基于室内外定位的校园LBS系统设计与实现

摘要

This study addresses the dislocation of the current application software of the intelligent mobile phone location based service( Location Based Service,LBS) ,a design solution of campus LBS system is introduced based on indoor-outdoor positioning. First,the architecture of the system is introduced. Then the key technologies such as Mobile GIS,GPS and the RSSI fingerprint positioning strategy in system design are analyzed elaborately. At last the function modules of system are tested and verified. Test results show that the system can realize some functions of terminal positioning,service based on indoor positioning,campus navigation,map service and so on. It occupies fea-tures of convenience,feasibility and practicality.%为了解决目前智能手机中位置服务LBS( Location Based Service)类移动应用在小环境区域不能准确提供位置服务的问题，以校园为例提出了一种基于室内外定位的LBS系统设计方案。首先介绍系统结构设计，然后详细分析了Mobile GIS、GPS、基于WiFi信号强度值的位置指纹定位算法等系统设计中的关键技术，最后测试验证系统的各个功能模块。测试结果表明，系统可以实现终端定位、室内位置服务、校园导航、地图服务等功能，且操作便捷，具备可行性和实用性。
