摘　　要：传统的室内空间信息模型或者过于复杂导致操作性较差,或者没有充分表达地图匹配所需的空间要素信息,阻碍地图匹配方法的高效实施。该研究将以构建能够有效支撑地图匹配的室内空间信息模型作为研究目标,此模型应明确室内空间要素的表达内容,并应确定具体的表达方法。模型的构建应以地图匹配方法的机理为基础,以室内地图匹配的实际需要为导向,以表达支撑室内地图匹配的空间信息为目的,分别对室内空间要素的位置及属性,室内空间要素之间的拓扑关系进行表达。该研究构建面向地图匹配的室内位置-语义模型。实验表明此模型较为简洁且信息完备,可在保证地图匹配实际需要的同时提高运行效率。The traditional indoor spatial information model is either too complex to operate poorly,or does not fully express the spatial element information needed for map matching,which hinders the efficient implementation of the map matching method.This study will take the construction of an indoor spatial information model which can effectively support map matching as the research goal.This model should clarify the expression content of indoor space elements and determine the specific expression methods.The construction of the model should be based on the mechanism of map matching method,guided by the actual needs of indoor map matching,and for the purpose of expressing the spatial information supporting indoor map matching,respectively on the location and attributes of indoor space elements.The topological relationship between indoor space elements should be expressed separately.In this study,an indoor location-semantic model for map matching is constructed.The experimental results show that the model is simple and complete,which can ensure the actual needs of map matching and improve the operation efficiency at the same time.
