Abstract
A new method of fast on-line 3D measurement is proposed.A modulation delamination method is used to extract a token from object modulation distributions.With the token delamination information transformed into integer as the mask,the equivalent phase-shift deformed patterns at the same pixel coordinate can be realized by the pixels matching,which puts the fast on-line 3D measurement into practice.To verify its feasibility and validity,a contrast experiment on this method and a method based on a particular region of modulation distributions are carried on.Experiments show that the high-veracity of the algorithm and the speed of on-line inspection can be effectively improved.
