Abstract
Indoor positioning services have been widely used in various fields such as navigation,rescue and disaster relief.Indoor positioning methods based on Bluetooth sensors can be realized by some built-in functions of mobile phones,so they are easy to popularize and practical,but they often perform poorly in crowded areas and complex electromagnetic environments.To address this issue,a fingerprint indoor positioning method fusing Bluetooth and geomagnetism is proposed.Firstly,a number of Bluetooth beacons are set up in the shopping mall to be positioned,and the iBeacon function and Hall sensor of mobile phones are utilized to receive Bluetooth and geomagnetic signals respectively.Then,the Bluetooth estimated coordinates and the geomagnetism estimated coordinates are fused at the decision-making level to calculate the user position,which not only reduces the positioning error but also avoids the additional hardware resource consumption.The experimental results show that the proposed method significantly improves positioning accuracy.关键词
