  In recent years, the spread of domestic mobile communications has improved remarkably, and it is evolving daily as a means of connecting people and things in various forms. This trend is expected to change not only people's lifestyle but also business, and the importance of mobile communications will increase in all social, economic and industrial scenes.

  Car navigation systems are also becoming increasingly popular in recent years, and various information search functions have recently been added. Major manufacturers and others are focusing on telematics (on-demand information services) that emphasizes linkage with mobile communications. The car navigation system is going to play a major role as its input / output device.

  Furthermore, due to the widespread use of car navigation and technological advancement of mobile communication terminals, there are signs of changes in the service targets from car navigation (car navigation) to navigation of people with mobile communication terminals such as mobile terminals (human navigation). For example, a service or the like that can display its own position information measured with a GPS-equipped mobile terminal on a two-dimensional map is also available.

  Among these information providing services using 2D maps, services that use 3D map information as a part of added value also appear, and various companies are working on their expression methods.

For example, in order to add value to the display information, the photographed images acquired by the imaging devices installed in a plurality of base stations are stored in the photographed image database in the server, and the mobile navigation device or server predicts the weather condition. A mobile navigation device that estimates a time for passing through each imaging point, acquires a real image from a server, and generates a three-dimensional image based on the real image acquired by the three-dimensional generation unit. (For example, refer to Patent Document 1).

<Navigation procedure 1>
FIG. 6 is a sequence chart showing the first embodiment of the navigation procedure in the present invention. FIG. 6 is a sequence chart for explaining an example of navigation processing for a building (structure) inquiry in response to an inquiry from a mobile communication terminal. In the process shown in FIG. 6, navigation is performed by the 3D map information server 15 and the 3D map attribute information server 16.

  First, when there is information on a building that the user wants to acquire, the mobile communication terminal 12 is directed to the building, and the mobile communication terminal 12 makes an inquiry to the 3D map information server 15 (S01). When making an inquiry from the mobile communication terminal 12, the item name (menu ID) when a specific item is selected from the menu items on the terminal screen or the position coordinates (Px) of the designated screen on the terminal screen. , Py). The state of processing on the terminal screen will be described later.

  In response to the inquiry instruction, the mobile communication terminal 12 uses the artificial satellite 14 to acquire the current position of the latitude, longitude, and height for the current position of the mobile communication terminal 12 (S02). In addition, as a method for acquiring position information, GPS, a PHS antenna, an altimeter, or the like can be used. Further, the position information may not be a combination of latitude, longitude, and height, and may be, for example, the national land 19 coordinate system.

  Next, the attitude information of the terminal is acquired (S03). The terminal posture information includes the front-rear direction and the left-right direction of inclination with respect to the horizontal plane, and the azimuth angle with respect to true north. Note that the orientation information acquisition method may be an azimuth meter, an inclinometer, a gyro sensor, or the like, and is used depending on the type and function of the mobile communication terminal 12.

  Next, the mobile communication terminal 12 transmits inquiry information (navigation request) to the three-dimensional map information server 15 via the communication network 13 (S04). At this time, the inquiry information to be transmitted is the current position information and the terminal attitude information acquired in S01 to S03 described above, and the model information for identifying the transmitted mobile communication terminal 12.

  The model information may be unique identification for each mobile communication terminal 12 or product identification of the terminal. More specifically, information related to the camera and display screen unique to each mobile communication terminal, lens distortion correction information, and the like may be included. With this model information, the 3D map information server 15 can acquire the angle of view information of the display screen provided in each model. Processing for the inquiry is performed from the angle of view information acquired from the model information of the mobile communication terminal, the current position information, and the attitude information of the terminal.

  The three-dimensional map information server 15 determines which user's position and user are based on the position and orientation of the mobile communication terminal 12 based on the position information, orientation information, and angle-of-view information obtained from the model information from the mobile communication terminal 12. A line-of-sight direction indicating whether the direction is facing is determined (S05).

  In S05, the position of the user in the three-dimensional map is first determined. This uses the latitude, longitude, and height information included in the position information transmitted from the mobile communication terminal 12 as they are. The line-of-sight direction is determined from the orientation information transmitted from the mobile communication terminal 12 based on the viewpoint tilt angle, viewpoint roll angle, and viewpoint pan angle, and the user's line-of-sight direction in the three-dimensional map.

  The 3D map information server 15 collates the building corresponding to the position and line-of-sight direction determined in S05 with the table stored in the 3D map information server 15 and identifies the building (S06). Here, the collation method will be specifically described. The position information is replaced with coordinates, and the intersection determination with the three-dimensional shape (polygon) on the extension line of the coordinate position in the three-dimensional map space is performed from the line-of-sight direction or the like. Then, the nearest three-dimensional shape is specified.

  The three-dimensional map information server 15 transmits the building information (building ID) specified in S06 to the three-dimensional map attribute information server 16 (S07). The 3D map attribute information server 16 acquires attribute information such as an attribute, a building name, or an address corresponding to the building ID sent from the 3D map information server 15 (S08), and outputs the attribute information to the 3D map information server 15 (S09).

  The 3D map information server 15 uses the attribute information acquired from the 3D map attribute information server 16 and the model information and attitude information from the mobile communication terminal 12 to display information to be displayed on the display screen in the mobile communication terminal 12. Select (S10). Next, display data for displaying the display information selected in S10 in correspondence with the display screen in the mobile communication terminal 12 is generated (S11). Specifically, the angle of view of the viewpoint specified from the model type is determined, and the visible range from the user is specified. Further, the display range is determined based on the angle of view information corresponding to the terminal model performance registered in advance. Further, the 3D map information server 15 converts the 3D position into 2D projection coordinates based on the viewpoint, converts them into display coordinates on the terminal screen, and calculates display coordinates on the terminal screen.

  Next, the three-dimensional map information server 15 transmits the calculated display coordinates on the terminal screen and inquiry result information to the mobile communication terminal 12 (S12). The mobile communication terminal 12 outputs the inquiry result information input from the 3D map information server 15 to the display screen based on the display coordinates (S13). In S13, when image information such as a building is captured on the display screen, an inquiry result is output to the display screen based on the display coordinates together with the image.

  Through the above-described steps S01 to S13, attribute information is added to the captured image and displayed on the screen. Therefore, highly accurate instruction information can be quickly displayed on the mobile communication terminal in response to the navigation request input from the mobile communication terminal. Thereby, accurate and highly accurate instruction information can be provided to the user.

  In addition, in the process (S06) for specifying the above-described building, when one building (structure) corresponding to the inquiry cannot be specified, a list of buildings at the position (direction) is created. This list is stored in the 3D map information server 15 and can also be output to the mobile communication terminal 12. As a result, more information can be provided to the user, and when further inquiries are made using this list, the processing of S05 has already been performed in the three-dimensional map information server 15, Since this process can be omitted, the inquiry result can be provided quickly.

<Navigation processing procedure 2>
Next, a navigation processing procedure in a route search inquiry from the mobile communication terminal 12 will be described using a sequence chart.

  FIG. 7 is a sequence chart showing a second embodiment of the navigation procedure in the present invention. FIG. 7 is a sequence chart when there is a request for route search and route guidance from the current location of the user to the destination location (destination) based on the destination location information input from the mobile communication terminal 12.

  In the process shown in FIG. 7, navigation is performed by the 3D map information server 15 and the 3D map attribute information server 16.

  First, the target position is input from the mobile communication terminal 12, and the mobile communication terminal 12 makes an inquiry to the 3D map information server 15 (S21). When making an inquiry from the mobile communication terminal 12, the inquiry is made by selecting a specific place name or place from a menu item on the terminal screen or by directly inputting it.

  In response to the inquiry instruction, the mobile communication terminal 12 acquires the current position including the latitude, longitude, and height using the artificial satellite 14 for the current position of the mobile communication terminal 12 (S22). The position information may not be a combination of latitude, longitude, and height, and may be, for example, the national land 19 coordinate system. Also, the mobile communication terminal 12 acquires terminal attitude information (S23).

  Next, the mobile communication terminal 12 transmits inquiry information (navigation request) to the three-dimensional map information server 15 via the communication network 13 (S24). At this time, the transmitted inquiry information is the target position information, current position information, and terminal attitude information acquired in S21 to S23 described above, and model information for identifying the transmitted mobile communication terminal 12. .

  The three-dimensional map information server 15 determines which user's position and user are based on the position and orientation of the mobile communication terminal 12 based on the position information, orientation information, and angle-of-view information obtained from the model information from the mobile communication terminal 12. A line-of-sight direction indicating whether the direction is facing is determined (S25). The specific processing content in S25 is the same as that in S05. Further, the 3D map information server 15 identifies a place from the destination position information sent from the mobile communication terminal 12, and the destination of the destination consisting of latitude, longitude, height, national land 19 system coordinates, etc. corresponding to the destination position. The position information is acquired (S26).

  Next, the 3D map information server 15 outputs the acquired current position information, target position information, and attitude information of the mobile communication terminal 12 to the route selection server 17 (S27).

  The route selection server 17 selects a route for the inquiry information including the current position information, the target position information, and the posture information from the 3D map information server 15 (S28), and the corresponding inquiry result information is displayed on the 3D map. The information is output to the information server 15 (S29). Here, as inquiry result information in route selection, inquiry result information corresponding to current position information, target position information, and posture information is stored in advance in the route selection server 17, and current position information, target position information, and posture are stored. The query result information accumulated based on the information is extracted and output. Further, the route selection server 17 has analysis means for analyzing the route from the current position and the latitude, longitude, height of the target position or the information of the national land 19 coordinate system, and the inquiry result information is obtained from the direction information of the analyzed route. Generate and output.

  The three-dimensional map information server 15 selects information to be displayed on the display screen in the mobile communication terminal 12 from the inquiry result information input from the route selection server 17 and the model information and posture information from the mobile communication terminal 12. (S30). Next, display data for displaying the display information selected in S30 in correspondence with the display screen in the mobile communication terminal 12 is generated (S31). Further, the 3D map information server 15 converts the 3D position into 2D projection coordinates based on the viewpoint, converts them into display coordinates on the terminal screen, and calculates display coordinates on the terminal screen.

  Next, the three-dimensional map information server 15 transmits the calculated display coordinates on the terminal screen and inquiry result information to the mobile communication terminal 12 (S32).

  The mobile communication terminal 12 outputs the inquiry result information input from the 3D map information server 15 to the display screen based on the display coordinates (S33). In S13, when image information such as a building is captured on the display screen, an inquiry result is output to the display screen based on the display coordinates together with the image.

  Here, the mobile communication terminal 12 determines whether it has arrived at the target position from the current position information (S34). If the destination position has not been reached (No in S34), the process returns to S22 and continues. If the destination has been reached (Yes in S34), the process is terminated. If the user cancels the route navigation inquiry before the user arrives at the destination during the processes of S21 to S34 described above, the navigation process ends at that point.

Through the above-described steps S21 to S34, route information and the like are displayed on the captured image on the screen, and navigation is performed. Therefore, it is possible to quickly display highly accurate information on the display screen in the mobile communication terminal in response to the navigation request input from the mobile communication terminal. Thereby, it is possible to provide accurate and highly accurate information to the user. Note that, in the above-described embodiment, not limited to the above, for example, the result of the user searching once is stored as history information, Thereafter, when there is a similar request from the same user or another user, the navigation information can be quickly displayed by displaying the history information.

  Further, the mobile communication terminal 12 is provided with an imaging device, and an image captured by the imaging device is transmitted to the 3D map information server 15. The 3D map information server 15 sends the image information and the image information to the server. By accumulating the registered registration date and time and the position information and posture information of the mobile communication terminal when the image was taken, when there is an inquiry corresponding to the accumulated image, the image is used as history information. The image regarding the building (structure) can be provided.

For example, when a certain user designates a target position with the mobile communication terminal 12, the three-dimensional map information server 15 generates a target position list indicating a two-dimensional map corresponding to the target position or a position and a viewpoint azimuth direction. The information is displayed on a display screen in the communication terminal 12. Next, when the user selects a viewpoint position from the map or list and sends the selection information to the 3D map information server 15, the 3D map information server 15 extracts an image of history information corresponding to the selection information. And displayed on the display screen in the mobile communication terminal 12.
Thereby, information can be provided quickly and with high accuracy in response to a user's inquiry.
