A:
Vehicle light curtains are used to classify vehicles at highway toll stations, mainly in the following ways:
Multi-beam detection
Light curtains are arranged on both sides of the lane to form multiple detection areas, which can accurately detect parameters such as the number of wheels, wheelbase, and vehicle height.
Real-time data analysis
The system records the time difference and occlusion pattern of the vehicle passing through each beam, and determines the vehicle length, vehicle height, number of axles, etc.
Classification algorithm processing
The collected data is input into the classification algorithm and matched with the preset vehicle model standards to complete the classification of small cars, trucks, buses and other models.
Linkage with the toll system
The classification results are directly transmitted to the toll system, and the corresponding toll standards are automatically matched to improve efficiency and accuracy.
This method has the advantages of non-contact, high speed, and high accuracy, and is particularly suitable for unmanned and intelligent high-speed toll environments.
