In reverse engineering,the point data get from optical measurement is only part of object from one angle of view.To get the entire point data,the object should be measured from different angle of view.The most of algorithms about 3-D surface matching is based on topology feature.However,as to the non-feature or less-feature surface,the algorithms are not effective and accurate.Adding Extern feature is an approach to solve the problem above,while the compute complexity is large.In this paper we present a method for point cloud matching based on non-coded mark point whose geometric center is extracted from the digital image.The center of mark point is the local corresponds of two surfaces.
