摘要
三维激光扫描技术是当前的一种新技术,其仪器的精度评定方法还不完善,提出两种三维激光扫描单点定位精度评价方法,即外部符合精度评价方法和内部符合精度评价方法。介绍了两种方案的实施过程,并且通过实验进行了分析,得到了较好的评价结果。
3D laser scanning technology is currently a new technique. Evaluation of the precision equipment is not perfect. This paper presents two three-dimensional laser scanning point positioning accuracy of evaluation methods, an external evaluation method and accuracy of echo within the accuracy of echo evaluation methods. Results show feasibility and validity of the approach.
