基于自由曲面点云的快速原型制作技术研究注意:本论文已在《机械工程学报》2003,39(1):56-59,83发表 摘 要: 针对不附加任何拓扑和几何信息的云状数据三维重建问题,提出了对点云直接进行分层处理快速制作原型的新方法。在对点集进行空间结构划分的基础上,采用最小距离关联点对方法提取层面轮廓线数据,并对其加以匀化和精整从而直接生成快速成形机的层片接口文件,避免了常规方法存在的耗时和需要很高的造型技巧等不足,而且片面的错误校验与修补等繁琐工作也将不再进行,提高了快速成形前处理的效率,非常适合分层实体制造(LOM)等成形工艺。 RAPID PROTOTYPING MANUFACTURING BASED ON CLOUD DATA FROM FREE-FORM SURFACE SunYuwen Jin Zhenyuan Abstract: Physical model
recovered from cloud dada only with coordinate information is of great
importance in the integration of reverse engineering and rapid prototyping
technology. A new method, that rapidly generates prototype from sampled
points, is proposed. Based on establishing the spatial partitioning representation
of point cloud, the contour data in each layer is firstly calculated and
sequenced, then amended to generate exact slice file. It overcomes lots
of drawbacks in traditional integration such as consuming time and needing
expert modeling skills. Moreover, without the intermediate transactions
of STL file, the work of checking and repairing mistakes of facets is
avoided. It is very suitable for laminated object manufacturing and greatly
improves the pretreatment efficiency of RP technology.
