It is necessary to improve the efficiency of point cloud deviation';s visual expression during the inspection of free-form surface based on solid CAD model.A new method was proposed that use K-D tree to describe the deviation of the point cloud to solid CAD model approximately.Differing from the exact description of the deviation calculation,the method firstly facets the surface of inspection in a certain resolution to make a point cloud of the CAD model,then uses the strategy of K-D tree';s divide and conque...
