摘　　要：全球导航卫星系统提供的位置服务在室外已得到广泛应用,如今人们也希望能够在室内空间获取类似的位置服务,而面向室内空间的定位技术尚在研究中。分析室内空间的特殊性及复杂性,总结面向室内定位的3D建筑模型的特征,介绍现有的室内3D建筑建模的方法和存在的问题,在此基础上提出一种面向室内定位的3D建筑模型的构建方法。实验证明该方法是一种经济、高效、实用的室内3D建筑建模方法,可广泛应用在小范围的建筑物、地下洞室、隧道等空间内的3D建筑模型构建及相关研究中。Positioning services provided by the global navigation satellite system has been widely used in outdoor, currently people also wish to get similar positioning services in indoor space. But the positioning technology for indoor space is still on studying. In this paper, we analyse the particularity and complexity of indoor space, summarise the characteristics of 3D building model for indoor positioning, and intro- duce existing indoor 3D building modelling methods and the problems. On this basis we propose an indoor positioning-oriented construction method for 3D building model, at last we prove through experiments that this method is an economical, efficient and practical indoor 3D build- ing modelling method. The method can be widely applied to 3D building model construction for small-size spaces of buildings, underground caves or tunnels, etc. , and to the related study as well.
