License Plate Recognition (LPR), short for license plate recognition, also known as license plate recognition or vehicle license recognition or vehicle license plate recognition, is an application of computer video image recognition technology in vehicle license plate recognition. That is, the license plate number is extracted and recognized from the image information.

The general principle of license plate number recognition is as follows: it is divided into four modules: image acquisition, license plate positioning, character segmentation, and character recognition, and then use software programming to realize each part, finally recognize the license plate, and output license plate number and other related information

Most of the traditional parking lots use the speed card method. The 1C card is distributed through the vehicles entering the parking lot, and the time of vehicle entry and exit is recorded as the main basis for billing. In order to enter and exit the parking lot, this method often causes traffic jams during the busy period of vehicle entry and exit. For example, a large-scale parking lot has a large daily traffic flow. The traditional parking lot management system cannot meet the needs of vehicles to enter and exit quickly. To solve the problem that vehicles cannot enter and exit at a high speed, Zento has introduced a new management concept, using license plate recognition technology to replace the traditional JC card technology, to solve the problem of traffic jams at the entrance and exit of the parking lot caused by the need to stop and swipe the card when the vehicle enters and exits, and to realize the vehicle without parking Extensive access management to solve the problem of congestion caused by excessive traffic flow.
