Abstract：

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.
