为了确定三坐标激光测量的最佳参量组合, 获得较好的测量效果, 采用正交实验法进行了理论分析和实验验证。在选取实验中设置的第10档最快速率、频率选取为30Hz、景深水平选取为最佳景深、角度垂直于被测工件表面的参量组合下, 测量效果最佳。结果表明, 该研究中参量选择从定性跨越至定量, 可有效改善三坐标激光测量过程中参量选取难的问题。

In order to determine the optimal parameters for three-coordinate laser measurement, and get better measurement effect, theoretical analysis and experimental verification were conducted based on the orthogonal test. The best performance could be achieved under the conditions of speed at the tenth fastest set, frequency at 30Hz, optimum depth-of-field and angle perpendicular to the surface of the workpiece. The results show that it becomes easy to choose parameters in the three-coordinate laser measurement, after qualitative analysis and quantitative analysis.
