Regional information extraction method, region information output method and apparatus for the same
First Claim
1. A method of outputting regional information at a user device including an output unit and a camera module, the method comprising:
- taking a picture of a certain region on a globe by the camera module, wherein a plurality of lines representing a plurality of latitudes and a plurality of longitudes are printed on the globe;
selecting a part of the picture to provide a non-rectangular image, wherein boundary of the non-rectangular image is defined by two latitude lines and two longitude lines included in the picture;
deforming the non-rectangular image into a rectangular image, wherein the rectangular image is set as a regional image;
extracting a first regional image feature from the regional image;
extracting regional information on a geographical position which is represented by one regional image feature matching to the first regional image feature, wherein the one regional image feature is selected from a plurality of regional image features representing a plurality of regional images; and
outputting the regional information through the output unit,wherein the first regional image feature is expressed by a plurality of vectors, wherein each of the plurality of vectors is represented by [Equation 1],

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.

3. 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 first regional image feature from the regional image and extracting regional information on a geographical position which is represented by one regional image feature matching to the first regional image feature, wherein the one regional image feature is selected from a plurality of regional image 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, wherein, the regional image is a rectangular image obtained by deforming a non-rectangular image into the rectangular image, the non-rectangular image is a part of a picture of a certain region on a globe which is taken by a camera module installed on the user device, wherein a plurality of lines representing a plurality of latitudes and a plurality of longitudes are printed on the globe, boundary of the non-rectangular image is defined by two latitude lines and two longitude lines included in the picture, and the first regional image feature is expressed by a plurality of vectors, wherein each of the plurality of vectors is represented by [Equation 1]. - View Dependent Claims (4)
