Abstract

Fast fringe projection 3D measurement system using a generalized phase-shifting method with a continuous fringe scanning scheme is proposed. Fast measurement can be performed owing to the continuous fringe scanning scheme. An object phase is obtained by a generalized phase-shifting method using normalization of randomly phase-shifted deformed fringe images. We conduct experiments on measurement of small deformation in muscle tendon of human hand during mouse operation. Experimental results indicate that the proposed method can quantitatively measure the deformation of human hand.
