利用光栅投影法进行三维测量有良好的发展前景,但仍未能很好地解决高精度测量问题。提出结合相位高度映射关系和棋盘标定法的三维测量方法,该方法基于数字光栅相移技术,减少了对数字光栅和CCD几何约束要求,操作简单,实现对被测物三维信息的测量与重构。对已知高度为20 mm的参考物体进行测量,高度相对误差为0.727 5%。实验结果表明,该方法快捷高效,精度高。

Although three-dimension（3D） shape measurement based on digital grating projection has a good development prospect,the problem of high accuracy measurement cannot be solved.Combing with height-phase mapping and lattice calibration,a 3D measurement method is proposed.The Geometric constraints of digital-grating and CCD are decreased.The measurement system is more feasible,which can be used to realize the accurate measurement and reconstruction according to the 3D information of measured object.By applying the proposed method to measure a 20.00 mm height reference object,the relative error is 0.727 5%.The experimental result shows that the method is efficient and precision.
