Considering the characteristics that point cloud data obtained by laser scanning system has the same coordinate values in some dimension, the triangular B-B surfaces reconstruction technique is proposed. For the preprocessing of the initial 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 method is used to smooth and interpolate the section point cloud data, then the data of reconstructed surface can be achieved after a secondary sampling. An example of the mouse is given to testify that the method is effective and feasible.
