METHOD FOR MEASURING DISTANCE AND SYSTEM FOR STEREO MATCHING

摘要

PURPOSE: A distance measuring method and a stereo matching system is provided to enable a network mobile robot to easily obtain the distance information based on images without a separate stereo matching hardware or an additional distant sensor. CONSTITUTION: A distance measuring method comprises following steps. A reference motion vector is established by enabling calibration on first and the second cameras. A second camera images is encoded with reference to the first camera image. If blocks of the second camera images is predicted and encoded, the motion vector and the standard motion vector of the blocks are compared. If the compared motion vector is not the same as the standards motion vector, the size value of the motion vector is determined as disparity value.
