APPLICABILITY VERIFICATION OF MAGNETIC MAPS FOR INDOOR PEDESTRIANS LOCALIZATION SYSTEM

In this study, we focused on a common issue that indoor positioning systems face: adapting to changes in pre-established environments. We investigated the use of residual magnetism, which exhibits minimal changes over time, as a basis for creating magnetic field maps. We identified specific processes under construction where the magnetic field stabilizes, allowing for the creation of effective maps. To verify positioning accuracy, we implemented a positioning system that integrates magnetic field maps with pedestrian dead reckoning using a particle filter, achieving the target accuracy. Our results also demonstrate that this system can be effectively applied in similar environments.
