摘要：
Modulation is used to scalage the phase unwrapping reliability and it is related to the measured object's gray and shape informations. A novel on-line three-dimentional (3D) shape measurement method based on modulation delamination is presented. While one sinusoidal fringe is projected on the measured object, the deformed patterns with equivalent phase shift are captured as the measured object moves. The corresponding modulation distributions to the deformed patterns can be obtained by Fourier transform profilometry. A modulation delamination method is used to extract a token from modulation distributions as the mask, and the pixels matching can be realized so as to achieve the equivalent phase-shift deformed patterns at the same pixel coordinate. So the on-line 3D shape measurement is realized. Experimental results show the feasibility and validity of the measurement method.
