基于激光点云的合浦汉墓出土陶屋三维重建

3D modeling of unearthed pottery house from Hepu Han tomb based on LIDAR

以LMS-Z420i三维激光扫描仪为例,给出了一种扫描站点与反射片设计、激光雷达数据与数码相片的配准、数据采集和预处理的方法;然后分别阐述2种不同类型的三维建模的方法:其一为通过基于Micro Station的三维建模插件Phidias的规则建模方法,另一种为基于Geomagic软件的三角网的建模方法;最后以合浦汉墓出土的陶屋为例来实现,给出2种建模方法获得的粘贴了纹理的模型.结果表明,规则模型能很好的反映陶屋的结构与比例,但不规则的模型能够很好的反映陶屋的现状.

Taken Riegl LMS-Z420i for instance, the site design of laser radar station and reflective pieces was introduced. Then, laser radar data and digital photo registration, data acquisition, data processing was given. After that, two method of 3D modeling were stated, one used the modeling method of 3D modeling software Phidias based on MicroStation; the other based on triangular mesh. At last, it took pottery house from Hepu Han tomb as an example, 3D model of pottery house was come true. The result showed, rule model reflect the structure and proportion of the pottery house well, but irregular model reflect the status of pottery house.
