Paper Abstract

Several photos of projected gratings patterns should be taken from different angles, when 3D topography of revolving objects is measured by grating projected method. How to combine the measured data of grating projected patterns is a key factor of measuring 3D topography of revolving objects. A new data combination method, which is based on cylinder coordinate transform, is proposed in this paper. The equations and operating steps are introduced and the experiments are given in this paper. All the projected gratings patterns are processed by FFT phase technique.
