Parking lot < ahref=“ http://www.fuyingkeji.com/ "> application principle of license plate recognition system < / a >

The parking lot license plate recognition system is composed of two modes: trigger and video stream to ensure the traffic rate of vehicles. Trigger technology refers to embedding ground sensing coils on the road surface, and the vehicles enter and exit through the ground sensing mode. The ground sensing line gives the signal to the gate, and the gate is lifted to release, so as to maintain the traffic efficiency; Video streaming refers to the technology that selects a better recognition area in the background of the system, sets up the monitoring area, and the system detects the vehicles in the monitored area when the vehicles enter and exit, and automatically extracts the vehicle license plate information for processing

License plate recognition technology is an important part of modern intelligent transportation system, which is widely used. Based on digital image processing, pattern recognition, computer vision and other technologies, it analyzes the vehicle image or video sequence taken by the camera to obtain the license plate number of each vehicle, so as to complete the recognition process
