A Novel Vehicle Detection Method Based on Geomagnetism and UWB Ranging
Abstrak
With the increasing number of private vehicles, intelligent parking space management systems (IPSMS) are widely used to analyze the parking spaces status information and to improve parking efficiency. The wireless vehicle detectors (WVD) based on the magnetic sensor have been widely used in IPSMS to collect the information of parking spaces. However, due to the existence of magnetic signal blind zone between the front and rear wheels of high-chassis vehicles, the accuracy of the single magnetic sensor based detector decreases markedly in detecting high-chassis vehicles such as SUVs, MPVs, Pickups, etc. In order to improve the performance of WVDs, this paper proposes a vehicle detection method based on the fusion of the Ultra- Wideband (UWB) ranging measurements and magnetic signals to improve the vehicle detection accuracy. We have designed several WVD prototypes based on our method and deployed them in the actual parking spaces to verify and evaluate the performance of our proposed algorithm. The experimental results show that the vehicle detection accuracy of our proposed method is about 8.4% higher than that of the conventional single magnetic sensor based method.
