基于北斗和蓝牙的室内外协同定位系统
Indoor and outdoor collaborative positioning system based on Beidou and Bluetooth
摘要
Abstract
At present,a single positioning technology cannot achieve good positioning results both indoors and outdoors simultaneously.For example,Beidou positioning technology can achieve high accuracy in outdoor positioning,but its performance in indoor positioning is poor.Bluetooth has high positioning accuracy in indoor positioning but is less effetive in outdoor positioning.Based on the above situa-tion,this paper proposes an indoor and outdoor collaborative positioning technology based on Beidou and Bluetooth positioning.The Bei-dou and Bluetooth positioning systems are unified in the same coordinate system,and an improved BP neural network is used to achieve seamless switching in all scenarios.At the same time,a positioning fusion strategy is introduced for indoor and outdoor buffer areas to improve positioning accuracy.The experiment results show that in all scenarios,the average positioning error of the collaborative posi-tioning system has increased by 0.7％,31.7％and 2.4％compared to a single positioning system,respectively,proving the effective-ness and accuracy of the method.关键词
