In reverse engineering, in order to meet the requirements for model reconstruction, it is often necessary to locate and merge the different view measured cloud data in a global coordinate system. Firstly, an enhanced ICP algorithm is proposed to register precisely the pair wise views without explicit point to point matches. On the basis of pre registration with labeling method, a nominal correspondence has been created between the controlled point sets selected from the different positions in the overlapped view area, and the transformation can be achived by iterative method. Afterwards, a synchronous method is also presented to implement multi view registration and integration, which will reduce the accumulative error caused by sequential registration. Finally a weighed average algorithm is utilized in the shrunk bounding box of the overlapping area to integrate all the sets of views, and the effectiveness of the methods is validated with experimental results.
