Abstract
Phase measuring profilometry is an important measurement method of the optical 3D measurement system, in which the projector is used in the grating fringe projection. Then there are some shortcomings to the projector used in the projection process. In this paper, the physical grating equipment based on the design of a projection is designed and structural parameter to filming machine is optimized. It indicated that the new method is effective method to overcome the projector appear to improve the measurement accuracy.
