Through video images of detection and recognition of the road, road traffic flow, monitoring, etc, the traffic flow information extraction, through video images of detection and recognition, still can real-time detection and identification of violate the traffic violations phenomenon plate number for public security traffic management department, provide strong evidence of law enforcement. Therefore, the study traffic image processing methods of testing and the development of intelligent transportation system plays an important role. This thesis mainly on traffic image processing technology for detection and do research, and put forward some effective and practical, quick recognition algorithm. Main application VB language program, to the license plate identification, orientation, image analysis, processing. And some of the mistakes in recognition, positioning problem. Keywords: plate；Positioning； Identify； Pretreatment；Mathematical mor
