ABSTRACT:
A vehicle detection system is provided for detecting vehicles with high precision recognition with less misdetection and less electricity consumption, the installation of the vehicle detection system causing less damage to a town's aesthetic beauty. Vehicle detection is determined by processing an input level value provided from a sensor that detects infrared radiation irradiated from an object to be detected, and the vehicle presence judgment is carried out by calculating a background level value based on an input level value detected from infrared radiation during “absence of a vehicle”, and by comparing the value based on a difference between the input level value (comparative value) by a data processing unit. By using the sensor that passively detects infrared radiation, the system consumes less electricity, and maintains its accuracy of detection even if detection is performed sideways of vehicles.
