Embodiment Construction

[0053] The application will be described in further detail below in conjunction with the accompanying drawings.

[0054] Trucks and trailers are prone to sticky stains due to irregular suspension of license plates, which can lead to difficulties in identification, violations of regulations or traffic accidents. Witnesses cannot see the license plate at the first time, so the license plate must be enlarged. Heavy-duty and medium-duty trucks and their trailer bodies or compartments should be sprayed with enlarged license plate numbers, and the words should be correct and clear. And for vehicles that are prone to traffic violations such as running red lights, speeding, and throwing drips, vehicles with muck vehicles must be equipped with enlarged license plates to facilitate identification, clarity and management, and reduce threats to the safe travel of the masses. The recognition of the enlarged license plate is helpful for traffic electronic eyes to identify large vehicles suc...

Abstract

The invention discloses an amplified license plate batch generation method and system, a storage medium and equipment, and the method comprises the steps: obtaining a license plate recognition image; acquiring a character image forming an amplified license plate based on the license plate recognition image; based on the obtained character images, combining the character images to generate a plurality of amplified license plate images; based on the generated amplified number license plate image, performing fuzzy processing on the amplified number license plate image to obtain a fuzzy processed license plate image, and storing the fuzzy processed license plate image in a database. According to the scheme, image processing can be performed on the amplified number license plate image, batch amplified number license plate images are generated, the sample size of the amplified number license plate is increased, and the identification rate of the amplified license plate can be improved.

Description

technical field [0001] The present application relates to the field of license plate recognition, in particular to a method, system, storage medium and equipment for batch generation of enlarged license plates. Background technique [0002] For enlarged license plates, there is no fixed background, and the aspect ratio changes greatly. For some painted enlarged license plates, when arranging, the spacing between characters is not uniform, and the fonts are not the same. If the recognition When the license plate recognition technology of blue plate is applied to the license plate recognition of the enlarged number, there will be problems of low recognition rate and weak model generalization ability. [0003] For the recognition of enlarged license plates, the biggest problem is the insufficient number of samples. For large vehicles such as trailers, trucks, and muck trucks, the number is relatively small in each city, and between different models, the enlarged number There a...
