Vehicle License Plate Recognition Design And Implementation

With the China's rapid economic development and the increasing volume of cars tenure, How to strengthen the traffic management and improve the efficiency in the using of the road, more to the government and the focus of attention of the relevant departments, in view of this problem, Intelligent Traffic Management System (ITS) as road traffic management trends. And vehicle license Automatic Recognition System is the core of the intelligent traffic management system. Based on the system can be added to certain derivative some other functions, which can be widely used in highway toll booths, parking, traffic intersection points, so that the management fees more closely, more scientific. Based on the current technical experience has been a great deal of research and reference of the current on the basis of research results, the basic realization of a digital image processing technology based on the license plate number of characters in the character recognition, image preprocessing, including vehicles, vehicle license positioning the vehicle license image processing, license plate characters division of the license plate character recognition several aspects. Comprehensive use of a digital image processing technology in the color image gray, gray image binarization, image-color, character segmentation, character normalized treatment, characters austerity rearrangement, as well as neural network characters recognition.
