Abstract：In reverse engineering technology,point cloud registration technology is particularly critical for 3D reconstruction of objects.To meet the requirements of matching local similar features of different point clouds in assembly scenes,a fast registra-tion algorithm for low overlap point clouds based on improved ICP is proposed.The algorithm first extracts the key points of multi view NARF and ISS.At the same time,3DSC feature descriptors are added to add key point information,and SAC-IA algorithm is used to complete fast rough registration.Finally,the latest iterative ICP algorithm is used for fine registration of the sampled coarse registration point cloud.The experimental results show that the registration rate of this algorithm is greatly improved the registration accuracy and rate.
