In order to study the application of computer graphics technology in license plate recognition system, the image pixel feature representation in computer graphics technology and image denoising technology are applied to license plate recognition, which is convenient for license plate image processing in license plate recognition system. The basic principles of the system, image edge detection preprocessing, license plate image feature expression and license plate image denoising combined to improve the accuracy of night license plate recognition, can provide technical support for night detection of license plate recognition system.
