“Robust Stereo Matching with Surface Normal Prediction” by S. Zhang, W. Xie, G. Zhang, H. Bao, and M. Kaess. In Proc. IEEE Intl. Conf. on Robotics and Automation, ICRA, (Singapore), May 2017, pp. 2540-2547.
Traditional stereo matching approaches generally have problems in handling textureless regions, strong occlusions and reflective regions that do not satisfy a Lambertian surface assumption. In this paper, we propose to combine the predicted surface normal by deep learning to overcome these inherent difficulties in stereo matching. With the selected reliable disparities from stereo matching method and effective edge fusion strategy, we can faithfully convert the predicted surface normal map to a disparity map by solving a least squares system which maintains discontinuity on object boundaries and continuity on other regions. Then we refine the disparity map iteratively by bilateral filtering-based completion and edge feature refinement. Experimental results on the Middlebury dataset and our own captured stereo sequences demonstrate the effectiveness of the proposed approach.
