[Abstract]:This paper takes the urban monitoring bayonet system as the research object, uses the communication technology, the computer technology, the image recognition technology, and takes the embedded development thought as the foundation, introduces the overall design of the urban monitoring bayonet system. Vehicle recognition module design and license plate recognition module design. Based on the theoretical analysis and the investigation of urban traffic safety, this paper discusses the overall requirements, functional requirements and performance requirements of the urban monitoring and control bayonet system, and expounds the basic principle and overall design scheme of the system. The overall design of the system is completed. By using the techniques of high-definition camera, intelligent image processing, pattern recognition, digital transmission and storage, the intelligent bayonet system composed of the monitoring system at the road junction and the electronic police system is used to realize the recording and tracking of illegal vehicles. Based on image recognition technology, an automatic license plate recognition module is developed. The license plate location, character segmentation and character recognition technology are realized. The program code is written and the test system is made. The real-time and accuracy of the license plate recognition module are verified by experiments. Based on the overall design of smart card port system and image recognition technology, this paper realizes license plate recognition and location technology. And through the actual vehicle test to record and track illegal vehicles, verify the high efficiency and accuracy of license plate recognition technology, and put forward a new idea for the overall design of smart card port. It lays a solid theoretical foundation for the wide application of smart card port technology.
