Abstract

The present invention discloses a real-time license plate detection and recognition method and device based on color augmentation, the method comprises: step: obtaining car images containing license plates as a license plate detection training set, inferring license plate detection results through the trained license plate detection model; step: performing view correction transformation on the detected license plates to obtain frontal view images of the license plates; step, using the obtained frontal view images of the license plates as a training set for license plate recognition, using a license plate recognition model based on deep neural network for license plate recognition to obtain license plate recognition results; step: displaying the license plate detection results and the license plate recognition results on the original test images or outputting them as needed, completing the detection and recognition of the license plates in the images.
