摘要
随着BIM技术及其应用的快速发展,IFC标准的BIM模型已经成为一种重要的室内三维模型数据源。其详尽的几何语义、要素材质、功能信息及各要素之间关联关系,能为室内导航提供较充分的数据支持。本文基于IFC,设计实现了一种面向导航应用的IFC建筑模型室内空间信息提取方法,针对各个室内要素,通过几何过滤、语义清洗及楼层映射对IFC建筑模型进行一体化的提取,利用典型的复杂三维建筑物模型进行实验分析,提取导航所需的室内要素,验证了其正确性与有效性。
With the rapid development of construction field and the wide use of BIM model, IFC standard BIM model becomes a new kind of indoor sources. The details of geometry, semantic, elements material, function and the relationship of the building elements provide powerful data support for indoor information extraction. IFC is the data standard widely used in the BIM field. This paper based on IFC model and proposed an indoor information extraction method for indoor navigation. The method involved the geometry filtering, the semantic cleaning and floor mapping to extract the IFC architectural model, using a typical 3D building models of complex experimental analysis, extracted the interior elements for navigation and its correctness and effectiveness are verifed.
