Abstract

The invention discloses a license plate recognition system based on an artificial neural network. The license plate recognition system comprises an image sensor, a video encoder, a video decoder and a touch liquid crystal display, and is characterized by further comprising a digital signal processor, wherein the model of the digital signal processor is TMS320DM642; the image sensor is connected with the video decoder; the video encoder is connected with the digital signal processor; the digital signal processor is connected with the video decoder; the video decoder and the digital signal processor are connected with a communication interface module. The license plate recognition system is high in running speed, high in recognition precision, simple, and high in robustness, and can accurately recognize various license plates with hazier ground colors under poor illumination conditions.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a license plate recognition system and method based on an artificial neural network. Background technique [0002] With the rapid development of my country's economy and the continuous improvement of people's living standards, there are more and more private vehicles, and the demand for transportation is also increasing. The speed of existing transportation infrastructure construction is far behind motor vehicles and other means of transportation. growth rate. The traditional manual management method has been increasingly unable to meet the needs of actual work. How to monitor vehicles safely, reliably and quickly, and provide human beings with a simple, stylish and safe modern life brought by high technology, has become a new topic. In this context, the concept of intelligent transportation has ushered in development opportunities. [0003] The prospect of intelligent...
