A new method to enhance Wi-Fi based indoor Pedestrian Dead Reckoning (PDR) in corridors by fusing uncalibrated security cameras is proposed in this paper. An algorithm using uncalibrated security cameras to infer a user's heading in corridors is developed. Android devices and a security camera system are used to build up an experimental platform for field data collection and algorithm development/assessment...
New location algorithms using Wi-Fi or/and magnetometer sensors are proposed considering the orientation impact on the measurements. The feasibility of magnetometer alone fingerprint positioning and orientation inference is also assessed with real indoor data. Android smart devices with low cost sensors are used to build up database along with a Gaussian Processes Regression (GPR) model and to collect...
