基于点云数据的三维重建
文章的第二章，从三维激光扫描数据的特点出发，介绍了数据处理的基本程，重点介绍了预处理的内容：其一，介绍了使用FARO Laser Scanner 880的套软件FARO Scene和商业软件Geomagic Studio对点云数据进行去噪的方法步骤；其二，介绍了多站数据配准的基本理论和几种重要算法，包括：有靶控制的点云配准方法、ICP算法和四元数法，并归纳了这几种方法的特点。第三章主要研究了基于塑像三维点云数据进行模型重建的技术。针对塑像面不规则的特点，对塑像点云的建模选择了逐点插入法构建空间三维网格，细介绍了该算法和流程；针对三维激光扫描数据量大的特点，提出了基于构不均匀网格
