Abstract

In order to achieve 3D reconstruction of low-contrast and weakly textured ocean wave surfaces, a new stereo matching method for ocean wave images is proposed. Firstly, the binocular imaging system is calibrated, and the stereo image pair is subjected to epipolar correction; then, the corrected image is evenly divided into blocks, and the strongest Moravec feature points in the divided area are extracted; finally, the pyramid image matching strategy is used, combining the minimum the quadratic matching method obtains sub-pixel stereo matching results. Compared with the traditional Moravec feature matching method, the proposed method has higher matching accuracy and shorter matching time.
