The survey shows that the license plate recognition of parking lots is increasingly favored by car owners and parking lot operators. Its efficient and intelligent function can make vehicles pass quickly, avoid peak road congestion, and users queue in line; use the license plate number as the entry and exit certificate The parking of vehicles is safe, and the loopholes in toll collection are solved; the card management work is eliminated, and the problem of users forgetting to bring cards is avoided. So the parking lot license plate recognition system has so many functions, what are its components?
The parking lot of the license plate recognition system is basically the same in the internal parking lot system. The intelligent barrier, ticket dispenser machine, senser coil, the vehicle detector, the electronic display, the guard booth, the surveillance camera and the parking management computer . The biggest difference is that the video recognition and card exemption are required, which requires the parking lot surveillance camera and the barrier control machine to have higher functional requirements. Next, Doyle will introduce the core components to complete the license plate recognition.
1. Surveillance camera, there is a big difference between the surveillance camera and the general image contrast camera function of the parking lot. It is a special license plate recognition camera for the parking lot. It uses high-speed DSP embedded intelligent hardware and embedded recognition software to complete video acquisition Image preprocessing, license plate detection, license plate segmentation, character recognition, tracking comparison, image compression, data transmission and other complex computer image processing technologies, the system has fast recognition speed and high reliability, and the device can separately license plates for the two input videos Recognition, according to different engineering application scenarios, the two channels of video can be selected as the front or rear mode recognition, without affecting each other.
2. Fill-in light license plate recognition has very high requirements on the on-site environment of the parking lot, and there will inevitably be insufficient light. The fill-in light can ensure that the license plate recognition camera has enough light to successfully capture the license plate.
Of course, the license plate recognition system is based on the on-site parking lot environment and requirements to cooperate with the parking lot system to complete the user's actual solution. Welcome to contact with us get more about COMA parking solution. www.coma-carparking.com
