The mismatching would happen in the region of no features such like the scene with smooth color distribution, or region of repeating patterns. Therefore 3D information might be wrong. According to our observation, most of these scenes are planar. Considering the above points, in this thesis, a method of stereo matching of planar scenes is proposed. First, the homography of each is obtained and then we use homograpy to segment each plane. After that, two images have to be rectified so that the corresponding search would change from 2D to 1D. Because the homography and region of plane has been obtained, the approximate position can be known by transforming point in view one to view two. The result would be shown in a dense disparity map.
