Research on Phase Unwrapping Based on Color-coded Light technique
Optical three-dimensional (3D) measurement technology is one of the most active research topics in computer vision.Based on the theory of phase shift processing and color-coded light,a new unwrapping method which can measure the 3D-body with a high speed was proposed.First,the period distribution was got by the 4 bits binary-coded color pattern projection technology; then the phase collapsed in the range (-π,π) can be obtained with the method of four step phase shift; finally exact phase can be computed by combining the phase shift processing and color-coded light method.The experimental results proved that the new method can reduced the number of the coded light and the true,exact phase can be obtained,and the 3D measuring speed can be highly improved.
