STEREO VISION SYSTEM AND CONTROL METHOD THEREOF

摘要

PURPOSE: A stereo vision system and a control method thereof are provided to equalize brightness values of color information of right/left images inputted from right/left stereo cameras and obtain an image according to accurate depth information by compensating right/left images. CONSTITUTION: A stereo vision system comprises the following units. If an image of right/left stereo cameras is inputted, an image information extracting unit(200) extracts color information for adjusting brightness of an image. An image preprocessing unit(300) reduces noise of right/left images using the color information. A stereo matching unit(400) generates depth information by performing stereo matching on the right/left images through an algorithm. A matching result measuring unit(500) receives the depth information to measures a matching degree and changes a pre-stored calibration parameter.
