Abstract

Provided are a regional information extraction method, a regional information output method, and an apparatus for the same. The regional information output method includes obtaining a regional image through the processing unit, transmitting the regional image to a server through the transmitting/receiving unit, receiving regional information on a geographical position that a regional image feature extracted from the regional image represents through the transmitting/receiving unit, and outputting the regional information through the output unit, wherein the geographical position represents one feature matching to the regional image feature, which is selected from a plurality of features representing a plurality of regional images.

Claims

1. A method of outputting regional information in a user device including a processing unit, a transmitting/receiving unit, and an output unit, the method comprising:

obtaining a regional image through the processing unit;

transmitting the regional image to a server through the transmitting/receiving unit;

receiving regional information on a geographical position that a regional image feature extracted from the regional image represents through the transmitting/receiving unit; and

outputting the regional information through the output unit,

wherein the geographical position represents one feature matching to the regional image feature, which is selected from a plurality of features representing a plurality of regional images.

2. The method according to claim 1, wherein the regional image feature is extracted by image-processing the regional image.

3. The method according to claim 1, wherein the regional image feature is calculated from difference values in light intensity between at least two pixels in the regional image.

4. The method according to claim 3, wherein each of the plurality of features is calculated from difference values in light intensity between at least two pixels in each of the plurality of regional images.

5. The method according to claim 1, wherein the regional image is obtained by deforming a non-rectangular image into a rectangular image, the non-rectangular image being defined by a couple of specific latitudes and a couple of specific longitudes of a globe where lines representing latitudes and longitudes are printed.

6. A regional information extraction server comprising:

a transmitting/receiving unit for receiving a regional image obtained by a user device; and

a processing unit for extracting a regional image feature from the regional image and extracting regional information on a geographical position that one feature matching to the regional image feature represents, which is selected from a plurality of features representing a plurality of regional images,

wherein the transmitting/receiving unit transmits the regional information to the user device to allow the regional information to be outputted through the user device.

7. The regional information extraction server according to claim 6, wherein the regional image feature is extracted by image-processing the regional image.

8. The regional information extraction server according to claim 6, wherein the regional image feature is calculated from difference values in light intensity between at least two pixels in the regional image.

9. The regional information extraction server according to claim 8, wherein each of the plurality of features is calculated from difference values in light intensity between at least two pixels in each of the plurality of regional images.

10. The regional information extraction server according to claim 6, wherein the regional image is obtained by deforming a non-rectangular image into a rectangular image, the non-rectangular image being defined by a couple of specific latitudes and a couple of specific longitudes of a globe where lines representing latitudes and longitudes are printed.

11. A regional information extraction server comprising:

a transmitting/receiving unit for receiving information on a regional image feature extracted from a regional image obtained by a user device; and

a processing unit for extracting regional information on a geographical position that one feature matching to the information, which is selected from a plurality of features representing a plurality of regional images,

wherein the transmitting/receiving unit transmits the regional information to the user device to allow the regional information to be outputted through the user device.

12. The regional information extraction server according to claim 11, wherein the regional image feature is extracted by image-processing the regional image.

13. The regional information extraction server according to claim 11, wherein the regional image feature is calculated from difference values in light intensity between at least two pixels in the regional image.

14. The regional information extraction server according to claim 13, wherein each of the plurality of features is calculated from difference values in light intensity between at least two pixels in each of the plurality of regional images.

15. The regional information extraction sever according to claim 11, wherein the regional image is obtained by deforming a non-rectangular image into a rectangular image, the non-rectangular image being defined by a specific latitude and longitude of a globe where lines representing latitudes and longitudes are printed.
