Abstract

The invention discloses a license plate identification method. The method comprises that a type of a license plate is determined, and according to the type of the license plate, a corresponding license plate identification scheme is selected; and the license plate is identified according to the selected license plate identification scheme. The type of the license plate is determined by determiningthe type of the license plate according to light information of reflected light of the license plate; or determining the type of the license plate according to the length-width ratio of the license plate. The license plate identification scheme is a scheme for the traditional or new-energy license plate. License plate identification comprises license plate cutting, character identification and character combination. Via the method, identification for the new-energy license plate is integrated into present license plate identification technologies, both traditional and new-energy license plates are discriminated and identified automatically, the method is simple, the computational complexity is low, an identification result is highly accurate, the intelligent effect is good, and the practical value is extremely high.

Description

technical field [0001] The invention relates to the field of license plate recognition, in particular to a license plate recognition method. Background technique [0002] With the substantial increase in the level of the national economy, people's living standards are also increasing. On the one hand, it is obvious that the number of cars in various regions is growing steadily on the basis of a huge base. [0003] With the increase of the number of cars, the management workload and management difficulty of the cars will increase accordingly, and new requirements will be put forward for the management of the license plate number as the identity mark of the car. Among them, the most common one is Recognition of license plates. [0004] In my country, for traditional fossil fuel vehicles, license plates with 7-digit numbers are used, and uniform regulations have been made on the size, distribution, and characters of license plates. In the prior art, multiple recognition schem...
