室内位置服务是近年来国际位置服务领域的一个研究热点，室内空间模型则是实现室内位置服务的先决条件和关键所在。在对国内外大量文献进行分析研究的基础上，系统综述了面向位置服务的室内空间模型研究进展。首先，较之室外空间，从空间尺度、组成结构、空间约束3个角度分析了室内空间的独特性，并介绍了位置查询、导航、范围查询、最邻近查询和可视化5种主要的室内位置服务。然后，从建模原理、建模复杂度、适用性等方面对典型的室内空间模型如边界模型、格网模型、集合模型、图模型、语义模型进行了评述；最后，讨论了现有模型存在的主要问题，并对未来研究方向进行了展望。

In recent years,indoor location-based services (LBS)is a hot topic in the international location-based services research and indoor spatial model is the foundation and key of indoor LBS. Based on the analysis of a large number of domestic and international literatures, this paper reviewed the research progresses in spatial model for indoor location-based service. Firstly,compared to outdoor space the features of indoor space is analyzed,then position queries,navigation,range queries,nearest neighbor queries and visualization five major kinds of indoor location-based services are introduced. After that, existing indoor models such as boundary-based model,grid-based model,set-based model,graph-based model and semantic model are reviewed from the modeling principle,modeling efficiency,applicability,and other aspects. Finally,some research challenges and future directions are discussed.
