In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.
