摘要
室内地图是室内位置服务的重要基础。针对传统室内地图数据更新效率低、完备性差等问题,研究了室内地图的要素特征,探讨了众包模式下数据更新的关键问题。在此基础上,设计并实现了室内地图数据获取与更新系统,实例验证,可有效地提高室内地图数据的现势性与完备性,为室内地图维护提供了新的思路。
Indoor map is an important foundation of indoor location services.In order to update indoor map efficiently and keep its data completely,this paper focuses on the characteristics of indoor map elements,and applies crowdsourcing technologies to support map updating.A prototype system for collecting and updating indoor map data is designed and implemented and test cases can successfully demonstrate the feasibility of our method,which provides a new idea of maintaining indoor map.
