Aiming at the problem of holes and false contour in virtual view rendering technology, a new stereo matching algorithm is presented in this paper to obtain dense disparity map to complete the virtual view synthesis.Only two images are required for this method, which are segmented using mean shift algorithm.A good view of the disparity map and an effective interpolation method are basis for successful virtual viewpoint drawing.The weighted multi-window stereo matching method is used to obtain the initial disparity map, and the cross checking is employed to filter false match points and occlusion parts.The obtained dense disparity map is then view interpolated and noise filtered to finish the multiple point virtual view drawing.Experimental results with test images like Tsukuba provided by Middlebury dataset show that the algorithm effectively improves the quality of virtual view images.
