摘要：In structured light 3D measurement field, when the object hassmooth surface, it can form a highlight area due to the specular reflection, and the distortion of the object will make a large measurement error. In order to solve this problem, this paper use seven stepssine-phase shift combined with linear diffuser to remove highlight. Firstly,the principle of removing specular with diffuseris analyzed,then the overall design of the system is introduced, which includes 3D reconstruction and system calibration method. Finally the reconstructed experiments are carried out with ceramic plate. Experimental results show thatthe proposed method can significantly reduce the highlights area of reconstructed image compared with the highlights area without diffuser. The diffuser can obviously inhibited by highlights, although it can not completely remove the highlights, it plays a very important role in reconstructing specular objectwith more accurate and better quality.
