Surveys show that the license plate recognition of parking lots is increasingly favored by car owners and car park operators. Their highly efficient and intelligent functions enable vehicles to pass quickly, avoid road congestion during peak periods, and queue users; the use of license plate numbers as an entry and exit vouchers improves Vehicles are parked safely to solve the charges loopholes; card management work is eliminated, eliminating the user from forgetting to bring the card. So there are so many functions in the parking license plate recognition system. What part of it is there?
The license plate recognition system parking lot is basically the same as that of the original parking lot system. Smart gate, gate control machine (ticket box), floor coil, vehicle detector, electronic display screen, guard post, surveillance camera, parking lot management computer . The biggest difference is in video recognition and card exemption. This requires the parking surveillance cameras and barrier control machines to have higher functional requirements. Below Dow will introduce the core components that complete the license plate recognition.
1. Surveillance cameras. The contrast between the surveillance camera and the parking lot is quite different from that of the general image contrast camera. It is a special license plate recognition camera for parking lots. It uses high-speed DSP embedded intelligent hardware, embedded identification software, and completes video capture. Image processing, license plate inspection, license plate segmentation, character recognition, tracking and contrast, image compression, data transmission, and other complex computer image processing technologies, system recognition speed, high reliability, the device can be carried on the two-way video input license plate Recognition, according to different engineering application scenarios, two-way video can be selected as front or rear mode recognition, without affecting each other.
2. The license plate recognition of the fill light has very high requirements for the on-site environment of the parking lot. It is inevitable that there will be insufficient light. Filling the light can ensure that the license plate can recognize the camera enough light to successfully capture the license plate.
