Principle of License Plate Recognition System - Tigerwong

The principle of the license plate recognition system is like this. Until the intelligent gate closes, the license plate recognition process is completed. Errors in each link will affect the owner's experience. There may be failure to open the smart gate, unsuccessful charging, failure to close the smart gate, etc. Therefore, the license plate recognition process is still a very rigorous process. Moreover, they are basically in contact with license plate recognition. Many friends know what license plate recognition is. However, few people know the operation principle of license plate recognition. Everyone only knows the surface principle, and few people know the deep-seated principle. Maybe many people only know the basic functions of the equipment, but do not know what the specific operation is to do, such as what role the system plays in it. What's different from my usual recognition? License plate recognition system is to summarize the principle of license plate recognition. The hardware includes camera, intelligent gateway, led voice intelligent screen and ground induction coil; Software is a set of license plate recognition parking lot system. The components of license plate recognition are nothing more than several hardware and a set of system. The combination of the two is a complete set of license plate recognition device. Generally, when the vehicle comes to the camera for license plate recognition, let's first understand the operation process. Then pass the lane slowly. At this time, you may find that you don't need to stop at all when you have passed the license plate recognition before. You can pass the lane unobstructed only at a slow speed. In addition to convenient storage, it can also facilitate the transmission of information, because when the vehicle passes, it has been recorded by the camera through the wide dynamic CMOS, and the optical image is transformed into an electrical signal through the front end. When the camera passes the calculation, the result is transmitted to the license plate recognition system; The license plate recognition system extracts relevant information from the huge license plate recognition database, transmits the information to the LED voice intelligent screen, and then transmits the door opening command to the intelligent gate. The intelligent gate opens automatically to allow vehicles to pass; When the vehicle drives to the ground induction coil behind the smart gate, the LED smart screen will play vehicle related information and fee deduction information. The ground induction coil will change the oscillation frequency under the influence of the vehicle, and then the coil will feed back this information to the system; The system sends a message to close the gate and transmits it to the intelligent gate; The intelligent gate closes the gate after receiving the information.
