Method and device for license plate recognition and classification

Abstract

Embodiments of the present invention provide a method and device for license plate recognition and classification. The method includes: determining a plurality of image samples of the image to be recognized based on the image to be recognized; Recognizing the image samples to be recognized to obtain a first recognition result; based on at least two different image processing methods, respectively processing at least two image samples to be recognized; using a first predetermined license plate recognition algorithm to recognize the plurality of images respectively Carry out license plate recognition on samples; determine the first number of the first recognition results consistent with the first license plate recognition results, and determine the proportion of the first number in the total number of first license plate recognition results; if When the first recognition ratio is greater than a predetermined first ratio threshold, it is determined that the license plate information in the image to be recognized is the first recognition result. Through the present invention, the accuracy rate of the license plate recognition result is greatly improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for recognizing and classifying license plates. Background technique [0002] With the substantial increase of the national economic level, people's living standards are also increasing day by day, and the car ownership in various regions has been growing steadily on the basis of a huge base. With the increase of the number of automobiles, the management workload and management difficulty of automobiles will increase thereupon, and for the management of the license plate number as the identity mark of the automobile, the recognition of the license plate is particularly important. [0003] The existing license plate recognition technology has been applied to various occasions such as highway toll collection, parking management, weighing system, traffic guidance, traffic law enforcement, highway inspection, vehicle dispatching, and vehicle detection. Based on...

AI Technical Summary

Problems solved by technology

The recognition rate of license plate recognition in the prior art is easily affected by factors such as time, light, weather, and plant occlusion, resulting in certain errors in the recognition results, which cannot provide high-accuracy recognition results, and even for some recognition results, still need to Perform background manual verification again, which increases operating costs and workload
