Abstract

This application is applicable to the technical field of license plate anti-counterfeiting, and provides a method for license plate anti-counterfeiting based on a binocular camera, including: acquiring characteristic information of a target license plate; the characteristic information includes pixel width information and parallax information corresponding to the target license plate; The feature information is input into a preset license plate anti-counterfeiting support vector machine model for processing, and the anti-counterfeiting result of the target license plate and its result confidence information are obtained. The above solution converts the measurement problem based on the license plate width data into a binary classification problem based on the support vector machine model, reduces errors, and improves the accuracy of license plate anti-counterfeiting.

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...
