Currently,in reverse engineering,the data processing approaches for 3D point cloud data are based on data topology.The algrithm here aimed at the unordered,with no topology relationship,3D scattered point cloud data.First,adopting the frequency method in probability statictics,the noise data could be found from the scattered data;then,through the K-D tree space estblished based on the 3D data,the k nearest points around noise point were found and through the information of these k points,the real information of the noise point was recovered.The laser 3D plane scanning robot system has demonstrated its effectiveness and it is feasible in pre-processing of data in reverse engineering.
