Paper Abstract

A fast and efficient technique for full-field dynamic 3-D measurement with color three-frequency fringe pattern projection is proposed. The technique is based on RGB color fringe pattern projection and empirical mode decomposition algorithm Using temporal unwrapping method the true phase distribution with high precision is acquired to recover the height distribution of the object. The technique permits the three-dimensional shape measurement of objects that have large height-discontinuity or spatially isolated surfaces. Owing to requiring only a single snapshot; it makes possible the instantaneous three-dimensional shape measurement of discontinuous objects in fast motion.
