As we know, remembering where a car is parked in a large parking port is very difficult. Even with an indoor positioning system, if we don’t mark the car’s position previously, it can be hard to get back to the car. This paper presents a solution based on magnetic information matching and Pedestrian Dead Reckoning (PDR) to improve the situation. By recording the user’s moving trace with pedestrian dead reckoning and using magnetic information matching to find the right turning direction at the turning point, this paper brings up a new way to find the user’s car in a car park without using pre-deployed infrastructure or radio signals. The experiments show that the new solution can navigate the user back to the car successfully.
