摘要
由于目前对室内导航的研究大都关注定位的问题,缺乏对地图建模的研究,使得导航不具备实际的地理场景,以及位置变更的实时反馈。针对这一问题研究了地图建模并将室内定位与之结合,真正实现室内导航应用。而在定位的问题上,室外采用北斗卫星导航定位系统,室内则利用WSN进行目标定位,定位结果使用安置在室内的信号中继节点进行组织和转发,就可以实现利用同一台北斗接收机完成室内外无缝定位。
The research on indoor navigation is mostly focus on positioning, paying no attention to the map modeling, which makes navigation do not have the actual geographical scene and real-time feedback of location change. To solve the problem, this paper makes use of map modeling in indoor positioning and makes the indoor navigation comes true. In order to achieve positioning, BeiDou satellite navigation and positioning system is made use of outdoor, and WSN is utilized indoor for targeting. The location is transmitted by signal forward node which is placement indoor, that there is no need to change the receiver for navigation with the same equipment.
