摘要：

在使用点云数据或三角网格数据表示的自由曲面的配准问题中，ICP算法使用相当广泛，但就实际应用来说，基本的ICP匹配算法存在一定的缺陷。针对基本ICP匹配算法存在的固有限制，本文采用先粗后精的匹配思路，即先用能量法进行数据间的粗略配准，以粗配准的结果做初始值，利用ICP算法进行数据间的精配准。并用实际工件的成形例子对配准算法进行验证，其全局优化性能优于ICP算法。

In the registration of freeform surface which is represented by point cloud or triangular mesh，ICP algorithm is used widely, but in practical applications, the basic ICP algorithm has some defects. According to the inherent limitations of basic ICP matching algorithm, the registration algorithm based on two steps method was given. At first step, the energy registration method was employed to align the data in different coordinate system, and then ICP algorithm was employed to register the data precisely by using the result of energy as the initial value. The forming examples of the actual workpiece was used to verify that the property in global optimization of the registration algorithm based on two steps method is better than that of ICP algorithm.
