The survey shows that the license plate recognition of parking lots is more and more favored by car owners and parking lot operators. Its efficient and intelligent functions can enable vehicles to pass quickly and avoid users waiting in line at entrances and exits during peak hours; use license plate numbers as entry and exit certificates to improve The vehicle is parked safely and the charging loopholes are solved; the work of card management is eliminated, and the problem of users forgetting to bring the card is eliminated. So the parking lot license plate recognition system has so many functions, what are its components?
License plate recognition system. The parking lot is basically the same as the original parking lot system. It is composed of intelligent barriers, barriers control machines (ticket machine), ground sensing coils, vehicle detectors, electronic displays, guard booth, surveillance cameras and parking lot management computers. This requires monitoring cameras and barrier control machines in parking lots with higher functional requirements. Next, COMA will introduce the core equipment for license plate recognition.
1. Surveillance camera. The surveillance camera here is very different from the general image comparison camera function of the parking lot. It is a special license plate recognition camera for the parking lot, which completes video capture, image preprocessing, license plate detection, license plate segmentation, and character recognition. , Tracking and comparison, image compression, data transmission and other complex computer image processing technology, the system recognition speed is fast, the reliability is high, the equipment can separately recognize the license plate of the two input videos.
2. Supplementary light. License plate recognition has very high requirements on the on-site environment of the parking lot. It is inevitable that there will be insufficient light. The supplementary light can ensure that the license plate recognition camera has enough light to successfully capture the license plate.
