三维点云数据的准确配准拼接与坐标转换是确保大型建筑物重构精度的关键.文章利用Scan Station2三维扫描仪对大型建筑物进行多测站扫描与配准拼接,分析了平面标靶与特征点配准的误差来源,提出了改进的特征点配准方法及坐标转换策略,并实例验证了该方法的有效性与优越性.

英文摘要：

Registration and coordinate transformation of 3D point cloud data are keys about guaranteeing huge building reconstruction precision. Scan Station2 scanner was used to scan huge building and register scanning data. The source of error was analyzed that about matching plane targets and feature points,and an optimized approach of matching feature points was put farward and an optimized strategy of geodetic coordinate transformation was realized,and instances were run to verify effectiveness and superiority of these strategies.
