Three-dimensional measurement of large-scale texture-less bending plates

摘要

A three-dimensional (3-D) measurement method for large-scale bending plates is presented. The proposed method, which combines the advantages of laser and a vision measurement method, makes use of a 3-D scanner, a texture projector, and a laser total station. The 3-D scanner is used to measure multiple partial sections of a large-scale bending plate, the texture projector is used to project a textured pattern onto the bending plate to perform alignment, and the total station is used to correct the aligned result to obtain more accurate 3-D data. The performance and effectiveness are evaluated by experiments. (C) The Authors. Published by SPIE under a Creative Commons Attribution 3.0 Unported License.
