immediately after the user 202 moves to the adjacent area. can be started.

In addition to the 3D map corresponding to the range information including the position indicated by the terminal position information, the map selection unit 140 selects a three-dimensional area 310 (hereinafter referred to as a destination area) to which the communication terminal 200 may move from the current area. You may select a 3D map (sometimes referred to as a destination 3D map) corresponding to the destination 3D map. In this case, the map transmitter 142 may transmit the 3D map selected by the map selector 140 and the destination 3D map to the communication terminal 200. In addition to the 3D map corresponding to the 3D area 310 where the communication terminal 200 is currently located, a 3D map corresponding to the 3D area 310 from which the communication terminal 200 may move is transmitted to the communication terminal 200. By doing this, compared to the case where the communication terminal 200 transmits the 3D map after entering the three-dimensional area 310, a time lag can be eliminated, and VPS can be executed immediately after the communication terminal 200 moves.

The map selection unit 140 selects a destination 3D map, for example, with a three-dimensional area 310 located within a predetermined distance from the current area as the destination area. As a result, if there is a three-dimensional area 310 in which a 3D map is registered near the current area, the 3D map corresponding to the three-dimensional area 310 can be transmitted to the communication terminal 200 in advance, and the communication terminal 200 Compared to the case where the data is transmitted after moving from the current area to the three-dimensional area 310, the time lag can be eliminated.

The map storage unit 112 may store destination map information indicating a destination 3D map in association with each of the plurality of 3D maps. In this case, the map selection unit 140 may select the destination 3D map indicated by the destination map information of the 3D map corresponding to the range information including the position indicated by the terminal location information. The map storage unit 112 stores, for each of the plurality of 3D maps, destination map information indicating a destination 3D map determined by a person or identified based on image analysis results, so that the current area is It is possible to transmit in advance to the communication terminal 200 a 3D map corresponding to the three-dimensional area 310 in which the communication terminal 200 in which the communication terminal 200 is located is likely to move.

The map selection unit 140 may specify the destination area based on the terminal-related information stored in the terminal-related information storage unit 114.

For example, the map selection unit 140 selects the destination 3D map by setting the three-dimensional area 310 existing in the movement direction indicated by the movement direction information as the movement destination area with the current area as a reference. Since the user 202 is more likely to move in the moving direction indicated by the moving direction information than in other directions, a 3D map of the 3D area 310 in which the user 202 is likely to move is prepared in advance. It can be transmitted to the communication terminal 200.

For example, the map selection unit 140 selects the destination 3D map by setting the three-dimensional area 310 existing in the direction indicated by the user direction information as the destination area with respect to the current area. Since the user 202 is likely to move in the direction in which the user 202 is facing, a 3D map of the three-dimensional area 310 in which the user 202 is likely to move can be transmitted to the communication terminal 200 in advance.

For example, the map selection unit 140 selects a destination 3D map corresponding to a destination area determined based on the destination of the user 202 estimated based on the action history information. The map selection unit 140 determines the destination area based on the destination of the user 202 estimated from the movement history of the user 202, for example. The map selection unit 140 may estimate the destination from the movement history using existing technology. For example, the map selection unit 140 identifies the lifestyle pattern of the user 202 such as commuting to work or school from the long-term movement history of the user 202, and specifies the destination of the user 202 according to the lifestyle pattern. For example, the map selection unit 140 may estimate the destination of the user 202 from the short-term movement history of the user 202. Since the destination of the user 202 has a correlation with the action history of the user 202, a 3D map of the 3D area 310 where the user 202 is likely to move can be sent to the communication terminal 200 in advance.

For example, the map selection unit 140 selects a destination 3D map corresponding to the destination area determined based on the destination indicated by the destination information. For example, the map selection unit 140 selects, as the destination 3D map, a 3D map corresponding to range information including the destination indicated by the destination information. Thereby, it is possible to put the VPS into a state where the user 202 can execute the VPS at the destination before the user 202 arrives at the destination. Further, the map selection unit 140 selects, for example, a 3D map corresponding to the three-dimensional area 310 existing on the route from the current location of the user 202 to the destination indicated by the destination information as the destination 3D map. Thereby, the VPS can be executed without a time lag occurring until the user 202 moves to the destination.

The map selection unit 140 may adjust the number of selected destination 3D maps based on the movement speed information. For example, the map selection unit 140 selects more destination 3D maps as the moving speed indicated by the moving speed information is faster. As a specific example, if the moving speed indicated by the moving speed information is slower than the first threshold, the map selection unit 140 selects one 3D map of the three-dimensional area 310 closest to the current area, If it is faster than the threshold, the 3D map of the three-dimensional area 310 closest to the current area and the 3D map of the next closest three-dimensional area 310 are selected. Furthermore, if the moving speed indicated by the moving speed information is slower than the first threshold, the map selection unit 140 selects one 3D map of the three-dimensional area 310 closest to the current area, and If it is fast and slower than the second threshold which indicates a value faster than the first threshold, the 3D map of the three-dimensional area 310 closest to the current area and the 3D map of the next closest three-dimensional area 310 are selected and moved. If the speed is faster than the second threshold, a 3D map of the 3D area 310 closest to the current area, a 3D map of the next closest 3D area 310, and a 3D map of the next closest 3D area 310 , select. If the user 202 is riding a vehicle such as a bicycle and moving at a fast speed, the user 202 may pass through the three-dimensional area 310 closest to the current area in a short time and end up reaching the next closest three-dimensional area 310. There is sex. According to the map selection unit 140, even in such a case, the VPS can be made executable without any time lag.

The map selection unit 140 may select a 3D map further based on the category of the three-dimensional area 310. Examples of categories of the three-dimensional area 310 include roads, buildings, and the like. For example, if the current area of communication terminal 200 is a road, map selection unit 140 identifies an adjacent area along the road and selects an adjacent 3D map. For example, if the current area of the communication terminal 200 is a road, the map selection unit 140 identifies a destination area along the road and selects a destination 3D map. For example, if the current area of the communication terminal 200 is a road and there is a three-dimensional area 310 whose category is a building in the direction indicated by the user direction information from the position of the communication terminal 200, the map selection unit 140 selects the three-dimensional Select the 3D map of area 310.

After the map transmitting unit 142 transmits the 3D map to the communication terminal 200, the deletion instruction transmitting unit 144 transmits an instruction to delete the 3D map to the communication terminal 200 in response to the communication terminal 200 satisfying a predetermined condition. Send to. For example, the deletion instruction transmitting unit 144 may cause the map transmitting unit 142 to transmit a 3D map corresponding to the one three-dimensional area 310 to the communication terminal 00 due to the communication terminal 200 being located within the one three-dimensional area 310. After that, when the communication terminal 200 moves outside the one three-dimensional area 310, the communication terminal 200 is provided with the 3D image corresponding to the one three-dimensional area 310 in response to the predetermined condition being satisfied. Submit a deletion instruction to delete the map.

For example, when the communication terminal 200 moves out of the one three-dimensional area and then moves away from the one three-dimensional area 310 by a predetermined distance or more, the deletion instruction transmitter 144 deletes the one. A deletion instruction to delete the 3D map corresponding to the 3D area 310 is transmitted to the communication terminal 200. This allows the communication terminal 200 to delete the 3D map when there is a high possibility that the user 202 of the communication terminal 200 will not return to the first three-dimensional area 310.

For example, in a case where a plurality of other three-dimensional areas 310 are consecutive to the one three-dimensional area 310, the deletion instruction transmitting unit 144 deletes the information after the communication terminal 200 moves outside the one three-dimensional area. , when the communication terminal 200 leaves the three-dimensional area 310 adjacent to the one three-dimensional area 310, transmits to the communication terminal 200 a deletion instruction to delete the 3D map corresponding to the one three-dimensional area 310. . Furthermore, for example, when the one three-dimensional area 310 is connected to a plurality of other three-dimensional areas 310, the deletion instruction transmitting unit 144 may cause the communication terminal 200 to move outside the one three-dimensional area. After that, if the communication terminal 200 enters a three-dimensional area 310 that is two or more places away from the one three-dimensional area 310, it communicates a deletion instruction to delete the 3D map corresponding to the one three-dimensional area 310. Send to terminal 200. This allows the communication terminal 200 to delete the 3D map when there is a high possibility that the user 202 of the communication terminal 200 will not return to the first three-dimensional area 310.

For example, when it is detected that the user 202 of the communication terminal 200 gets on a vehicle after the communication terminal 200 moves outside the one three-dimensional area 310, the deletion instruction transmitting unit 144 deletes the one three-dimensional area. A deletion instruction to delete the 3D map corresponding to 310 is transmitted to the communication terminal 200. For example, when the communication terminal 200 moves outside the three-dimensional area 310 and detects that the user 202 of the communication terminal 200 gets on a bus, taxi, etc. A deletion instruction to delete the 3D map corresponding to the 3D area 310 is transmitted to the communication terminal 200. For example, the deletion instruction transmitting unit 144 may detect that the user 202 has taken a bus or a taxi based on the payment history of the user 202 included in the action history information acquired by the terminal-related information acquiring unit 130.

Next, the flow of processing for transmitting a 3D map to the communication terminal 200 will be explained.

In step (step may be abbreviated as S) 102, the terminal related information acquisition unit 130 receives terminal position information from the communication terminal 200. In S104, the map selection unit 140 determines whether the position indicated by the terminal position information received by the terminal related information acquisition unit 130 in S102 is included in any of the plurality of range information stored in the map storage unit 112. By determining , it is determined whether the communication terminal 200 is located within the three-dimensional area 310 in which the 3D map is registered. If it is determined that it is located, the process advances to S106; if it is determined that it is not located, the process returns to S102.

In S106, the map selection unit 140 reads the 3D map corresponding to the current area of the communication terminal 200 from the map storage unit 112. In S108, the map selection unit 140 determines whether there is a 3D map to be additionally transmitted to the communication terminal 200. If there is an adjacent 3D map or destination 3D map to be transmitted to the communication terminal 200, the map selection unit 140 may determine that there is an additional map, and if there is no such map, it may determine that there is no additional map. If it is determined that there is an additional map, the process advances to S110.

In S110, the map selection unit 140 reads an additional 3D map from the map storage unit 112. In S112, the map transmitting unit 142 transmits the 3D map read in S106 and, if the 3D map has been read in S110, the 3D map in question to the communication terminal 200.
