Pedestrian dead reckoning uses inertial sensors carried by pedestrians to track their positions, wherein step detection and step length estimation play the key roles. Compared with pioneer researches using body-mounted sensors, smartphone-based dead reckoning has more flexibility but raises more challenges. To reduce the negative influence of sensor noise and varying walking speed, the paper proposes...
