摘要
室外环境下的全球卫星定位系统已经取得了很大的成功,但是室内环境较为复杂,全球卫星定位系统不能准确的定位室内的位置。所以研究室内环境的定位技术成为当下国内和国外的热点。基于可见光通信的室内定位技术成本较低,定位准确定高。文章研究了一种基于图像匹配、到达角度AOA和接收信号强度RSS的VLC混合定位技术,这种定位方法包括离线和在线两个阶段,结合尺度不变特征变换和指纹定位算法,能够提高可见光室内定位技术的准确性和实时性,提高定位技术的性能。
GPS in outdoor environment has achieved great success,but the indoor environment is more complex,GPS can’t accurately locate the indoor location.Therefore,the research of indoor environment positioning technology has become a hot spot at home and abroad.The cost of indoor positioning technology based on visible light communication is low,and the positioning accuracy is high.In this paper,a VLC hybrid location technology based on image matching,AOA and RSS is studied.This location method includes two stages:offline and online.Combined with scale invariant feature transformation and fingerprint location algorithm,it can improve the accuracy and real-time of visible light indoor location technology,and improve the performance of location technology.
