| 摘 要： | 分析了异构建筑在三维拓扑重建中的问题,依据拓扑数据模型的需求,提出了基于顶图、底图和结构图的自动拓扑重建算法,该算法能够有效地对异构建筑进行整体三维拓扑重建,不仅保留了建筑内每一实体单元的内拓扑,同时也兼顾了实体间的外拓扑。基于该方法,设计并开发了三维地籍管理系统中的数据生成模块,以深圳市某小区为实验区,验证了算法的可行性及有效性。

| Abstract: | We analyze the problems in the 3D topological reconstruction of the heterogeneous buildings and put forward the calculation method of the automatic topological reconstruction based on the requirements of topological data model,the roof plan,the floor plan and the structural plan.The calculation method shall be able to effectively take the 3D topological reconstruction for the heterogeneous buildings,and thus it does not only maintain the interior topology of each real unit within the building,but also consi... |
