A Stereo-Matching Method Using Multiresolution Images
Yoshikatsu Kimura · 2001
To solve problems related to the conventional method, we propose a stereo-matching method using multiresolution images, which 1) carries out stereomatching from low to high resolution in the coarse-tofine search mode; and 2) produces short-distance images with low resolution and long-distance images with high resolution (Fig. 1). 3. Experiment We made a comparative evaluation of the reliability and computation volume of distance images using both the conventional and proposed methods. The distance images were compared with the correct disparity rate for each sampling ratio (ratio of distance images, extracted from the reliability evaluation of respective methods, to the total images). Judgment of the correct/error value of the distance was made in comparison with the visually collated values. The computation volume was determined by comparing the processing time for installing the software.
