Modeling of graph-based semantic spatial model for indoor navigation

LIN Diao;SONG Guo-ming;Deng Chen;Zhengzhou Institute of Surveying and Mapping;  
Indoor spatial model is the key to indoor navigation,most of which have limited applicability because only parts of factors related to navigation in modeling are concerned.According to the characteristics of indoor space,and the user behavior,geometric and semantic information expression,path planning efficiency,agraph-based semantic spatial model for indoor navigation is proposed to solve the problem.Firstly a conceptual indoor navigation model is built based on graph theory;secondly on the basis of the conceptual model,specific geometric graph modeling method and the way of semantic expression are proposed;then node and edge data structures are designed;finally the specific processes for path planning based on the model in different contexts is studied.It is of instructive significance to build context-aware indoor navigation model based on the proposed model.
