Abstract

Digital fringe projection technique is widely used for high-accuracy three-dimensional (3D) shape measurements. However, when the measured object is moving, there will be severe artifacts and phase errors induced by the movement even though a high-speed fringe projection system is used. Meanwhile, there are different kinds of motion such as uniform and non-uniform motion, which makes the problem even harder to address. To this end, this paper proposes a generic motion error compensation algorithm to deal with different motion artifacts. Both simulation and experiments demonstrated the proposed method can substantially reduce motion-induced measurement error.
