Abstract

The invention relates to a three-dimensional scanning method, a three-dimensional scanning system and a computer readable storage medium. The three-dimensional scanning method comprises the followingsteps that a plurality of three-dimensional light surfaces are projected to the surface of a scanned object through a three-dimensional scanner, and two-dimensional images of the scanned object are synchronously acquired by using at least two cameras of the three-dimensional scanner to obtain at least two synchronous two-dimensional images; the tracker synchronously tracks the pose information ofthe three-dimensional scanner when the three-dimensional scanner collects at least two synchronous two-dimensional images; and the calculation unit generates credible three-dimensional point-surface information according to the spatial position relationship and the at least two synchronous two-dimensional images, and reconstructs a three-dimensional model of the scanned object according to the credible three-dimensional point-surface information and the pose information of the three-dimensional scanner corresponding to the credible three-dimensional point-surface information. According to themethod and the system, the problem that three-dimensional point-surface information mismatching is easily caused by the marking points on the surface of the scanned object in related technologies is solved, and errors caused by the marking points on the surface of the scanned object are avoided.

Description

technical field [0001] The present application relates to the field of three-dimensional scanning, in particular to a three-dimensional scanning method, a three-dimensional scanning system, a computer device and a computer-readable storage medium. Background technique [0002] The structured light 3D scanner is a device that uses the method of projecting structured light to obtain the 3D information of the measured object. It is currently widely used in industrial product inspection, reverse setting, simulation, positioning and other fields. The basic principle of structured light stereo vision is to use structured light (such as line laser, Gray code, Moiré fringe, etc.) The overall 3D model of the object is obtained by splicing and reconstructing point-surface information. In recent years, various types of structured light 3D scanning measurement equipment, especially hand-held 3D scanners, have developed rapidly. [0003] A handheld 3D scanner usually includes a structu...
