【Abstract】 How to combine the measured data of grating projected patterns is a key factor in 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. All the projected gratings patterns are processed by FFT phase technique.更多还原
