License plate recognition method, server and parking management system

Abstract

The invention relates to the field of parking management, in particular to a license plate recognition method, a server and a parking management system, and the method comprises the steps: obtaining afirst license plate number, recognized by an electronic license plate recognition device, of a vehicle, and setting an electronic license plate on each vehicle; acquiring a second license plate number of the vehicle identified by the license plate image recognition device; determining whether the first license plate number is the same as the second license plate number; and if not, determining that the vehicle is a fake-licensed vehicle, and replacing ETC equipment by an electronic license plate arranged on the vehicle in combination with a license plate image recognition device of the parking lot, so that the fake-licensed vehicle phenomenon caused by use of ETC is prevented. An electronic license plate recognition device and a license plate image recognition device are combined to jointly recognize the license plate number of the same vehicle. Whether the vehicle is a fake-licensed vehicle or not is judged by judging whether the two vehicles are the same or not, if yes, timing charging of the vehicle is normally conducted, and if not, it is indicated that the vehicle is the fake-licensed vehicle, and therefore the fake-licensed vehicle phenomenon caused by ETC is prevented.

Problems solved by technology

However, there is the problem of false use of vehicles, that is, false cards. For example, the OBU of vehicle A is set on vehicle C, and vehicle A is a monthly subscription or VIP customer of the parking lot. When vehicle C passes through the ETC device, it will directly perform timing and deduction according to vehicle A. etc. This method is not conducive to the management of vehicles in the parking lot
