Abstract

Provided herein are an apparatus and a method for providing location information, which may determine the location of an object by identifying an overlaid area of the object in a virtual area divided into a plurality of areas when the object is recognized in a photographed image. The apparatus includes a camera configured to generate an image including a photographed object, an area extraction unit, executed by a processor, configured to extract divisional areas corresponding to the photographed object, among a plurality of divisional areas formed by dividing the image, and an output unit, executed by the processor, configured to output the extracted divisional areas.

output the extracted divisional areas.

2. The apparatus of claim 1, wherein the processor is further configured to extract the divisional areas on which the photographed object is overlaid by applying a virtual plate including a plurality of areas to the image.

3. The apparatus of claim 2, wherein the divisional areas are selected from at least one of a group consisting of:

horizontally divisional areas formed by dividing the virtual plate in a horizontal direction, vertically divisional areas formed by dividing the virtual plate in a vertical direction, and lattice divisional areas formed by dividing the virtual plate in horizontal and vertical directions.

4. The apparatus of claim 3, wherein sizes of the divisional areas are the same or vary according to the distance from one or more particular points included in the virtual plate.

5. The apparatus of claim 3, wherein the processor is further configured to generate the location information of the photographed object by referring to the extracted divisional areas,

wherein the location information of the photographed object includes at least one of a horizontal angle of the photographed object with respect to an imaginary reference line formed by aiming the camera unit, and a distance from the photographed object.

6. The apparatus of claim 5, wherein when the extracted divisional areas are horizontally divisional areas or lattice divisional areas, the processor is configured to determine the distance from the photographed object by referring to the divisional areas corresponding to a bottom end of the photographed object.

7. The apparatus of claim 1, wherein the processor is further configured to extract divisional areas corresponding to the photographed object by dividing the image into the plurality of divisional areas,

wherein the divisional areas are selecting from at least one of a group consisting of:

horizontally divisional areas formed by dividing the image in a horizontal direction, vertically divisional areas formed by dividing the image in a vertical direction, and lattice divisional areas formed by dividing the image in horizontal and vertical directions.

8. The apparatus of claim 7, wherein sizes of the divisional areas are the same or vary according to the distance from one or more particular points included in the image.

9. The apparatus of claim 7, wherein the processor is further configured to generate the location information of the photographed object by referring to the extracted divisional areas,

wherein the location information of the photographed object is selected from a at least one of a group consisting of:

a horizontal angle of the photographed object with respect to an imaginary reference line formed by aiming the camera toward the photographed object, and a distance from the photographed object.

10. The apparatus of claim 9, wherein when the extracted divisional areas are horizontally divisional areas or lattice divisional areas, the processor is further configured to determine the distance from the photographed object by referring to the divisional areas corresponding to a bottom end of the photographed object.

11. A method for providing location information, the method comprising:

generating an image including a photographed object using a camera;

extracting, by a processor, divisional areas corresponding to the photographed object, among a plurality of divisional areas formed by dividing the image; and

outputting, by the processor, the extracted divisional areas.

12. The method of claim 11, the extracting of the divisional areas further comprising extracting, by the processor, the divisional areas on which the photographed object is overlaid by applying a virtual plate including a plurality of areas to the image,

wherein the divisional areas are selected from at least one of a group consisting of:

horizontally divisional areas formed by dividing the virtual plate in a horizontal direction, vertically divisional areas formed by dividing the virtual plate in a vertical direction, and lattice divisional areas formed by dividing the virtual plate in horizontal and vertical directions.

13. The method of claim 12, wherein sizes of the divisional areas are the same or vary according to the distance from one or more particular points included in the virtual plate.

14. The method of claim 12, further comprising generating, by the processor, the location information of the photographed object by referring to the extracted divisional areas,

wherein the location information of the photographed object is selected from at least one of a group consisting of:

a horizontal angle of the photographed object with respect to an imaginary reference line formed by aiming the camera toward the photographed object, and a distance from the photographed object.

15. The method of claim 14, wherein when the extracted divisional areas are horizontally divisional areas or lattice divisional areas, the generating of the location information, by the processor, further comprises determining the distance from the photographed object by referring to the divisional areas corresponding to a bottom end of the photographed object.

16. The method of claim 11, wherein the extracting, by the processor, of the divisional areas further comprises extracting the divisional areas corresponding to the photographed object by dividing the image into the plurality of divisional areas,

wherein the divisional areas are selected from at least one of a group consisting of:

horizontally divisional areas formed by dividing the image in a horizontal direction, vertically divisional areas formed by dividing the image in a vertical direction, and lattice divisional areas formed by dividing the image in horizontal and vertical directions.
