    Abstract

    Color-coded structural light system can reconstruct the 3D contour of the object in one shot by the using of three different patterns embedded into three color channels of the projector and camera. However, it cannot reconstruct a color object, and the crosstalks between different channels lower the accuracy. A novel color-coded structural light system is presented. By using multiple cameras and well designed beam splitter prism and filter, color crosstalk between different color channels in color-coded structural light system is eliminated. A process of two-shot acquiring color object prefile based on three-step phase measurement profilometry is analysed. Color calibration method is discussed to improve the system′s accuracy. After all the procedures, a colorful object can be reconstructed in two shots, which combines the speed and accuracy.
