As shown in FIG. 1, the route guidance system 10 is configured by connecting an information processing apparatus 100 and a terminal apparatus 200 to each other via a network N.

  The network N is configured by a wireless network or a wired network. Examples of communication networks include mobile phone networks, PHS (Personal Handy-phone System) networks, wireless LAN (Local Area Network), 3G (3rd Generation), LTE (Long Term Evolution), 4G (4th GenerationMex), (Registered Trademark), infrared communication, Bluetooth (Registered Trademark), wired LAN, telephone line, power line network, IEEE 1394, and other networks.

  The terminal device 200 is a computer connected to the network N. Specifically, as the terminal device 200, for example, a mobile phone, a smartphone, a PC (Personal Computer), a PDA (Personal Digital Assistant), a tablet, a wearable terminal, a game machine, a car navigation device, and the like are assumed. However, it is not limited to these. For example, when simulating route guidance without moving, a terminal device such as a desktop PC having no portability may be used.

  The information processing apparatus 100 is a computer connected to the network N, and examples thereof include a PC and a server apparatus.

<2. Functional configuration>
<2-1. Functions of Terminal Device 200>
With reference to FIG. 2A, a functional configuration of the terminal device 200 according to the present embodiment will be described.
The terminal device 200 is an information processing device having a function of intermittently acquiring position information using, for example, a GPS (Global Positioning System) and transmitting the information to the information processing device 100 via the network N. As illustrated in FIG. 1, the terminal device 200 includes a main control unit 220 including a CPU and a memory, a storage unit 230 that stores various information, a communication unit 240 for connecting to a network N, a touch panel that receives an operation from a user, and the like. Input unit 210, a display unit 250 for displaying a screen, a positioning unit 260 for positioning current position information, and the like.

  It is desirable that a user installs a map application (hereinafter referred to as a map application) in the terminal device 200 to acquire map information from the information processing apparatus 100 and display a map or use a route guidance service. . The route guidance service is a service provided by the information processing apparatus 100 that searches a route from an arbitrary departure point to a destination for a user and provides information.

<2-2. Functions of Information Processing Device 100>
Next, a functional configuration of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. As illustrated in FIG. 2B, the information processing apparatus 100 includes, as functional units, for example, a map information DB 131, a guide information DB 132, a reception unit 101, a search unit 102, a layer creation unit 103, and a display control unit 104. Yes.

  The map information DB 131 stores content data on various maps such as vector data, raster data, and annotation (annotation) data for drawing a map in association with latitude and longitude information. The content data stored in the map information DB 131 includes, for example, roads, railways, rivers, mountains, commercial facilities, financial institutions, houses, signs, event information, store information, facility information, traffic regulation information, icons, and note information. And the like. In the map information DB 131, content data is stored in association with a layer corresponding to each attribute.

  Each layer preferably includes information such as the size and position of an area in which notes and content data are arranged. In the map information DB 131, for each layer, a priority order for display in the same layer and a priority order for different layers are registered together.

The priority order refers to an order in which display is prioritized when the display control unit 104 to be described later displays map information by overlapping layers. Specifically, when the coordinate position of the content is superimposed between different layers, the content included in the higher priority layer is displayed with priority over the content included in the lower priority layer. The Therefore, it is desirable that the display control unit 104 creates map information by drawing in order from the layer with the lowest priority. Also, for example, in the same layer, display with higher priority is given priority over content with lower priority.
The display control unit 104, which will be described later, combines a plurality of layers with coordinate axes and scales, etc., and overlays them based on the priority order associated with the layers, thereby providing map information relating to a single map including notes and road information. Can be created.

  Further, the map information DB 131 stores information related to the forced display layer. The compulsory display layer refers to a layer in which higher priority than other layers is set. For example, the forced display layer may include a plurality of layers. In this case, a predetermined range of priority is set for the forced display layer, and display is controlled by the display control unit 104 based on the priority in the forced display layer.

  FIG. 3 is a diagram schematically showing map information created by the display control unit 104 according to the present embodiment. Map information is comprised from the information regarding a some layer. In the example of FIG. 3, the map information includes, for example, a note layer L1 and a road layer L2. In the example of FIG. 3, the higher the priority is, the higher the layer located in the upper layer.

  For example, the note layer L1 is based on the character string information of each note (in the example of FIG. 3, “XX intersection”, “XX street”, etc.), information on the position (coordinates), size, etc. Created. Note that all portions of the note layer L1 other than the note are transparent. The road layer L2 is a layer in which an image indicating a road is drawn based on position information indicating a coordinate position through which the road passes.

In addition, the map information can include a plurality of layers according to the attribute of the content, such as a layer indicating a river image and a layer indicating a railway image, in the map information. Further, note information and road information do not need to be expressed in one layer, but can be expressed in a plurality of layers.
In the example of FIG. 3, the map information has a plurality of layers as the forced display layer A on the annotation layer L1.

  Note that the upper and lower layers in FIG. 3 indicate priority (drawing order), and the layers do not have to have an upper and lower order as a data structure. The display control unit 104 may output the plurality of layers included in the map information, and the terminal device 200 may perform the process of creating the map information by superimposing the layers.

  The guidance information DB 132 preferably stores road network data for performing route guidance for the user of the terminal device 200, for example.

  Road network data consists of road intersections, inflection points, end points, etc. as nodes, routes connecting each node as links, node data (node latitude and longitude), link data (link numbers), and all links The database includes link cost information data relating to cost information (distance and required time).

  Note that the information processing apparatus 100 preferably acquires road network data from an external management server and stores it in the guide information DB 132 in advance. However, the present invention is not limited to this, and the configuration may be such that every time a route search request is received from the terminal device 200, the road network data is referred to by querying an external management server.

  The receiving unit 101 receives an input of a destination from the user. For example, the reception unit 101 receives a route search request from the terminal device 200 in which the map application is installed. Specifically, the positioning unit 260 of the terminal device 200 can transmit the measured latitude and longitude of the current position to the receiving unit 101 as the latitude and longitude of the departure place. In addition, for example, the user may operate the terminal device 200 to select a departure point and a destination from the points displayed on the map, and transmit them to the reception unit 101. In addition, the receiving unit 101 can further receive an input of a waypoint through which the user arrives at the destination.

  The search unit 102 searches for a route to the destination based on the set cost information when the receiving unit 101 receives an input of a departure place and a destination. For example, the search unit 102 searches for a route from the departure point to the destination by referring to the road network data in the guidance information DB 132 according to the latitude and longitude of the departure point and the destination transmitted from the terminal device 200. At this time, the optimum route can be searched by sequentially searching for a link from the departure node to the destination node, and following the link having the smallest link cost information as a guide route. As such a route search method, a known method such as a label determination method or a Dijkstra method can be used. The “optimum” route means that the cost information from the departure place to the destination is the smallest.

  The layer creation unit 103 creates a guidance layer having information on the route to the destination in the forced display layer. For example, the layer creation unit 103 can set the priority order corresponding to the forced display layer as the guidance layer. The information on the route is, for example, content data such as the note information on the destination, the building polygon, and the note information on the intersection name at the corner.

  In addition, it is desirable that the layer creation unit 103 creates the guidance layer so as to have information regarding the waypoints. When creating the guidance layer, the layer creation unit 103 desirably determines the display priority within the guidance layer. For example, the layer creation unit 103 stores the priority order of each content in the guide layer in the map information DB 131 so that the note information about the destination has the highest priority and the information about the building polygon about the waypoint has the lowest priority. Can be determined. The priority order of each content may be registered in advance in the map information DB 131, or the layer creation unit 103 may determine when creating the guidance layer.

  Furthermore, when there is a layer corresponding to the attribute of the target, the layer creating unit 103 can move the layer corresponding to the attribute of the target to the forced display layer. For example, when a convenience store is used as a route guidance target, the layer creation unit 103 refers to the map information DB 131 and confirms whether a layer (convenience store layer) corresponding to the content related to the convenience store is stored. When the convenience store layer is registered in the map information DB 131, the layer creation unit 103 moves the convenience store layer to the forced display layer. Specifically, the layer creation unit 103 changes the priority order of the convenience store layers in the order of priority corresponding to the forced display layer. It is desirable that the layer creating unit 103 sets a priority order lower than that of the guidance layer for the target layer among the priority orders corresponding to the forced display layer.

  Although it is desirable that the administrator of the information processing apparatus 100 sets the attribute to be the target in advance, the attribute is not limited to this, and when the user of the terminal apparatus 200 transmits a route guidance request to the information processing apparatus 100 May be specified.

  The display control unit 104 controls display of the map using a plurality of layers created according to the attributes of the content to be drawn on the map. Each of the plurality of layers created according to the attribute of the content to be drawn on the map has information regarding the corresponding content. For example, the display control unit 104 creates map information by overlaying layers stored in the map information DB 131 with coordinate axes aligned. In addition, when the receiving unit 101 receives an input of a destination, the display control unit 104 prioritizes information included in a layer included in the forced display layer over information included in other layers not included in the forced display layer. To display.

  The display control unit 104 performs overlap determination between different layers and within the same layer, and controls display. For example, in the case of different layers, when content overlaps at the same coordinate position, the display control unit 104 performs control so that the content included in the layer positioned above is displayed with priority. In addition, when the drawing areas overlap in the same layer, the display control unit 104 determines the content to be displayed based on the priority order in the layer.

  Note that the display control unit 104 may be configured to determine whether or not the control using the forced display layer is possible according to the scale at the time of route guidance. Specifically, when the scale of the displayed map information is large, the display control unit 104 does not use the compulsory display layer, and does not use the forced display layer, but the layer corresponding to the attribute of the guidance layer or the target object in the priority order according to the design. May be drawn.

<3. Processing flow>
A map display process flow of the information processing apparatus 100 according to the present embodiment will be described with reference to FIG. Each processing step included in the processing flow described below can be executed in any order or in parallel as long as there is no contradiction in the processing contents. These steps may be added. Further, a step described as one step for convenience can be executed by being divided into a plurality of steps, while a step described as being divided into a plurality of steps for convenience can be grasped as one step.

  When the user operates the terminal device 200 to activate the map application, the user selects a departure point, a destination, and a waypoint. This selection may be performed by inputting a latitude / longitude or an address, or by selecting a point that the user wants to display from a map. Further, the terminal device 200 may automatically set the current position as the departure place. When the user selects a departure point, a destination, and a waypoint, the terminal device 200 transmits these latitude and longitude to the reception unit 101.

  When the accepting unit 101 accepts the latitude and longitude of the departure point, the destination, and the waypoint transmitted from the terminal device 200 (S101: YES), the searching unit 102 refers to the road network data and accepts the accepting unit. A route is searched based on the latitude and longitude from the departure point to the destination received by 101 and the latitude and longitude of the waypoint (S102).

  The layer creation unit 103 creates a guidance layer having content data relating to the destination and waypoints in the forced display layer (S103). Further, the layer creation unit 103 moves the layer corresponding to the attribute of the target to the forced display layer (S104).

  The display control unit 104 controls the display so that the layers included in the forced display layer are displayed with priority over other layers not included in the forced display layer (S105).

  On the other hand, when the receiving unit 101 does not receive an input (S101: NO), the display control unit 104 controls the display so that the layer positioned above is displayed with priority (S106).

  As described above, the layer creation unit 103 of the information processing apparatus 100 according to the present embodiment creates a guidance layer having content data related to the destination and waypoints in the forced display layer. In addition, the layer creation unit 103 moves the layer corresponding to the attribute of the target to the forced display layer. Then, the display control unit 104 controls the display so that the layer included in the forced display layer is displayed with priority over other layers not included in the forced display layer. For this reason, the information processing apparatus 100 according to the present embodiment can continue to display the information about the destination and the target included in the forced display layer regardless of the display position and scale of the map.
