摘　　要：使用Geomagic Studio对摩托车覆盖件点云数据进行降噪及归一化处理,并封装为三角形网格。将得到的NURBS曲面导入至交互式CAD/CAM系统Unigraphics NX中进行曲面缝合及轮廓修整。最后在Geomagic Qualify软件中对获得的三维模型和原始点云进行逆向校核,获得了较好的试验效果。The motorcycle cover point cloud data is denoised and normalized using Geomagic studio,and packaged into a triangular mesh.The resulting NURBS(Non-Uniform Rational B-Splines)surfaces are imported into the interactive CAD/CAM system Unigraphics NX for stitching and contour trimming.Finally,the obtained 3D model and original point cloud are reverse checked in Geomagic Qualify software,and good experimental results are obtained.
