NURBS Surface Reconstruction of Point Cloud from Laser Scanning System
Pengnan Li · Journal of Hunan University of Science & Technology · 2006
The point cloud on one scanning line from laser scanning system has the same value in one dimension. Based on this characteristic, an algorithm of surface reconstruction based on NURBS is put forward. For the pre-processing of the original point cloud, the points that don't belong to the surface are deleted, and the methods of split, sequencing and section are used. The least square non-uniform B-Spline are used to smooth and interpolate data to the section point cloud, then the data of reconstructed surface is achieved after a secondary sampling. An example of a mouse is given to testify that the method is effectual and feasible. 4refs.,7refs.
