| Abstract: | Based on Fourier Transform Profilometry, wavelet filter is used to analysis 3-D shapes of objecte. A series of non-linear filters for analyzing the grating image are created by ueing a log Gabor function, then get the phase information, which can make the measurement automatically and improve the precision. Simulation and experiment results are presented. |
