摘要
Providedis a method for estimating a disparity search range to which multi-level disparity image partition is applied, and a stereo image matching device using the same in that a disparity histogram of a previous disparity image is analyzed at the time of stereo matching of a continuous image, the disparity image is divided into various sizes of image blocks, and a disparity search range is estimated on the basis of a disparity value having the number of pixels equal to or more than a predetermined threshold value for each image block, thereby decreasing a calculation amount while improving a stereo matching rate of the next frame.
