|1. (WO2018098891) STEREO MATCHING METHOD AND SYSTEM|
|Applicants:||CHENGDU TOPPLUS VISION TECHNOLOGY CO., LTD.
|Title:||STEREO MATCHING METHOD AND SYSTEM|
A stereo matching method and system. The method comprises: extracting feature points of left and right images and performing feature point matching on the feature points to determine support points (S100); constructing a Delaunay triangle according to the support points, the Delaunay triangle comprising prior probabilities of all pixel point parallaxes within the triangle, and the minimum support distances between pixel points and the support points (S110); calculating parallax conditional probabilities and parallax confidence levels of pixel points in the left image using a parallax calculation method (S120); and calculating, according to the Delaunay triangle, the parallax conditional probabilities, and the parallax confidence levels, an optimal posterior parallax using a Bayesian method (S130). The method implements rapid matching to obtain a high precision parallax image, and is particularly suitable for a mobile platform or application fields having high requirements on real-timeliness.
