Stereo matching method, terminal and storage medium

Abstract

The invention discloses a stereo matching method, a terminal and a storage medium, and the method comprises the steps: sequentially selecting a pixel point in a reference image as a to-be-matched point, and calculating the gray average value of all neighborhood pixel points in a fixed window with the to-be-matched point as the center; respectively calculating a first bit string of the point to be matched and a second bit string of a first candidate matching point in a preset parallax search range in the comparison graph according to the gray average value; selecting a search strategy, calculating second bit strings of the remaining candidate matching points in the comparison graph, and respectively calculating matching cost values of the candidate matching points according to the first bit string and a plurality of second bit strings; selecting the minimum matching cost value, and taking the parallax of the candidate matching point corresponding to the minimum matching cost value as the optimal parallax of the point to be matched; and obtaining a parallax image according to the parallax of all the pixel points in the reference image. According to the invention, the resource consumption of the algorithm can be effectively reduced, and the algorithm can be deployed on a low-cost computing platform.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a stereo matching method, a terminal and a storage medium. Background technique [0002] Binocular cameras are increasingly used in smart home, industrial automation, security and other fields, mainly based on binocular stereo vision technology. The mechanism of binocular stereo vision technology to simulate the three-dimensional information of human eyes to recognize the scene is to use two cameras to obtain two two-dimensional images of the same scene from two angles, and then process the two-dimensional images to obtain the depth information of the original image and then obtain Three-dimensional stereoscopic image. [0003] In the processing of two-dimensional images by binocular stereo vision technology, the core is to achieve stereo matching. At present, the commonly used stereo matching method is as follows: take two two-dimensional images as the r...
