基于Wi-Fi/PDR的室内融合定位算法研究
Research on Indoor Fusion Positioning Algorithm Based on Wi-Fi/PDR
摘要
Abstract
With the maturation of outdoor positioning systems,the demand for indoor positioning has gradually increased.However,facing the complex indoor positioning environments,no single indoor positioning technology can achieve high-precision positioning.Wi-Fi and Pedestrian Dead Reckoning(PDR)positioning technologies are commonly used indoor positioning technologies.And PDR suffers from cumulative errors and poor stability,making it unsuitable for long-term standalone use,while Wi-Fi positioning technology is easily affected by the complex indoor environments.To reduce the errors associated with PDR and Wi-Fi positioning technologies and obtain more precise positioning results,this paper proposes two fusion algorithms of a weighted fusion positioning algorithm and a fusion positioning algorithm based on the Extended Kalman Filter(EKF).The fusion algorithms reduce the impact of cumulative errors on PDR positioning results while improving the precision of Wi-Fi positioning.Experimental results show that the proposed algorithm in this paper offers better positioning precision and stability compared to standalone positioning technology and the weighted fusion positioning algorithm.关键词
