石窟寺三维数字化档案建设方法与技术探讨

文物是不可再生的文化资源,需采用现代科技手段对其进行数字化保护,延续人类历史文明。本文以彬县大佛寺石窟为例,在已有基础地理信息数据、三维激光扫描数据、立面影像数据的基础上,运用CAD建模技术、三维激光扫描技术、虚拟现实技术构建石窟寺三维立体模型,借助CityMaker软件对模型数据、基础地理信息数据及文档资料进行管理。在此基础上,采用基于GIS组件的二次开发方法,借助于CityMaker SDK组件进行三维数字化档案系统开发,探索石窟寺三维数字化档案的建设方法。结果表明,本文提出的方法实现了对石窟寺三维数字化档案的管理,客观详实地记录了石窟寺现状,为文物部门的管理工作提供了便利。

Discussion on the 3D Digital Archives Construction Method and Technology of Cave Temples

In order to continuation of human civilization, cultural relics as non renewable cultural resources, need digital protection by modern means of science and technology. In this paper, Bin County Cave Temple as an example, a variety of technical means like CAD modeling technology, 3D laser scanning technology, virtual reality technology, are used to con- struct cave temples 3D model based on existing basic geographic information data, 3D laser scanning data and facade image data. Then cave temples 3D model, basic geographic information data and documentation are managed by CityMaker. A 3D digital archives construction method is explored, which is a 3D digital archives system developed with the help of City- Maker SDK. The result shows that the management of cave temples 3D digital archives becomes true by the method which record objective status. It can provide convenience for the Department of administration of cultural relics.
