METHOD AND SYSTEM FOR HIERARCHICALLY MATCHING IMAGES OF BUILDINGS, AND COMPUTER-READABLE RECORDING MEDIUM
First Claim
1. A method for hierarchically matching a building image, comprising the steps of:
- (a) matching a wall of a specific building in the building image inputted as a query with a wall of a building in at least one panoramic image by using a technology of matching a building'"'"'s shape or repeated pattern;
(b) selecting a candidate panoramic image which includes a building recognized to have the same or similar wall to the specific building in the panoramic image as a result of matching its wall with others;
(c) matching at least one local region, if containing a recognizable string or figure, in the specific building with local region in the building of the candidate panoramic image by using a technology of recognizing a string or a figure; and
(d) determining a top n panoramic image with a top n degree of matching accuracy in the candidate panoramic image as the result of matching the local region.

Abstract
The present invention relates to a method for hierarchically matching a building image. The method includes the steps of: matching a wall of a specific building in the building image inputted as a query with a wall(s) of a building(s) in at least one panoramic image by using a technology of matching a building'"'"'s shape or repeated pattern; selecting a candidate panoramic image(s) which includes a building(s) recognized to have the same or similar wall to the specific building in the panoramic image(s) as a result of matching its wall with others; matching at least one local region, if containing a recognizable string or figure, in the specific building with local region(s) in the building(s) of the candidate panoramic image(s) by using a technology of recognizing a string or a figure; and determining top n panoramic image(s) as the result of matching the local region.

10. A system for hierarchically matching a building image, comprising:
-
a building wall matching part for matching a wall of a specific building in the building image inputted as a query with a wall of a building in at least one panoramic image by using a technology of matching a building'"'"'s shape or repeated pattern and selecting a candidate panoramic image which includes a building recognized to have the same or similar wall to the specific building in the panoramic image as a result of matching its walls with others; a local region matching part for matching at least one local region, if containing a recognizable string or figure, in the specific building with the local region in the building of the candidate panoramic image by using a technology of recognizing a string or a figure; and a matching result providing part for determining top n panoramic image with the top n degree of matching accuracy in the candidate panoramic image as the result of matching the local region. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
