基于二维码和A*算法的室内精准定位导航系统

摘要

随着移动互联网的迅猛发展，基于位置的服务LBS（Location Based Services）在现代人的生活中起着至关重要的作用。由于室内环境无法精确获取GPS数据，导致室内定位的需求一直得不到满足。在历时一个月调研了各阶层有代表性的智能手机用户的前提下，此文提出了基于二维码的室内精准定位技术，以及基于A*算法的室内语音导航技术。利用AutoCAD、PhotoShop和3DMax等软件设计室内平面图，并在当前流行的Android智能手机平台下，设计开发了基于二维码和A*算法的室内定位系统。实际应用表明，该系统具有精准定位、人性导航和丰富信息的三大基础功能，能够满足人们日常在大型公共建筑中的基本需求。%With the rapid development of mobile Internet, the Location-Based Services(LBS) play a vital role in modern life. Due to unable to accept the GPS data in the indoor environment, the indoor location technology has been unable to meet demand. This paper put forward the indoor precise location technology based on two-dimensional code and the indoor voice navigation technology based on A* algorithm, after investigating all levels of representative smart phone users for a whole month. This paper designed interior plan through the AutoCAD, PhotoShop and 3DMax. And based on the Android mobile phone system which is popular all over the world, this paper designed and developed the indoor precise location and navigation system based on two-dimensional code and A* algorithm. The practical applications show that with three basic functions of precise location, user-friendly navigation and a wealth of information, this system can satisfy the basic requirements in the large public buildings in daily life.
