ABSTRACT:
This invention provides a method of extracting corresponding points from plural images with improved reliability and with a shortened process time. In the method of this invention, the extraction of the corresponding points in plural images is achieved by determining the right-side epipolar line, on which the corresponding points should be positioned, by calculation, and transferring candidate corresponding points, obtained on the right-side image by a conventional method for extracting the corresponding points, onto the points of shortest distance on thus determined right-side epipolar line.
