摘要
在反求工程中,对于重建模型表面与点云之间的误差,通常采用UG的测距分析功能,逐点分析点到表面的距离,来判断所建曲面的精度。利用UG的二次开发工具GRIP,能够批量实现点云中的点与重建模型误差的统计分析,为评价模型精度找到了一种有效的方法。
In Revense Engineering, UG ＂analyse function＂ is ofen adopted to measure the distance from point to surface one by one to estimate precision of surface. To use the second development tooIs of GRIP in UG, an effective method was found to realize the error statistic from point cloud to model reconstruction.
