摘要
为解决游客游览溶洞景区时出现的迷路、失联等安全问题,设计了基于位置指纹和行人航位推算的溶洞内定位导航系统。该系统具备实时定位、基于溶洞地形线路导航、遇险救援等功能。文章给出了系统架构,定位导航的原理和方法,以及融合位置指纹和行人航位推算的互补滤波算法。经测试,该系统能够为游客提供精准且全面的位置服务,有助于提升景区的服务质量。
In order to solve the safety problems of tourists getting lost and losing contact when they visit karst caves, a positioning and navigation system in the karst cave based on location fingerprint and pedestrian dead reckoning is designed. The system has the functions of real-time positioning, route navigation based on the karst cave terrain, rescue in distress and so on. The system architecture, the principle and method of positioning and navigation, as well as the complementary filtering algorithm integrating position fingerprint and pedestrian dead reckoning are presented. Tests show that the system can provide accurate and comprehensive location service for tourists, and help improve the service quality of scenic spots.
