A rapid color structured light 3D measurement technique is proposed.Based on the principle of gray code,a novel color coding method using 6 easily distinguished colors is designed.An exclusive sequence of encoded color stripes is presented,whose beginning postion of the periods can be discretionary and the inter-symbol interference is avoided.Furthermore,the decoding process is facile.The traditional three-phase shifting is replaced by three-colors phase shifting.By using two color structured light images,3...
