Abstract

The invention is applicable to the technical field of license plate anti-counterfeiting, and provides a license plate anti-counterfeiting method based on a binocular camera. The method comprises the following steps of acquiring the feature information of a target license plate, wherein the feature information comprises the pixel width information and the parallax information corresponding to the target license plate; and inputting the feature information into a preset license plate anti-counterfeiting support vector machine model for processing to obtain an anti-counterfeiting result of the target license plate and the result confidence information of the anti-counterfeiting result. According to the scheme, a measurement problem based on the license plate width data is converted into a dichotomy problem based on a support vector machine model, the errors are reduced, and the license plate anti-counterfeiting accuracy is improved.

Description

technical field [0001] The present application belongs to the technical field of license plate anti-counterfeiting, and in particular relates to a method and device for license plate anti-counterfeiting based on a binocular camera. Background technique [0002] With the rapid development of computer vision technology and electronic equipment in recent years, the automatic license plate recognition system saves labor costs and makes people's travel and life more convenient. However, there have been cases of stealing other people's license plate images through mobile phones or other electronic devices to deceive the license plate recognition system. In the field of license plate recognition, it is no longer just the detection and recognition of license plates or the pursuit of higher recognition accuracy. False license plates are a new type of problem that needs to be solved urgently in the current license plate recognition field. In the existing license plate recognition met...
