Paper Abstract

Traditional phase shifting shape measurement techniques not suitable for dynamic measurement because it need a certain number of pieces of fringe pattern. In this paper, the basic principle of the fringe projection shape measurement technique was introduced, the method of single fringe pattern phase extraction by Hilbert transform was discussed, and conducted three-dimensional shape measurement tests. Experimental results show that 3-D shape measurement can be achieved by Hilbert transform phase-shifting, and it suitable for dynamic measurement.
