Title:
STRUCTURED LIGHT-BASED PROJECTION METHOD AND SYSTEM FOR THREE-DIMENSIONAL SCANNING PROJECTION LINE
Document Type and Number:
WIPO Patent Application WO/2024/077644
Kind Code:
A1
Abstract:
A structured light-based projection method for a three-dimensional scanning projection line, relating to the technical field of three-dimensional information reconstruction. The method comprises: in three-dimensional measurement, performing periodic switching or random switching among different projection image groups so as to acquire a plurality of continuous projection image groups (S101); projecting a plurality of images of the projection image groups to a surface of an object to be measured (S102); imaging the projection images projected onto the surface of said object to obtain a resulting image (S103); and decoding the resulting image to determine correspondences between imaging positions and projection positions, so as to reconstruct three-dimensional information of the surface of said object (S104).
