要約(英語): Pedestrian Dead Reckoning (PDR) is used as a method to estimate pedestrian's positions when the satellite positioning is not available. Previous studies on PDR used experimentally determined parameters and models. In this paper, in order to avoid the use of experimentally determined parameters and models, we propose a method to construct a PDR system suitable for pedestrians individually by utilizing the satellite positioning data effectively. PDR generally requires three steps: walking detection, step length estimation, and heading angle estimation. The proposed method constructs a walking false detection prevention system and estimates the average step length when the satellite positioning is available. Once the satellite positioning becomes unavailable, the PDR system adaptively constructed for the individual pedestrian starts to work. From experimental results, we can see that the proposed method works well and can provide accurate positioning results even when the satellite positioning is not available.
