Hybrid light measurement method for measuring three-dimensional profile
A hybrid light measurement method for measuring a three-dimensional profile comprises: Step 1 using a MEMS laser projector to realize projection of a laser stripe and a fringe pattern: and Step 2 performing matching to obtain a parallax, and incorporating a binocular stereo vision to perform reconstruction. The present disclosure employs MEMS projection technology to realize a hybrid measurement system capable of performing laser stripe measurement and fringe pattern measurement, thereby realizing quick measurement of three-dimensional profiles of objects having different surface properties. The present disclosure enables laser stripe measurement and fringe pattern measurement to be performed by the same measurement system without needing any additional hardware equipment. The projection device used in the present disclosure enables projection of multiple laser stripes, thereby increasing measurement precision and speed.
