Abstract

The invention discloses a license plate recognition method, device and system. The license plate recognition method comprises the steps that an image to be detected and the target detection recognition model based on a convolution neural network are acquired; license plate recognition is carried out on the image to be detected through the target detection recognition model based on the convolution neural network; and license plate information in the image to be detected is acquired, wherein the license plate information comprises the content of a license plate character group and the coordinate position of each character in the license plate character group. According to the technical scheme provided by the invention, the overall recognition of license plate characters is realized through the target detection recognition model based on the convolution neural network, which greatly reduces the processing difficulty of license plate recognition.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a license plate recognition method, device and system. Background technique [0002] With the continuous improvement of economic level and people's living standards, vehicles in large, medium and small cities are constantly increasing. At the same time, the ensuing traffic problems have attracted more and more attention. In the process of identifying traffic violations, the automatic and accurate identification of illegal vehicle license plates is particularly important. At present, the algorithm of license plate recognition usually adopts the algorithm based on convolutional neural network. Among them, the fast area convolutional neural network algorithm is one of the most advanced deep learning neural networks for object detection. The fast area convolutional neural network is composed of two parts of the network; one part is used to generate the area where the tar...
