Abstract

The stereo matching image processing is studied by the characteristic area properties, the geometrical restrictions and color comparisons. The characteristic areas are the 4 directional connectivity areas bound by the edge parts. The geometrical restrictions are the size difference ratio between the characteristic areas, matching point displacement ratio between the centers of the gravity of the characteristic areas, the size distortion ratio between the added stereo matching pattern union and the reference stereo matching pattern. The proper stereo matching conditions are the state of the maximum and sufficient large pixel number on the overlap area, the satisfaction of the condition of the average row difference ratio on the overlap area, the similar state of the average color difference on the overlap area on the proper combinations of the characteristic areas. The ability of the studied stereo matching is experimented with respect to the colorful soccer ball object. The result of the stereo matching experiments provide the proper correspondence between the centers of the gravity of the characteristic areas. The geometrical restrictions is effective to select the good combination between the characteristic areas of the stereo matching patterns.
