摘要
研究了在Geomagic环境中通过三维点云数据重建三维实体模型的过程,详细介绍了复杂实体点云数据在Geomagic中点云数据处理的全过程,包括点云匹配、点云预处理、封装形成三角面、在多边形阶段破洞修补以及优化处理,最终生成了NURBS曲面。三维重建过程表明,在Geomagic中重建三维模型不仅效率高、精度高,而且软件易于操作。本文涉及的数据处理方法也可以用于三维激光扫描技术在数字矿山、数字城市中应用。
Contents of this paper is to reconstruct a three - dimensional solid model by 3D point cloud data in Geomagic environment process. This paper describes the whole process of complex physical point cloud data in Geomagic, including match point cloud, point cloud pre - processing, packaging form a triangular face, and repair holes in polygon optimization stage, and ultimately generate a NURBS surface. Three - dimensional reconstruction process showed that the reconstruction in Geomagic models are not only high effi-ciency ,high precision, and the software is easy to operate. This paper relates to data processing method can also be used for three - dimensional laser scanning technology for digital mine and digital cities have applied.
