基于本体论的城市构筑物三维描述

Three-Dimensional Expression of City Construction Based on Ontology

为了解决城市构筑物空间描述现有方法存在的空间目标划分和表达困难的问题,应用本体论的基本理论———部分-整体关系,分析了城市构筑物的描述层次和几何定义;从部分和整体两方面对空间实体的联系进行了分析,提出了一种基于本体论的城市构筑物三维描述框架,并用V isual C++语言和OpenGL Perform er图形软件包实现了原型系统.

To overcome the difficulties in the appropriate partition and expression of spatial objects in the existing spatial description of city construction, the describable hierarchy and geometric definition of city construction were analyzed with the help of the basic theory of ontology-part-whole relation. In addition, the relationship between spatial entities was discussed from two aspects of part and whole. Finally, a new three-dimensional description frame of city construction based on ontology was put forward, and the related experiment system was designed by utilizing Visual C ＋ ＋ computer language and OpenGL Performer, a graphical software package.
