Abstract

The point cloud data on a scanning line from laser scanning system has the same value in one dimension. According to this characteristic, an algorithm of surface reconstruction based on non-uniform B-spline 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 splitting, sorting and slicing are used. The least square non-uniform B-spline is used to smooth and interpolate the data of the section point cloud, then the data of reconstructed surface can be achieved after a secondary sampling. An example of the rearview mirror of motorcycle is given to testify that the method is effectual and feasible.
