Method for printing codes on license plate and sprayed codes in vehicle sticker and computer equipment

Abstract

The invention provides a method for printing a license plate and a sprayed code in a vehicle sticker, a computer readable storage medium and computer equipment. The method comprises the following steps: acquiring a picture containing the vehicle sticker; obtaining position information of a license plate and a sprayed code from the picture containing the vehicle sticker according to a differential binarization algorithm, and outputting a picture for marking the position information of the license plate and the sprayed code; obtaining the position information of the license plate and the sprayed code from the picture marked with the position information of the license plate and the sprayed code according to a regression algorithm, and outputting the picture marked with the position information of the license plate and the sprayed code after the regression algorithm; and deleting the overlapped position information of the license plate and the sprayed code from the picture marked with the position information of the license plate and the sprayed code after the regression algorithm to obtain a final picture marked with the position information of the license plate and the sprayed code. And printing all license plates and sprayed codes in the picture for marking the final position information of the license plates and the sprayed codes. And a license plate and a sprayed code of a small target can be printed.

Description

technical field [0001] The application belongs to the field of image processing, and in particular relates to a method for coding license plates and inkjet codes in car stickers, a computer-readable storage medium and computer equipment. Background technique [0002] Since the company is vigorously promoting the car sticker service in various cities, the quality requirements for the stickers are relatively high. The company conducts random checks on the stickers by city every day to check the quality of the stickers, which is also directly linked to the performance of the city. In order to ensure the fairness of the review, a third-party company is introduced to conduct quality inspection; after the introduction of third-party quality inspection, data security is involved. In order to ensure the safety of driver information on our company platform and the fairness of reviewers, it is necessary to code key information on the provided image data. However, at present, it is ma...
