Abstract
To provide an image matching method, an image matching apparatus, and a program able to perform a matching images at a high accuracy. A Hough transform unitperforms a Hough transform processing to a registered image AIM and an image to be matched RIM, in detail, an image processing by which points in each image are transformed to a curved pattern and linear components in each image are transformed to a plurality of the overlapped curved-patterns, based on a distance ρ from a reference position to a shortest point in a straight line L passing through a point in the image and an angle θ between a straight line npassing though the reference position and the shortest point and a x-axis as a reference axis including the reference position, and generating a transformed image Sand a transformed image S. A judgment unitperforms a matching of the registered image AIM and the image to be matched RIM based on a degree of an overlap of the patterns in the transformed image Sand the transformed image Sand a matching or mismatching of the patterns in the same.
