Abstract

The invention is applicable to the field of image processing, and provides a structured light based three-dimensional image reconstruction method and device and a storage medium. The method comprisesthe steps of extracting main coding feature points of an inputted object coding image; constructing a topology network of the main coding feature points, and extracting all coding element images contained in the object coding image according to the topology network; locating the initial position of graphic feature points in each coding element image, and calculating auxiliary coding feature pointsof the coding element images; performing recognition on all coding element images by using a deep learning network according to the main coding feature points and the auxiliary coding feature points;matching recognized coding information corresponding to each coding element image with coding information corresponding to a prestored coding pattern according to a preset epipolar coding strategy soas to achieve decoding; and performing three-dimensional image reconstruction according to pre-obtained three-dimensional image reconstruction system calibration parameters and the matched decoding information so as to obtain a three-dimensional image of the object.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a three-dimensional image reconstruction method, device and storage medium based on structured light. Background technique [0002] The structured light 3D reconstruction system refers to projecting an optical pattern containing specific coded information onto the surface of an object, and then obtaining the correspondence through decoding to solve the matching problem in stereo vision, and then restore the 3D space coordinates at the projection point through the principle of optical triangulation . According to different projection patterns, structured light can be divided into point structured light, line structured light, multi-line structured light and surface structured light. Although the point structured light method, line structured light method and multi-line structured light method are relatively mature and simple, but Multiple images need to be ta...
