SYSTEM FOR REAL-TIME STEREO MATCHING CAPABLE OF INCREASING A MATCHING RATE AND MINIMIZING MATCHING ERRORS BY NOT MEASURING THE CORRELATIVITY OF AN UNNECESSARY AREA

摘要

PURPOSE: A system for real-time stereo matching is provided to improve stereo matching speed and a matching rate by gradually optimizing a disparity range for stereo matching using a stereo matching result of a previous frame image and thus reducing unnecessary computations for matching.;CONSTITUTION: A system for stereo matching comprises a depth map generator(100), a disparity range controller(200), and a stereo matching unit(300). The depth map generator generates depth map information based on a stereo matching result of an N-frame image. The disparity range controller generates disparity range information using the depth map information. The stereo matching unit performs stereo matching computations of an N+1-frame image using the disparity range information.;COPYRIGHT KIPO 2013;[Reference numerals] (100) Depth map generator; (200) Disparity range controller; (210) Standard displacement setting unit; (215) Initial standard displacement range storing unit; (220) Offset displacement setting unit; (225) Initial offset displacement range storing unit; (230) Depth map reliability determining unit; (240) First MUX unit; (245) First MUX unit; (300) Stereo matching unit
