Abstract

The invention discloses a multi-vehicle-license-plate dynamic identification method of a real-time traffic scene. The method is mainly divided into the multiple main steps of image pre-processing, vehicle-license-plate locating network training, image post-processing, identification network training and the like. Multiple pieces of vehicle-license-plate information in a single picture can be highly efficient identified in real time by using a vehicle-license-plate locating network and a character identification network in a case of not dividing character information; and compared with traditional character segmentation and identification methods, the method of the invention has innovative advantages, and can be widely applied to parking lot charging and peccancy behavior monitoring of expressways and the like.

Description

technical field [0001] The invention relates to the technical field of machine vision and image processing, in particular to a method for dynamic recognition of multiple license plates in real-time traffic scenes. Background technique [0002] In recent years, with the rapid development of the field of intelligent transportation, the research on automatic license plate recognition algorithm has attracted more and more attention. Automated, fast, accurate and powerful license plate recognition system has become the demand of traffic control and traffic law enforcement. [0003] The traditional license plate recognition method is mainly divided into three steps: license plate area positioning, license plate character segmentation, and character recognition, all of which are based on a single license plate in a single image. Prior art CN107220638A discloses a license plate detection and recognition method based on deep learning convolutional neural network. Its main contents i...
