基于3DGIS的古建筑物的三维数字化保存研究

Research on the 3D digital preservation of ancient buildings based on 3DGIS

针对传统古建筑物存档保存保护形式存在的不足,提出了利用免棱镜全站仪获取古建筑物的三维坐标数据的方法,根据获取的古建筑物三维坐标数据,利用AutoCAD和3DMAX对古建筑物进行三维建模,再将三维模型在3DGIS中进行纹理粘贴和古建筑物有关工艺、材质、工程等属性数据的输入,不单纯实现了古建筑物视觉上的三维可视化,而且实现了古建筑空间和属性信息的管理、查询和分析,从而实现了真正意义上的古建筑物三维数字化保存。

The existing methods have some shortcomings in the protection and preservation of ancient buildings. In this paper, the 3 D data of ancient buildings is surveyed by non-prison total station, and the 3D model of ancient buildings is established by AutoCAD and 3DMAX. Then 3DGIS is used to paste the texture on the 3D model of ancient building and input the attribute information of materials and technology about the ancient building into the 3D model. This not only realizes the 3D visualization of ancient buildings, but also achieves the management, query and analysis of ancient building space and attribute information, thus achieving the 3 D digital preservation of ancient buildings.
