在一种泛型的3D最小二乘表面匹配模型基础上，讨论三种主流的共轭点对应准则，及其对表面匹配精度的影响分析。针对真实航空激光雷达点云数据进行配准对比实验，结果表明三种表面间共轭点对应准则都能较准确地估计出相邻重叠三维表面间的正形变换参数，其中最小法向距离准则在大多数情况下能获得相对较高配准精度。

In this approach ,three conjugate point rules between two overlapped surfaces are discussed ,based on a general least squares 3D surface matching model .We explain how these methods can be used for the co-registration of two real 3D point sets ,and show co-registration results based on airborne laser scanner data .Concluding results of our experiment suggest that every proposed conjugate point rules has a good performance for transformation parameters estimation in 3D surface matching procedure . In many cases ,the least normal distance can achieve best result in practical matching .
