In this research, we propose an indoor positioning method using magnetic data. Magnetic data observed in the building tends to be stable for years and has location dependency. Proposed method utilizes magnetic data observed by pedestrians, and estimates pedestrian position. Using pedestrian magnetic data makes data collection easier and reduces position estimation cost. To estimate position correctly, we create magnetic data model. Magnetic data model is created by dividing routes into small cells. Each cell has magnetic average, magnetic standard deviation, connection and coordinates. Using particle filter, we estimate pedestrian position by comparing observed data and each cell of magnetic data model. We evaluate this method with HASC-IPSC and the result of prior experiment. The result shows that proposed method estimates pedestrian position with error within 10m under a specific condition, and confirms that the data collection cost is reduced larger than conventional Fingerprinting method.
