The acquirement of 3D geometric information is the most important for reverse engineering. With these advantages such as no phase shift error, rapid measurement, easy to carry and high precision, the three-dimensional(3D) measurement system which is based on phase shifting technology using digital fringe based DLP projection has been widely used in the object three-dimensional shape measurement.The precision of camera calibration determines the measurement accuracy of the system. In this paper, an improved flexible camera calibration means is presented than Zhang’s planar flexible calibration method. By applying the phase-shift technique to fringe projection, point clouds with high spatial resolution and limited accuracy can be generated.In the locomotive casting mold design and processing, error detection of the mold is a very important step. In this paper the principle of the measurement system based phase shifting using digital fringe and the algorithm of ICP is discussed, which is used in the locomotive casting mold design and error detection. Keywords-locomotive casting mold; phase shifting; digital fringe; camera calibration; ICP algorithm
