Title:
THREE-DIMENSIONAL RECONSTRUCTION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/032670
Kind Code:
A1
Abstract:
Disclosed in the present application are a three-dimensional reconstruction method, apparatus and system. The method comprises: acquiring a first image and a second image, wherein the first image and the second image are respectively obtained by means of different image collection devices collecting a predetermined symbol image projected onto the surface of an object to be subjected to measurement, the predetermined symbol image including a plurality of target symbols that are randomly distributed in a preset direction, and the target symbols being line segment stripes; acquiring a first target pixel point of each symbol in the first image, and determining, in the second image, a matched pixel point for the first target pixel point of each symbol in the first image; and determining the three-dimensional coordinates of the first target pixel point at least according to the predetermined pixel coordinates of the first target pixel point in the first image and the predetermined pixel coordinates of the matched pixel point in the second image, so as to complete three-dimensional reconstruction.
