A high-speed 3d measuring system using DMD was presented in this paper.This system could scan 3d objects with high speed and high resolution.So,the requirements of motion states of the measured objects are reduced.Then 3d surface is reconstructed with ball-pivoting algorithm.Finally,crystal internal sculpture is obtained by using laser internal sculpting machine.In the experiments,the measurement speed of high-speed 3d measuring system reaches 90fps.The 3d data of face was collected and its crystal internal sculpture was produced successfully.For the popularization of crystal inside carving of dynamic real objects,the high-speed 3d scanning system provided effective technical means.
