STRUCTURED LIGHT-BASED THREE-DIMENSIONAL IMAGE RECONSTRUCTION METHOD AND DEVICE, AND STORAGE MEDIUM

摘要

A structured light-based three-dimensional image reconstruction method and device, and a storage medium, applicable to the field of image processing. The method comprises: extracting main encoding feature points of an input object encoding image; constructing a topological network of the main encoding feature points, and extracting all encoding element images comprised in the object encoding image according to the topological network; positioning the initial position of a graphical feature point in each of the encoding element images, and calculating an auxiliary encoding feature point of the encoding element image; identifying all encoding element images by means of a deep learning network according to the main encoding feature points and the auxiliary encoding feature points; matching encoding information corresponding to each of the identified encoding element images with encoding information corresponding to a pre-stored encoding pattern according to a preset polar line encoding policy to implement decoding; and performing three-dimensional image reconstruction on the object according to pre-acquired calibration parameters of a three-dimensional image reconstruction system and decoding information obtained by the matching to obtain a three-dimensional image of the object.
