License plate character recognition method and device, and electronic equipment

Abstract

The embodiment of the invention provides a license plate character recognition method and a device, and electronic equipment. A license plate picture to be recognized is sent to a deep mutual learningnetwork composed of at least two convolutional neural networks, the convolutional neural networks are used for recognizing characters to be recognized in the license plate picture, and a preliminaryoutput result of the characters to be recognized is determined. And a final output result of the to-be-recognized character is obtained according to the preliminary output result of the to-be-recognized character. According to the method, the device and the electronic equipment, the extracted features are further optimized by combining the deep mutual learning network on the basis of extracting the features by utilizing at least two convolutional neural networks, so that the license plate character recognition accuracy is greatly improved, and the license plate character recognition capabilityis improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a license plate character recognition method, device and electronic equipment. Background technique [0002] Chinese character recognition in license plate character recognition is the last step of the license plate recognition system, and it is also a crucial step, which directly affects the accuracy and efficiency of the entire recognition system. Domestic license plates contain 7 or 8 characters. The first character of a common license plate is a Chinese character, and the other characters are mostly letters or numbers. [0003] License plate Chinese character recognition usually adopts four recognition methods, which are template-based matching method, neural network-based method, support vector machine-based method and the recent deep learning-based method. The first three methods are conventional recognition methods, which require manual selection of targe...
