Abstract

The invention belongs to the technical field of image processing, and provides a binocular stereo matching method and apparatus based on oblique plane smoothing. The method includes: performing subsequent optimization on a semi-global stereo matching algorithm by employing an oblique plane smoothing algorithm; and segmenting an image by employing the thought of energy function minimization, classifying boundary points, and performing oblique plane smoothing on parallax fracture boundary points and shielding boundary points according to conditions. According to the binocular stereo matching method based on oblique plane smoothing, the phenomenon of parallax fracture can be solved, the final effect of a disparity map is smooth, and good smoothing effect can be achieved in shielding regions, low-texture regions, and depth discontinuous regions.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a binocular stereo matching method and device based on oblique plane smoothing. Background technique [0002] Binocular stereo vision is to simulate the human eyes, use two cameras to take left and right images from different angles, obtain the disparity map through the stereo matching algorithm, and restore the depth information in the scene according to the relationship between the disparity map and the depth map. [0003] Stereo matching algorithm is the focus of its research. At present, traditional stereo matching algorithms are mainly divided into three categories: local matching algorithms, global matching algorithms and semi-global matching algorithms. [0004] The local matching algorithm mainly performs matching by comparing the local characteristics within a certain range of the points to be matched. The advantage is that the calculation speed is fast, but t...
