The present invention relates to a network embedded multi-channel license plate detection system and a license plate detecting method, which is a system and method that can flexibly configure various detection parameters through networks to realize multi-channel and high-definition license plate detection. The system comprises a central processor module, a memory module and an input-output module which are connected with each other through a bus. The method is based on multi-channel image shooting, which has the advantages of more comprehensive image shooting and more information collecting for more useful data so as to contribute to significant improvement in the analysis of image. As the present invention uses the character identification technology based on Gabor filter groups to detect license plates, and as the method has the advantages of strong anti-interference performance, accurate identification, etc., the influence of the background on license plate images is eliminated. Therefore, even under less favorable conditions, the license plate images can be clearly analyzed, which improves the recognition rate of license plates.
