Research on Geomagnetic Matching Localization for Pedestrian

Nowadays, geomagnetic localization has become a new locating method for pedestrian. In this paper, geomagnetic matching localization method is proposed, the result of localization is based on the correlation between the measured geomagnetic data and the known base. In the flat terrain, pedestrian dead reckoning (PDR) is used to obtain mileage accumulation information to assist the geomagnetic matching locating, while in the rough terrain like elevators, stairways, etc., where PDR cannot provide reliable mileage information, the dynamic time warping (DTW) algorithm is used to warp the measured geomagnetic data and the known base. The experimental results show that the proposed method can provide the results of locating reliably and continuously and meet the demands of pedestrian localization.
