A Parking Space Detection Algorithm Based on Magnetic Sensors

摘要

Magnetic detector is a new type of vehicle detection equipment. A new roadside parking space detection algorithm is proposed based on AMR sensors in this paper. It uses state machine mechanism and overcomes the limitation of existing threshold-based algorithm. The current status is identified via processing two types of magnetic data. Combined with state-related parameters, it can achieve an accurate detection of the parking space status in different scenarios and parking modes. The experiment results show that the accuracy can reach 95%.
