Abstract

The invention relates to a multi-line laser point pair determination method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first laser line set in a first laser diagram and a second laser line set in a second laser diagram; the first laser line set comprises at least one first laser line, and the second laser line set comprises at least one second laser line; the first laser diagram and the second laser diagram are obtained by shooting the same scene; a first laser point set located on the first laser line is obtained, and a second laser point set located on the second laser line is obtained; according to a laser transformation relation set, performing multiple uniqueness judgment on the first laser point set and the second laser point set to obtain a target point pair; and constructing according to the target point pair to obtain a three-dimensional point cloud. By adopting the method, the accuracy of point pairs can be improved.

Description

technical field [0001] The present invention relates to the technical field of laser scanning, in particular to a multi-line laser point pair determination method, device, computer equipment and computer-readable storage medium. Background technique [0002] In laser real-time 3D scanning, the determination of laser corresponding points is very important. The traditional multi-line laser point pair determination method is to extract the left and right feature points of the laser image, and obtain the matching point pairs by means of feature point matching. In the point pair determination of traditional multi-line laser, there is the problem of point pair inaccuracy. Contents of the invention [0003] Based on this, it is necessary to provide a multi-line laser point pair determination method, device, computer equipment and storage medium for the above technical problems. [0004] A method for determining a point pair of a multi-line laser, the method comprising: [0005...
