Abstract :
In this paper, we propose a novel model of stride length estimation for pedestrian dead reckoning (PDR) that allows a PDR system to switch its estimation method according to whether the pedestrian is walking or running. Then, we study the application of the mode switching to a PDR/GPS/map-matching integrated positioning system for mobile phones. The experimental results show that this mode switching makes stride length estimation more adaptive, and improves the total accuracy of positioning.
