Abstract: The current widely used matching costs are sensitive to complex optical distortions, such as vignetting. By analyzing the camera model,the robustness of the curvature-based matching cost against the vignetting effect is proved. Then,the integral image is used to compute the curvature-based matching cost so that the speed of the algorithm is improved significantly. Finally,a regularization term is designed based on curvature constraint,and thus the over-smoothing of the disparity map is avoided by restricting the belief propagation in the depth discontinuity area. Experimental results verify the effectiveness of the proposed method.
