室内导航是当前空间信息应用领域的一个热点问题,针对室内空间和室内导航应用需求的特点,提出了一种基于语义的室内空间导航模型。该模型以图论模型为理论基础进行空间的几何抽象和拓扑构建,在准确描述大型建筑室内拓扑关系的基础上,添加模型要素的属性信息以及属性与环境信息的语义关联约束,使模型可以根据出行者的具体需求或环境的变化,改变模型的属性信息,为精细化的导航服务提供基础。
Abstract：According to the characteristics of interior space and the requirements of indoor navigation, a semantic spatial model for indoor routing was proposed in this paper. This model was built based on graph theory for geometric abstraction and topological construction. Attribute information and structures of nodes and edges were also added to the model in order to describe the connectivity of different positions in complex indoor environments precisely. For the precise and user-adaptive indoor navigation, a series of semantic constraints were also proposed, whose attributes are associated with indoor environments.
