基于三频相移的结构光测量系统
3D Optical Measurement System Based on Three Pitches Heterodyne Method
摘要
Abstract
measurement system based on phase shif structured light has been widely used in the field of reverse engi-neering.Traditional gray code is combined with the four-step phase shift raster transmission,because the periodic mutation of phase and bad edge effect will be caused by phase unwrapping algorithm.Seven multi-frequency grating heterodyne trans-mission frequency,Phase Unwrapping based on single point to avoid the periodic mutation,lack of need to collect more pic-tures.To solve the above problems based on structured light measurement of triple-frequency phase-shifted,in projection grating as little as possible at the same time,single point solution phase.Experimental validation,the system can complete complex surface measurements and to obtain high accuracy point cloud data.关键词
