Embodiment Construction

[0089] Embodiments of the present invention provide a three-dimensional reconstruction method, device, device, and storage medium for Marker points, which acquire photographing information of Marker points photographed by several cameras to form a set of two-dimensional coordinate points, wherein the photographic information includes Marker points The two-dimensional pixel coordinates of the point; according to the preset matching error rate algorithm, the matching error rate between each two-dimensional coordinate point in the two-dimensional coordinate point set is calculated; according to the matching error rate, from the two-dimensional Selecting two-dimensional coordinate points whose matching error rate satisfies the preset condition in the coordinate point set is sequentially connected to generate a matching dendrogram of the two-dimensional coordinate point set; analyzing the length of each tree-like single chain in the matching dendrogram , and filter out the longest t...

Abstract

The invention relates to the technical field of image processing, and discloses a Marker point three-dimensional reconstruction method and device, equipment and a storage medium. The method comprisesthe following steps: acquiring shooting information in a plurality of cameras to form a two-dimensional coordinate point set; calculating a matching error rate between every two two-dimensional coordinate points in the two-dimensional coordinate point set; sequentially connecting the two-dimensional coordinate points in the two-dimensional coordinate point set to generate a matching tree diagram of the two-dimensional coordinate point set; screening out a tree-shaped single chain with the longest length in the matched tree diagram; on the basis of the tree-shaped single chain with the longestlength, matching branches with crossed two-dimensional coordinate points with the tree-shaped single chain with the longest length in the matching tree diagram, removing the two-dimensional coordinatepoints in the branches, and obtaining a maximum non-crossed tree-shaped group; and calculating a three-dimensional coordinate corresponding to the maximum non-crossed tree-shaped group. According tothe method, the maximum non-crossed tree clusters are extracted through epipolar error calculation, the matching degree of the 2D points is improved, and the accuracy of restoring the three-dimensional coordinates of the 2D points is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a three-dimensional reconstruction method, device, equipment and storage medium of Marker points. Background technique [0002] In the era of continuous development of Internet technology, with the continuous deepening of virtual reality technology to show its huge application prospects, many virtual reality technologies continue to emerge. Virtual reality technology is used in the public domain, Internet shopping, robot automation, remote communication, education, medical care and other fields, which puts forward extremely high requirements for the corresponding interaction accuracy. [0003] When capturing optical data, the shooting camera outputs a two-dimensional plane. In order to obtain three-dimensional three-dimensional data, it is necessary to obtain data from the same object at different angles at the same time through multiple shooting cameras. Then, ...
