Hereinafter, a specific embodiment of a method and system for providing a movement function through an aerial view will be described.

Aerial view is a map service that provides aerial photographs taken in flight with a camera installed in an aircraft in the form of a panorama, and you can view a single point 360 degrees like street view. Street View is a map service that provides a panoramic view of street photos taken while driving with a camera installed on a vehicle, etc. You can rotate a photo 360 degrees to view a point from various directions. In other words, the street view and the aerial view provide an actual street or aerial view in a 360-degree panoramic view.

In the case of the distance view, the nodes are connected to each other by closely photographing them at regular distances (for example, 10 m), but the aerial view is difficult to move freely and naturally by using the aerial view.

In the present invention, it is possible to provide a map service capable of moving through the aerial view by connecting all the aerial view nodes nationwide with one network.

3 is a block diagram showing an example of a component that a processor of a server may include according to an embodiment of the present invention, and FIG. 4 is an example of a method that the server can perform according to an embodiment of the present invention It is a flow chart showing.

The server 150 according to the present exemplary embodiment serves as a platform for providing a map service to a plurality of electronic devices 110, 120, 130, and 140 that are clients. The server 150 may provide a map service in conjunction with a browser installed and driven on the electronic devices 110, 120, 130, 140 or a dedicated application installed on the electronic device 110.

The processor 222 of the server 150 is a component for performing the map moving method according to FIG. 4, and may include a network configuration unit 310 and a map provision unit 320 as illustrated in FIG. 3. have. Depending on the embodiment, components of the processor 222 may be selectively included or excluded from the processor 222. Further, according to an embodiment, the components of the processor 222 may be separated or merged to express the function of the processor 222.

The processor 222 and the components of the processor 222 may control the server 150 to perform steps S410 to S430 included in the map moving method of FIG. 4. For example, the processor 222 and components of the processor 222 may be implemented to execute instructions according to code of an operating system included in the memory 221 and code of at least one program.

Here, the components of the processor 222 may be expressions of different functions of the processor 222 performed by the processor 222 according to instructions provided by program code stored in the server 150. . For example, the network constructing unit 310 may be used as a functional expression of the processor 222 that controls the server 150 according to the above-described command so that the server 150 constructs a relation network for the aerial view.

In step S410, the processor 222 may read a required command from the memory 221 loaded with commands related to the control of the server 150. In this case, the read command may include an instruction for controlling the processor 222 to execute steps S420 to S430 to be described later.

In step S420, the network configuration unit 310 may configure a network representing a relation between the aerial view nodes, that is, an aerial view relation network, by connecting the aerial view nodes of all regions providing the map service to one network. The aerial view node may mean a point at which the aerial view is provided, for example, a photographing point of the aerial view. In other words, the network configuration unit 310 may configure the relation network by connecting aerial view nodes scattered in all regions to each other. At this time, the network configuration unit 310 may configure a relation network for an aerial view node using a triangulation technique, for example, a Delaunay triangulation technique. In detail, the network configuration unit 310 may configure a relation network in both directions of an edge acquired by triangulation after applying triangulation using each aerial view node as a vertex. In order to provide a mobility function using an aerial view in a map service, directionality, that is, network expansion is required, and the network configuration unit 310 may generate and connect an aerial view node using Delaunay triangulation.

In step S430, the map providing unit 320 may provide a movement function through the aerial view using the aerial view relation network configured in step S420, and at this time, a map service that can be moved through the aerial view without disconnection between nodes. Can provide. The map providing unit 320 may provide a more free and natural movement function for all regions without disconnection using an aerial view in which nodes are connected by one network. In the case of the area where the aerial view node is dense, data management becomes difficult due to many relations. By using the Delaunay triangulation technique, the characteristics and advantages of the technique can lighten the relation data of the network and the connection between nodes is relatively straightened. The shortest path movement function can be realized. Also, the map providing unit 320 may provide a movement function for a route personalized by the user of the electronic device 110. For example, the map providing unit 320 may connect the location photographed by the spot to a single network to create a personalized route and provide a mobile map in response to the route. For example, the map providing unit 320 may provide a function for re-viewing the travel route using the user's travel photos. As another example, the map providing unit 320 may generate an aerial view node selected by the user as a personalized route, and it is also possible to provide a mobile map through a relation of the generated personalized route.

In the aerial view 800, the aerial view UI 801 for providing the aerial view can be displayed at each point that provides the aerial view within the area currently visible in the aerial view 800. To view the aerial view of another point, the user selects the aerial view UI 701 of the corresponding point on the general map screen 700 or the current aerial view 800 if the point is visible from the currently used aerial view 800. ), the aerial view UI 801 of the corresponding point may be selected.

In the existing map service, since the surrounding aerial view node is simply searched by radius search, disconnection with a distant node occurs, and above all, the aerial view node does not use the aerial view UI 801 because the aerial view nodes are not connected to each other Is unable to move to another node.

9 to 10 show an example of a map screen that can be moved without disconnection between aerial view nodes in one embodiment of the present invention.

Referring to FIG. 9, the network configuration unit 310 may configure an aerial view relation network by connecting each aerial view node 901 on the map 900 and applying a triangulation that divides a plane into triangles. When the user selects a UI of a specific aerial view node on the general map screen 900, the map providing unit 320 may provide the aerial view 1000 of the corresponding point, as shown in FIG. At this time, the map providing unit 320 may provide a movement function through the aerial view using the aerial view relation network. For example, the map providing unit 320 may provide a mobile UI 1003 for a mobile transition between aerial view nodes on the screen of the aerial view 1000 based on the aerial view relation network. The map providing unit 320 may move to another adjacent aerial view node according to the aerial view relation network or to an aerial view node at a remote location in response to manipulation of the moving UI 1003 on the screen of the aerial view 1000. have. The function of moving the aerial view not only turns one point 360 degrees, but also allows all aerial view nodes in all regions to be connected to one network to move directly to another region from the aerial view and view the aerial view of the moved region. have.
