A two-dimensional three-frequency phase resolution measurement method based on colored structured light, the steps are: ① Prepare three gratings composed of two different three primary color sinusoidal lights with the same frequency; ② Project the grating onto the measured object, using two The same CCD camera was taken to obtain 24 photos; ③ Dephase the photos taken to obtain the phase values ​​in the X direction and Y direction of each pixel on each photo; ④ Match the two phase values ​​to calculate each The 3D coordinates of the point. The invention overcomes the defects of coding in only one direction and the shortcoming of low matching precision, so that the coding matching is more effective and accurate. It avoids the measurement error caused by contact deformation in the mechanical measurement method, and improves the measurement accuracy; it does not need to obtain three-dimensional information through two-dimensional scanning, which improves the measurement speed; it can record the color information of the object at the same time, so that the reverse engineering can be obtained from the three-dimensional object The acquisition of shape is further extended to the inversion of object color.
