摘　　要：针对当前室内三维重建没有同时顾及内、外拓扑和建筑部件语义的问题,该文提出了一种顾及拓扑的室内三维薄壁模型重建方法。该方法在已有的二维数据基础上,利用“推拉”操作,直接生成保留语义的室内薄壁三维拓扑数据模型,并通过实验进行了验证。结果表明,该方法生成的三维模型保留了墙、门、窗等建筑部件,并顾及了内、外拓扑,能够快速生成室内薄壁三维模型,为室内导航、室内应急等应用提供了模型基础和方法借鉴。Aiming at the problem that the indoor 3Dreconstruction did not consider internal and external topologies,the semantics of building components simultaneously,a method for reconstructing 3Dthin-wall model considering topology was proposed.On the base of the existing 2Ddata,the method used extrusion to generate indoor thin-wall 3Dtopological model preserving the semantics of wall,door and window directly and verified by experiments.Results showed that the 3D model generated by this method retained the building components such as walls,doors and windows,and took into account the internal and external topologies.It could quickly generate indoor thin-walled 3D models and provided a model basis and methodological reference for indoor navigation and indoor emergency applications.
