Geometric Information Loss Measurement Method for BIM to GIS 3D Model Conversion
建筑信息模型(building information modeling,BIM)是智慧城市重要的数据源。但由于其语义信息结构复杂,以及其IFC标准与GIS的CityGML标准的差异性,难以与GIS集成,极大地限制了BIM的应用及智慧城市的建设进程。这也导致BIM与GIS三维模型的转换必然存在信息的损失问题。不同的应用对BIM转换过程中的信息损失量的容忍程度不尽一致。目前,鲜有BIM与GIS模型转换过程中几何信息损失量的度量方法的研究。本文以IFC标准下BIM模型与GML标准下GIS三维模型转换为例,提出了两种标准下模型转换过程中几何信息损失的三种度量方法,并对转换损失进行综合评估,研究成果为BIM应用及智慧城市建设与精细化管理提供有效的数据转换质量参考,为后续信息损失控制方法的研究提供依据。
Abstract
BIM is an important data content for smart cities. Due to the data standards of BIM, it is difficult to integrate with GIS, greatly limiting the application of BIM and the construction process of smart cities. The conversion between BIM and GIS 3D models inevitably leads to information loss. The tolerance for information loss during BIM conversion varies among different applications. At present, there is no research report on the measurement method of geometric information loss in the process of BIM and GIS model conversion in academia and industry. This article takes the conversion of BIM models under IFC standards and GIS 3D models under GML standards as an example, proposes three measurement methods for geometric information loss during the model conversion process under two standards, and comprehensively evaluates them. The research results provide effective data conversion quality reference standards for BIM applications, smart city construction, and refined management.
