3-DSensingUsingSinusoidalFringeProjectionandPhaseUnwrapping
With four step phase shifting method the 3 D surface profile of a coin was measured using sinusoidal fringe projection produced by a liquid crystal display (LCD) projector. The phase unwrapping problems are discussed. A new method for detection of the phase discontinuity area and a new technique for phase unwrapping are presented. The experimental results are given.
