Abstract
An image matching method capable of matching images with a high precision and a program and an image matching system for the same, providing a conversion unit for performing image processing based on a registered image and a match image for converting points in each image to patterns of curves based on a distance from a reference position to the closest point on a straight line passing through each point in the image from the reference position and an angle formed by a straight line passing through the reference position and the closest point and an x-axis as a reference axis including the reference position, converting linear components in the images to patterns of a plurality of overlapped curves, and generating converted images, a correlation value generation unit for performing correlation processing based on the converted images and generating a correlation value, and a matching unit for performing the matching based on a signal indicating the correlation value generated by the correlation value generation unit.
