THREE-DIMENSIONAL IMAGE RECONSTRUCTION METHOD AND APPARATUS BASED ON DEBRUIJN SEQUENCE

摘要

Disclosed are a three-dimensional image reconstruction method and apparatus based on a DeBruijn sequence. The method comprises: using a shift register to generate a four-element two-level DeBruijn sequence (101); carrying out binary conversion on the DeBruijn sequence to obtain binary sequences, and filling the binary sequences in a gray area in a pre-set template image in sequence to obtain a coded template image (102); carrying out image collection after the coded template image is projected onto a surface of an object to obtain a coded image including coded template image information and object information, and binarizing the coded image to obtain a first binarized image, wherein the first binarized image comprises a plurality of coded feature points, and each of the coded feature points comprises one central area (103); based on the first binarized image, determining position information about the central area of each of the coded feature points (104); and based on the first binarized image, and the position information about each central area, determining a coded value of each of the coded feature points, and using the coded value for three-dimensional image reconstruction (105). A higher anti-noise capacity and better robustness are achieved when the method is used for three-dimensional image reconstruction.
