| 摘 要： | 基于人工标志的公共点法是中远程地面三维激光扫描仪常用的点云拼接方法。目前,该方法还是手动或半自动,人工交互较多。本文对公共点自动拼接中的标志匹配进行了研究,提出一种基于欧式变换不变量的匹配方法。该方法不需借助编码等其他辅助手段,匹配效率高,非常适合扫描标志的匹配。

| Abstract: | Target-based registration method is widely used in Terrestrial Laser Scanner with middle and long range,unfortunately,this method is in a the manual or half-automatic stage at present,which results in too much alternation.In the paper,a study was carried out on automatic matching of scan targets in target-based registration method,and a method based on transformation invariance was put forward.This automatic matching method could be done in an efficient way without any assistant,so the conclusion is that th... |
