License plate identification system

Abstract

The invention discloses a license plate identification system. The system comprises a type discriminating module for determining the type of a license plate, a scheme confirmation module for selectinga corresponding license plate identification scheme according to the license plate type determined by the type discriminating module, and a license plate identification module for identifying the license plate according to the license plate identification scheme selected by the scheme confirmation module. The type discriminating module determines the type of the license plate by determining frequency information or frequency change information of reflected light for white light of the license plate or determining the length-width ratio of the license plate. The scheme confirmation module selects to implement identification according to traditional or new-energy license plate by determining the type. According to the selected scheme, the license plate identification module segments, identifies and combines a license plate image. Thus, 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, and the intelligent effect is good.

Description

technical field [0001] The invention relates to the field of license plate recognition, in particular to a license plate recognition system. Background technique [0002] With the substantial increase in the level of the national economy, people's living standards are also improving day by day. Obviously, on the one hand, the car ownership in various regions is steadily increasing on the basis of a huge base. [0003] With the increase in the number of cars, the management workload and difficulty of car management will increase, and new requirements have been put forward for the management of the license plate number as a car identification. Among them, the most common one is Recognition of license plates. [0004] In my country, for traditional fossil fuel vehicles, 7-digit license plates are used, and uniform regulations are made for the size, distribution, and characters of license plates. In the prior art, various recognition schemes have also been formulated for this ...
