| Abstract: | In this paper, this method can get the point cloud data through the handheld laser scanner, the data are merged by the principle of datum point positioning, after the processing of the polygonal mesh, the NURBS patches are established finally. Then make error analysis and revised again on the reconstruction, which can meet the requirements of the digital model. Point cloud data can be processed and the 3D complex model can be established quickly by this method, also can meet the application of CAD/CAM systems. |
