Abstract

The invention provides a binocular stereo vision disparity map post-processing method and device, and the method comprises the following steps: generating a disparity map according to an obtained initial left and right image pair; generating a texture filtering template according to the initial left image / right image, and performing texture filtering on the disparity map according to the texture filtering template; carrying out speckle suppression on the filtered disparity map; carrying out hole filling on the disparity map subjected to the speckle suppression; and performing median filteringon the disparity map subjected to the hole filling. According to the method, post-processing of abnormal points in different types of disparity maps can be realized.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a binocular stereo vision disparity map post-processing method, a binocular stereo vision disparity map post-processing device, a computer device, a non-temporary computer-readable storage medium and A computer program product. Background technique [0002] Stereo matching is the most difficult and important step in the process of realizing binocular stereo vision technology. The current mainstream stereo matching algorithms include global stereo matching algorithm, semi-global stereo matching algorithm and local stereo matching algorithm. Among them, the local stereo matching algorithm has been widely used because of its high precision and low time consumption. The main steps of the local stereo matching algorithm include: cost calculation, cost aggregation, disparity calculation, and disparity map post-processing. [0003] Among them, due to the influence of ...
