摘要
商业中心、交通枢纽、医院、停车场等复杂室内及地下空间的安全管理与应急响应对室内外无缝导航与位置服务的需求日益迫切,提出了一种室内位置信息模型,扩展了OGC标准CityGML和IndoorGML中的位置信息描述,提供了描述室内相对位置和室内绝对位置的本体,介绍了一种针对三维建筑物模型的室内空间自动提取方法,为智能位置服务奠定了重要基础。
The seamless indoor and outdoor navigation and location-based services for the safety management and emergency response of shopping centers, hospitals, dirporls, subways and other underground complex interior space are increasingly urgent, this article proposed an indoor location information model which extends the location deseriptions of OGC standardsCityGML and IndoorGML, provides the ontology of relative and absolute indoor locations and lays an important foundation for in- telligent location-based services with presenting an automated indoor space extraction of complex 3D building models.
