Hereinafter, a specific embodiment of a method and system for providing a function of moving from an aerial view to a distance view will be described.

It is a map service that provides a panoramic view of a street photo taken while driving with a camera installed in a vehicle. The aerial view is a map service that provides panoramic aerial photographs taken during a flight with a camera installed on an aircraft. In other words, the review and aerial view provide a 360 degree panoramic view of actual street or aerial photographs.

FIG. 3 shows an example of an aerial view, and FIG. 4 shows an example of a review.

As shown in FIGS. 3 and 4, the aerial view 300 is provided with a merrily review menu 301 for moving to the merrily review 400 so as to go down to the merrily review 400, In the review 400, an aerial view moving menu 401 for moving to the aerial view 300 is provided so that the aerial view 300 can be viewed and climbed.

As described above, the aerial view 300 and the rough review 400 are used as navigation means among each other by providing a moving function in association with each other.

As shown in FIG. 3, the aerial view 300 is characterized by a ground surface for a wide area, unlike the meridian 400. As described above, the function of moving from the aerial view 300 to the ground review 400 is provided. Because of the geographical review data taken in units of a certain distance (for example, 10 meters) There is a restriction on the radius that can be moved with respect to the center.

The present invention can expand the movable range by adjusting the density of the review data on the ground review area of the ground viewed in the aerial view.

FIG. 5 is a block diagram illustrating an example of components that a server of a server according to an exemplary embodiment of the present invention may include; FIG. 6 is a diagram illustrating an example of a method that a server can perform according to an exemplary embodiment of the present invention; Fig.

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

5, the processor 222 of the server 150 includes a data adjustment unit 510, a spatial search unit 520, and a view movement unit (not shown) 530). The components of processor 222 may optionally be included or excluded from processor 222 in accordance with an embodiment. In addition, in accordance with an embodiment, the components of the processor 222 may be separate or merged for the representation of the functionality of the processor 222.

The components of the processor 222 and the processor 222 may control the server 150 to perform the steps S610 through S640 that the view moving method of FIG. 6 includes. For example, the components of processor 222 and processor 222 may be implemented to execute instructions in accordance with the code of the operating system and the code of at least one program that memory 221 contains.

Herein, the components of processor 222 may be representations of different functions of processor 222 performed by processor 222 in accordance with instructions provided by the program code stored in server 150 . For example, the data adjuster 510 may be used as a functional representation of the processor 222 that controls the server 150 in accordance with the above-described instructions so that the server 150 adjusts the density of the review data.

In step S610, the processor 222 may read the necessary commands from the loaded memory 221 with instructions related to the control of the server 150. [ In this case, the read command may include instructions for controlling the processor 222 to execute steps S620 to S640 to be described later.

In step S620, the data adjustment unit 510 may adjust the density of the review node to a plurality of levels and refine it into separate data. In the case of a grand review, a distance photograph taken at a predetermined distance (for example, 10 meters) is provided as a 360 degree panorama view. At this time, the grand review node may refer to a point where a grand review is provided. For example, the data adjustment unit 510 may adjust the density by using a geohash algorithm for the review nodes photographed in units of a predetermined distance, and may preliminarily refine the data by using separate data. Geohacity is a hierarchical spatial data structure that divides a space into grid shapes as one of the space division methods. GeoHash has the property of being able to set the precision freely and to reduce the size by sequentially eliminating characters at the end of the code. For example, referring to FIG. 7, the data adjustment unit 510 applies a geomagnetism of 19 m precision, a geomagnetism of 76 m accuracy, and a geomagnetism of 610 m accuracy to a review node, You can refine your review data in separate tables by adjusting to three different levels.

Referring back to FIG. 6, in step S630, the spatial search unit 520 searches the center of the corresponding aerial view using the data refined in step S620 for the aerial view of the specific point, You can search for review nodes. At this time, when the map service is provided using the preliminarily refined data on the review data, it is possible to apply the LOD (level of detail) according to the search radius. The space searching unit 520 performs a spatial search on the polygon area according to the LOD with reference to the center of the aerial view based on the preliminarily refined data on the rough review data, and merges them to increase the data retrieval speed and reduce the data size .

In step S640, the view moving unit 530 may provide a function of moving from the aerial view to the distance view on the review node searched in step S630 for the aerial view of the specific point. In the present invention, the range of movement from the aerial view to the rough review can be enlarged by adjusting the density of the review nodes according to the distance, and the view moving unit 530 can adjust the density of the review nodes It is possible to provide a function of moving from a view to a distance view. The view moving unit 530 may provide a navigational review menu for moving to a review of each point on the reviewed review node through the LOD-based spatial search on the ground of the area shown in the aerial view.

As shown in FIG. 8, when the density of the grand review node is reflected without being adjusted, the moving radius 810 that can move to the grand review node based on the aviation view node is limited (for example, only 650 m ). Referring to FIG. 9, in the aerial view 300 that reflects the density of the review nodes as it is, movement to the distance view is possible only within a limited moving radius 810.

On the other hand, as shown in FIG. 10, by using the refined data obtained by adjusting the density of the rough review nodes, the LOD-based spatial search is performed according to the search radius, It is possible to enlarge the moving radius 1010 (e.g., 4000m) that can be moved to the review node. Referring to FIG. 11, the distance to the distance view can be enlarged to a moving radius 1010 without restriction of the distance to the ground review area seen in the aerial view 300.

According to the embodiments of the present invention, by adjusting the density of panoramic data according to the distance, it is possible to expand the range of moving from the aerial view to the rough review by reducing the data capacity and improve the speed.
