  As shown in FIG. 1, the map server 50 includes a communication unit 52, a control unit 54, and a map database 56. The map database 56 stores map data. This map data stores a three-dimensional map. The three-dimensional map includes ground surface information, feature information, network information, and feature attribute information. The ground surface information is information representing the ground surface in a three-dimensional space. Specifically, the ground surface represents a shape including undulations of the ground, and is represented by using altitude data such as contour lines and data for distinguishing administrative divisions, roads, rivers, sea levels, and the like. The feature information is information such as the shape and height information of the feature, that is, information specifying the horizontal region of the feature (such as the latitude / longitude of the representative position and the planar shape of the feature), Information. Specifically, the information for specifying the horizontal region of the feature is, for example, latitude / longitude information of the constituent points of the polygon representing the horizontal shape of the feature. The information in the vertical direction is, for example, information indicating how many levels the feature is on the ground / underground, a map representing the floor of each floor, and the like. Further, as the information in the vertical direction, for example, it may be represented by a distance in the upward direction from the ground surface or a distance in the underground direction. The network information is information used for route search from the departure place to the destination, and includes information on the hierarchy moving means. The information on the hierarchy moving means is information indicating how the hierarchy moving means (steps, escalators, elevators, etc.) are in contact. Feature attribute information includes, for example, the type of feature (buildings, houses, public facilities, etc. where commercial facilities are located) and the location and type of facilities included in the features (Japanese food for restaurants, This information includes information related to the type of feature (such as Chinese food, Western food, etc.). Further, the attribute information of the feature may include information on whether or not to display the type of the feature included in the feature and the facility information on the appearance of the feature. Whether or not to display the appearance may be different depending on whether the target feature is represented by a two-dimensional model or a three-dimensional model. The control unit 54 includes a CPU, a ROM, a RAM, a hard disk, and the like, and executes a program for transmitting map data. The control unit 54 acquires map data corresponding to the request from the smartphone 20 from the map database 56 and transmits the map data to the smartphone 20 by executing this program. For this transmission, the communication unit 52 and the Internet INT are used.

  On the other hand, the smartphone 20 includes a main control unit 22, a communication unit 32, a communication control unit 34, a touch panel 36, a display unit 38, an audio output unit 40, and a GPS receiver 42.

This program is for realizing a search facility display process (described later together with FIG. 2) and the like. The communication unit 32 is a circuit for performing data communication or voice communication with the base station BS. The communication unit 32 operates to access the map server 50 via the base station BS and acquire map data. The communication control unit 34 is a circuit that performs incoming calls and calls for voice calls, conversion between voice signals and electrical signals, and the like. The smartphone 20 functions as a telephone by including the communication unit 32 and the communication control unit 34.

  The audio output unit 40 is a speaker that outputs audio. The GPS receiver 42 is a device for acquiring information indicating the current location of the smartphone 20 by receiving GPS signals transmitted from a GPS satellite and an indoor GPS transmitter. The current location is a position specified by the latitude / longitude and the hierarchical position. The hierarchical position is information indicating on which floor of the feature. The hierarchical position can be estimated based on GPS signals from GPS satellites and / or indoor GPS transmitters. The display unit 38 displays an image on the liquid crystal screen based on the control of the main control unit 22. The touch panel 36 acquires the position coordinates at which the user's finger, a dedicated pen, or the like touches the liquid crystal screen and inputs the position coordinates to the main control unit 22. The main control unit 22 determines a user instruction based on the input position coordinates, and executes processing corresponding to the determined instruction. The user instruction includes, for example, Internet search using a search engine.

Search facility display processing (FIG. 2):
FIG. 2 is a flowchart showing search facility display processing. The search facility display process is started based on the search condition input by the user. The search condition may be, for example, a Japanese restaurant located within a radius of 5 km from a specified point. Furthermore, as a search condition, it may be input that the position of a predetermined number (for example, 10) from the top among search facilities (facility that matches a search by a search engine) is indicated on a map. When the search facility display process is started, the main control unit 22 refers to the map data stored in the RAM 26, and uses the center point, scale, depression angle, azimuth angle, and viewpoint distance to vertically adjust the shape of the feature. A three-dimensional map in which a two-dimensional model expressing the height rising in the direction by approximating 0 is arranged on the ground surface in the three-dimensional space is displayed (step S61). The center point, scale, depression angle, azimuth angle, and viewpoint distance are based on user input or default settings are used. In the case of default, the center point and the scale are set so that the search facility to be displayed can be displayed. The depression angle may be 90 degrees (an angle looking down directly below), or may be an angle looking down obliquely by an angle smaller than 90 degrees. The value of the viewpoint distance may be finite or infinite.

  Subsequently, the main control unit 22 expresses this feature shape in the vertical direction based on the height information for the target feature (feature including the search facility) and the search feature (feature matching the search). The obtained three-dimensional model is displayed instead of the two-dimensional model (step S63). The main control unit 22 expresses other features excluding the target feature and the search feature by a two-dimensional model. To be precise, “display” is “performed on the liquid crystal screen based on the control of the main control unit 22” as described above, but here it is expressed as “performed by the main control unit 22”. To do. Next, the main control unit 22 displays the position of the search facility that appears in the appearance of the target feature (step S65). Whether or not the search facility appears in the appearance of the target feature is predetermined for each facility and is stored in the map database 56. In the present embodiment, when the search facility is located on a place other than the first floor, it is assumed that it does not appear on the exterior, and when located on the first floor, the outer periphery of the search facility and the outer periphery of the feature overlap at least partially. In some cases, the standard was to appear in the appearance, and not to appear in the appearance when the outer periphery of the search facility and the outer periphery of the feature did not overlap.

  FIG. 3 shows an example of a map displayed by the main control unit 22 (FIG. 3). FIG. 3A is a map in which the buildings 90, 91, 92, and 93 displayed in step S61 are represented by a two-dimensional model. Here, for example, if the user performs a character string search using “restaurant” as a keyword, the main control unit 22 refers to the map database 56, and if the searched facility includes information displayed on the exterior of the building, The facility is displayed on the exterior of the building. In the present embodiment, it is assumed that a Chinese restaurant is in the building 91 and a Japanese restaurant is in the building 92, and appears on the exterior of the building. It is assumed that the French restaurant and the Italian restaurant do not appear in the building 90. On the other hand, it is assumed that there is no restaurant in the building 93. As a result, as shown in FIG. 3B, the buildings 90, 91, and 92 represented by the three-dimensional model as the target feature in step S63 as a map in which the two-dimensional model and the three-dimensional model are combined, and 2 A building 93 that is still a dimensional model is displayed. Further, in step S65, the location of the Chinese restaurant is shown in the building 91 (A in FIG. 3), and the location of the Japanese restaurant is shown in the building 92 (B in FIG. 3).

  Next, the main control unit 22 visualizes and displays the inside of the target feature where the search facility does not appear on the exterior (step S67). In the case illustrated in FIG. 3, the building 90 corresponds. Subsequently, the main control unit 22 displays the position of the search facility included in the three-dimensional model that is the target feature visualized and displayed inside (step S69). Next, the main control unit 22 automatically deforms the display position of the hierarchy of the three-dimensional model whose interior is visualized so that the search facility is displayed (step S67). Specifically, the main control unit 22 moves the display position of the hierarchy of the three-dimensional model having the search facility to a position where the search facility that is invisible by overlapping with the upper hierarchy is displayed. Finish the search facility display process.

  FIG. 4 shows a building 90 that is a three-dimensional model whose interior is visualized by the main control unit 22. 4A shows a state before the display position of the hierarchy is moved by the main controller 22, and FIG. 4B shows a state after the display position of the hierarchy is moved. In the present embodiment, the main control unit 22 visualizes the inside of the three-dimensional model by making the outer wall and ceiling of the building transparent and displaying the outline with dotted lines, and displays a floor map of each floor. In the above-described step S69, as shown in FIG. 4A, the main control unit 22 uses the hierarchical structure inside the building 90 to search facilities (C (French restaurant), D (Italian restaurant) in FIG. 4). ) Cannot be indicated. In the step S71, as shown in FIG. 4B, the main control unit 22 displays the search facility in the building 90 by appropriately moving the display positions of the second and higher floors. The main control unit 22 sets the display position after moving the hierarchy of the three-dimensional model that can display the search facility, using the values of the depression angle and the viewpoint distance and the ground surface information. In the present embodiment, the main control unit 22 moves the display position of the hierarchy in the vertical direction so that the entire hierarchy including the search facility (in the case of FIG. 4, the first and second floors) is displayed. In addition, the vertical position of the layer is moved so that the height of the feature does not change as much as possible. Specifically, as shown in FIG. 4B, the main control unit 22 includes a hierarchy (3 to 6 floors) that does not include the search facility, and a hierarchy (4 to 7 floors) one level above the hierarchy. Reduce the distance.

  The dotted line portion connecting the first floor and the second floor and the dotted line portion connecting the second floor and the seventh floor in FIG. 4 indicate the hierarchy moving means (stairs, escalator, elevator, etc.). As shown in FIG. 4, the dotted line indicating the hierarchy moving means is deformed as the hierarchy position is moved. This modification is performed so as to maintain the connection relationship between the hierarchy and the hierarchy moving means. In the present embodiment, since the hierarchy moves in the vertical direction, the deformation of the dotted line means a translation in the vertical direction and / or a change in length.

  FIG. 5 shows a display when the search facility is located in the underground mall. In the case of the present embodiment, when the search facility is located in the underground mall, the map database 56 stores the search facility as not appearing in the appearance of the target feature. As shown in FIG. 5, the main control unit 22 refers to the map database 56, in order to display the underground shopping street with a three-dimensional model, the outer wall is made transparent and the positional relationship in the height direction where the facility is located is reversed. Above, the underground structure of the 3D model is moved above the ground surface and displayed. Specifically, the main control unit 22 moves the first basement level to the height of the first floor above the ground (ground level), further moves the second basement level to the height of the second floor above the ground, and the third basement level to the third floor above the ground level. It is displayed on the ground by reversing the positional relationship in the height direction. As a result, the position of the search facility (E in FIG. 5) located on the third basement floor is displayed by moving to the third floor above the ground.

effect:
According to this embodiment, even when the search facility is located inside the target feature and does not appear in the appearance of the target feature, the location of the facility is visualized by visualizing the inside of the three-dimensional model including the search facility. Can be displayed easily. Since such a display is also realized for a facility located in the basement, the facility located in the basement can be easily displayed. Moreover, by moving the first basement floor to the first floor above the ground and displaying it, the connection between the first basement floor and the first floor above the ground (positions such as stairs) can be displayed in an easy-to-understand manner, and the positional relationship in the height direction of the hierarchy By reversing, it is possible to display the connection relationship between the layers.

Correspondence between embodiment and application example:
Step S63 is the selection unit and expression unit, step S65 is the feature surface display unit, step S67 is the internal display unit, step S71 is the automatic model transformation unit, and the contents described with reference to FIG. 5 are the underground movement display unit. It corresponds to software for realizing each. The CPU 24 corresponds to hardware resources for realizing processing means, the RAM 26 for storage means, and the touch panel 36 for display means.

Other embodiments:
FIG. 6 shows another method for moving the display position of the hierarchy. In this method, the position of the three-dimensional model hierarchy is moved based on the user's input instead of the vertical automatic deformation of the map elements inside the three-dimensional model in step S71 in the search facility display process described above. is there. As shown in FIG. 6, the default display does not involve the movement of the hierarchy position. As a result, the positions of search facilities C and D are hidden. When the user flicks the building 90 in the direction of the arrow shown in FIG. 6 and receives an instruction input (deformation instruction input unit of the application example), the main control unit 22 determines that 3 The three-dimensional model is manually deformed, and the layers of the deformed three-dimensional model are connected by the information of the layer moving means (manual model deforming unit of the application example), and as shown in FIG. In order to display the map, the display position of the layer is moved while the ratio of the distance between the layers is not changed. Note that the display shown in FIG. 4B may be executed instead of the display shown in FIG.

  FIG. 7 shows a technique for moving a hierarchy in the horizontal direction as still another technique for moving the display position of the hierarchy of the three-dimensional model. As shown in FIG. 7, even when moving in the horizontal direction, the connection relationship of the hierarchy moving means is maintained and displayed. As shown in FIG. 7, in this method, the angle of the dotted line indicating the hierarchy moving means can also be changed. When this method is employed, it is conceivable to display a leftward arrow instead of the upward arrow shown in FIG. The method of moving in the horizontal direction is particularly effective in the case of three-dimensional display with a depression angle of 90 degrees and a finite viewpoint distance. Further, when moving in the horizontal direction, only the hierarchy where the search facility is located may be moved.

  In any of the methods shown in FIGS. 6 and 7, various kinds of inputs can be used to move the position of the hierarchy. For example, the main control unit 22 may not display an arrow. In this case, when a flick operation in an arbitrary direction is input, the main control unit 22 may move the position of the hierarchy in that direction. Alternatively, when the main control unit 22 has a predetermined direction of movement, does not display an arrow, taps the building 90, or inputs an instruction using the voice input function of the smartphone 20, the hierarchical position This movement may occur. In addition, the main control unit 22 may perform the movement of the hierarchical position in a spiral shape. That is, the position of each floor may be rotated by a predetermined angle around an axis (for example, the flow line of the escalator).

  FIG. 8 shows another method for the display when the search facility is located in the underground mall. As shown in FIG. 8, the main control unit 22 makes the hindering portion transparent in order to display the underground shopping street in a three-dimensional model while being located underground. Specifically, the main control unit refers to the map database 56 and makes the ground surface and other features displayed in the two-dimensional model transparent. In the case where the target feature (the feature displayed in the three-dimensional model) is obstructed, the main control unit 22 displays the higher ranking search order. That is, if the facility located in the underground shopping area is higher, the main control unit 22 makes the obstructing feature transparent. If it is the opposite, do not make the obstructing feature transparent. As shown in FIG. 8, the main control unit 22 moves the display position of the hierarchy downward in the vertical direction. As a result, the position of the search facility (E in FIG. 8) is displayed. This content corresponds to the underground display section of the application example.

In addition, the main control unit 22 adds a step of determining whether the scale is greater than or equal to the reference value before step S63, and displays the floor map display inside the feature displayed in the three-dimensional model, with the scale less than the reference value. In some cases, it may not be executed. This is because when the scale is less than the reference value and the feature is displayed small, even if such display is performed, it is not always easy to see. In addition, when the scale map is less than the reference value and the floor map display inside the feature is not executed, the scale is increased by the flick operation etc. for the feature. The floor map display may be executed by visualizing the inside of the object.
In order to display the inside of the feature, the main control unit 22 may make the outer wall and ceiling of the feature or feature semi-transparent instead of transparent.
The target features (features to be subjected to the three-dimensional display) include things other than buildings and underground malls. For example, when a specific seat in an indoor facility (such as a dome stadium or a designated seat in a theater) is a search facility, the indoor facility is a target feature.
The outline of the feature displayed in a transparent or translucent manner may or may not be displayed.
The main control unit 22 may move the position of the layer so that the ratio of the distance between layers does not change in step S71 of the search facility display process.
When the position of the search facility is hidden by the hierarchical structure, the main control unit 22 does not move the display position of the hierarchy, but makes at least a part of the other hierarchy that obstructs the display of the position of the search facility transparent or translucent. May be.
If the map displayed before the search facility display process is a two-dimensional display or a three-dimensional display with a depression angle of 90 degrees, the depression angle may be reduced in step S61.
When the map displayed before starting the search facility display process includes the feature displayed three-dimensionally, the main control unit 22 in the feature displayed three-dimensionally in the search facility display process. A thing that does not include a search facility may be changed to a two-dimensional display.
An internal map may also be displayed for features where the search facility appears on the exterior.
A feature that does not include a search facility may be displayed in three dimensions and an internal map may be displayed.

There are various methods for determining whether or not the search facility appears on the appearance of the feature. For example, unlike the previous embodiment, the map database 56 may not store whether the search facility appears in the appearance of the feature, and the main control unit 22 may determine each time. For example, the determination may be made according to the same criteria as in the previous embodiment. Alternatively, in addition to the reference, the determination may be made based on the depression angle and azimuth angle of the map and the ground surface. That is, for example, when a certain facility is located at the corner of the first floor of the feature, the facility is not visible by the outer wall of the feature when viewed from the diagonal of the corner. Moreover, it may become invisible depending on the height of the ground surface. In such a case, it may be determined that the appearance does not appear.
The main control unit 22 may not be a search facility as a facility whose position is to be displayed. For example, a place where the user has visited in the past and the number of times of the visit may be stored, and a place where the number of visits is large may be the target of position display.
The device to be incorporated may not be a smartphone. For example, various types such as a normal mobile phone, a tablet-type personal computer, a stationary personal computer (desktop type or notebook type), a car navigation device, and a head-mounted display are conceivable.

  The present invention is not limited to the above-described embodiments, examples, and modifications, and can be realized with various configurations without departing from the spirit of the present invention. For example, the technical features in the embodiments, examples, and modifications corresponding to the technical features in each form described in the summary section of the invention are to solve some or all of the above-described problems, or In order to achieve part or all of the above effects, replacement or combination can be performed as appropriate. Further, if the technical feature is not described as essential in the present specification, it can be deleted as appropriate.
