Abstract :
The study is on a calibration method for grating projection plane in 3D image measurement system and discussing the problems need to be noted in application. It brings forward a new method for curving surface based on 3D on-line measuring points, according to the on-line distribution rule of 3D points group on the grating projection measuring system. In portrait image reconstructing, this method can generate good-character triangles, avoid missing points, cracks or holes and produce a smooth and consecutive curving surface.
