System and method for providing additional information using image matching
First Claim
1. A system, comprising:
- an image input unit configured to receive one or more images;
a query image determination unit configured to determine a query image from the received one or more images;
a feature point extraction unit configured to extract one or more feature points from the query image, and to generate feature point information based on the one or more feature points;
a reference meta-information database configured to store at least a structure image identifier (ID) of a structure image of a structure on which an original image has been installed, structure image feature point information of the structure image, and additional information associated with the structure image ID;
an image matching unit configured to determine a matching structure image ID by comparing the feature point information with the structure image feature point information; and
an additional information provision unit configured to provide the additional information associated with the matching structure image ID.

Abstract
The present invention relates to a system and method for providing additional information using image matching. The present invention provides a system for providing additional information using image matching, including: a image input unit configured to receive a video or an image input from a user terminal; a query image determination unit configured to determine a query image, i.e., a query target, from the video or image received from the image input unit; a feature point extraction unit configured to extract feature points of the query image determined by the query image determination unit, and to generate feature point information of the extracted feature points; a reference meta-information database configured to store a structure image identifier (ID) of a structure image of a structure on which an original image has been installed, structure image feature point information of the structure image, and additional information to be provided to the user terminal in association with the structure image ID; an image matching unit configured to determine a matching structure image ID by comparing the feature point information of the query image generated by the feature point extraction unit with the structure image feature point information stored in the reference meta-information database; and an additional information provision unit configured to provide the additional information stored in association with the structure image ID determined by the image matching unit to the user terminal, and a method using the same.
