【摘要】 逆向工程作为产品制造的一种手段,可以将符合要求的汽车覆盖件零件进行测量并反求出零件的三维模型。本文采用逆向工程技术,通过3DD-300型三维激光非接触扫描仪得到覆盖件的点云图,在PRO/E中完成了点数据的处理、曲线和曲面的构建、修边等工作,利用小平面特性最终生成了覆盖件的三维模型。更多还原

【Abstract】 The reverse engineering is considered one means of manufacture.It can measure the part of the automotive panel and reconstruct its model.The panel point cloud data was done by the 3DD-300 laser scan instrument using the reverse engineering technology.The panel 3D model was given in PRO/E by the point-data processing,the curve and panel constructing,trimming and small plane feature更多还原
