Paper Abstract

Non-contact three-dimension (3D) measurement technology has developed rapidly. Digital grating projection is regarded as the best prospect one. There are many problems, such as low accuracy, which have not been solved yet. Based on digital grating phase-shift, and combed with height-phase mapping and self lattice calibrating, a new 3D measurement method has been proposed. With little geometric constraints to digital grating and CCD, the measurement system is more feasible, which can be used to realize the accurate measurement and reconstruction according to the 3D information from measured object. By applying the method proposed to a reference object, the experience has lead to good result which shows that the new method is efficient and precision.
