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:
- designating a building adjacent to be included in a specific building group if the adjacent building is next to a specific building in a building image inputted as a query and a distance between the adjacent building and the specific building is less than a certain distance;
matching the alignments of the buildings in the specific building group with those in a group of buildings included respectively in at least one panoramic image;
selecting a panoramic image that includes a certain group of buildings recognized to have the same or similar alignments to the buildings in the specific building group among the at least one panoramic image as the result of matching the alignments of the buildings;
matching a wall of the specific building with a wall of a building in the at least one panoramic image based on physical parameters of the wall by using a technology of matching a building'"'"'s shape or repeated pattern;
selecting a candidate panoramic image which includes a building recognized to have the same or similar wall to the specific building in the building image 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 in the building of the candidate panoramic image by using a technology of recognizing a string or a figure; and
determining a top panoramic image with a top 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.

9. A system for hierarchically matching a building image, comprising:
-
a building alignment matching part for designating a building adjacent to be included in a specific building group if the adjacent building is next to a specific building in a building image inputted as a query and a distance between the adjacent building and the specific building is less than a certain distance, matching the alignments of the buildings in the specific building group with those in a group of buildings included respectively in at least one panoramic image and selecting a panoramic image that includes a certain group of buildings recognized to have the same or similar alignments to the buildings in the specific building group among the at least one panoramic image as the result of matching the alignments of the buildings; a building wall matching part for matching a wall of the specific building with a wall of a building in at least one panoramic image based on physical parameters of the wall 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 building 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 panoramic image with the top degree of matching accuracy in the candidate panoramic image as the result of matching the local region. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
