Kurzfassung
In this paper we have presented an indoor positioning system for pedestrians combining Wireless LAN fingerprinting with foot mounted inertial and magnetometer sensors. To achieve a system capable of real-time processing we have employed a hierarchical Bayesian filtering approach using cascaded extended Kalman filters. The accuracy of the combined system was quantitatively evaluated in a real building against ground-truth. Our results show that accuracy is much higher than using Wireless LAN fingerprinting alone; in our experiment we achieved a positioning error (standard deviation) of roughly 1.6 meters. The approach requires only minimal fingerprinting effort since the high accuracy is achieved by the support of the inertial-based step estimation in the overall estimation process.
