Paper Abstract

Fourier Transform Profilometry and Phase Shifting are two important methods in 3-D measurement of body. Phase-shifting requires exact Phase-shifting sets, and more than an image collected, therefore its application is limited. Fourier Transform Profilometry required only an image, and calculated phase value of each point, measurement is higher degree of precision and wide range, its application is not limited. Wavelet Digital Filter and Fourier Transform Profilometry are combined, higher spectrum and direction components removed, kept useful components, raised dividing phase degree of precision, phase information of measured body resolved. This paper presents the analysis above the calculus and the results of simulated experiment.
