First-stage license plate detection and recognition method based on deep learning

Abstract

The invention discloses a first-stage license plate detection and recognition method based on deep learning. The first-stage license plate detection and recognition method based on deep learning comprises the steps: S1, inputting a to-be-detected and recognized color image, and enabling the color image to be zoomed into an image with the size of 300 * 300 through an image preprocessor; s2, inputting the zoomed image into a detection module and a recognition module for license plate detection and license plate character recognition; and S3, regarding the output result of the combined detectionmodule and the recognition module as the license plate detection and recognition output result of the whole system. The beneficial effects of the invention are as follows: first-stage license plate detection and recognition system integrating license plate detection and license plate character recognition into one model has the main advantages that the advantages are as follows: according to the license plate detection and license plate character recognition algorithm based on deep learning provided by the invention, higher detection accuracy and character recognition accuracy can be kept in acomplex natural scene, so that the stability and the accuracy which exceed those of other related systems are shown.
