Abstract

The present disclosure relates to a method, system and computer-readable recording medium for providing an electronic map-based service. According to an aspect of the disclosure, a method of recognizing a shape included in image data associated with an electronic map includes: acquiring region information corresponding to first image data; determining a candidate region on the electronic map using the region information; determining at least one candidate image using the candidate region; and recognizing a shape included in the first image data using the candidate image.

Claims

1. A method that uses a processor to provide image data associated with an electronic map, the method comprising:

acquiring region information corresponding to first image data based on the electronic map;

determining, by the processor, a candidate region on the electronic map based on the region information;

acquiring at least one of shape identification information based on the candidate region;

determining, by the processor, at least one of second image data based on the at least one of shape identification information; and

automatically generating an association relation between the first image data and the at least one of second image data, wherein the association relation comprises generating link information to link the first image data with the second image data, wherein icons representing the link information are displayed together with the first image data, and wherein the second image data linked to the first image data is provided in response to selection of one of the icons on the first image data.

2. The method of claim 1,

wherein the region information comprises coordinate information on the electronic map, and the candidate region comprises a region within a radius with reference to the coordinate information or a region within a polygon with reference to the coordinate information.

3. The method of claim 2, wherein the first image data is associated with information about a direction in which the first image data is captured.

4. The method of claim 2, wherein the candidate region comprises a region within an angle with reference to the direction in which the first image data is captured.

5. The method of claim 2, wherein the first image data comprises pixel columns, each of which is associated with direction information and wherein the candidate region on the electronic map is determined using the direction information of the pixel columns that comprise the shape of the first image data.

6. The method of claim 1, wherein the at least one of shape identification information comprises identification information of a geographical feature or an object included in the candidate region.

7. The method of claim 6, wherein the second image data is associated with a region on the electronic map where the geographical feature or object corresponding to the at least one of shape identification information is marked.

8. The method of claim 7, wherein determining at least one of second image data comprises:

calculating a degree of similarity between at least one of shapes included in the first image data; and

determining, as the second image data, at least one of image data whose degree of similarity is more than a predetermined value.

9. A system for providing image data associated with an electronic map, the system comprising:

a non-transitory storage device;

one or more units, executable by a processor, stored in the non-transitory device, comprising,

a candidate shape filtering unit configured to acquire region information corresponding to first image data based on the electronic map, configured to determine a candidate region on the electronic map based on the region information, and configured to acquire at least one of shape identification information based on a candidate region;

a shape recognition unit configured to determine at least one of second image data based on the at least one of shape identification information; and

an image association part configured to automatically generate an association relation between the first image data and the second image data, wherein the association relation comprises generating link information to link the first image data with the second image data, wherein icons representing the link information are displayed together with the first image data, and wherein the second image data linked to the first image data is provided in response to selection of one of the icons on the first image data.

10. The system of claim 9, wherein the region information comprises coordinate information on the electronic map, and the candidate region comprises a region within a radius with reference to the coordinate information or a region within a polygon with reference to the coordinate information.

11. A non-transitory computer-readable medium comprising an executable program which, when executed by a processor, performs the method of:

acquiring region information corresponding to first image data based on the electronic map;

determining, by the processor, a candidate region on the electronic map based on the region information;

acquiring at least one of shape identification information based on the candidate region;

determining, by the processor, at least one of second image data based on the at least one of shape identification information; and

automatically generating an association relation between the first image data and the at least one of second image data, wherein the association relation comprises generating link information to link the first image data with the second image data, wherein icons representing the link information are displayed together with the first image data, and wherein the second image data linked to the first image data is provided in response to selection of one of the icons on the first image data.

12. A method that uses a processor to capture image data associated with an electronic map, the method comprising:

receiving a search request, the request comprising image data associated with a region of the electronic map;

determining, by the processor, a candidate region corresponding to at least one candidate image data, the candidate region being defined and adjusted by using image data identification information comprising at least one of coordinate information, azimuth information and tag information, the coordinate information, the azimuth information and the tag information being provided for identifying the image data and being stored in a database; and

recognizing a shape image corresponding to the candidate image data of the candidate region by calculating a degree of similarity of the shape image of the candidate image data and a sample shape image based on the image data identification information.
