Identified In The Research And Application Of Automatic License Plate Recognition System Based On The Overall Characteristics Of Numeric Characters

Based on the technology of recognizing images and characters ,the Vehicle License Plate recognition system is a kind of intelligent transportation management system developed recent years, One of the internal and extern a focused researches in the researching area recently which is on the application of pattern recognition. Nowadays, with the high-speed development of the economy, the amount of automobile is increasing rapidly, traffic and communication has been a bottleneck of the development the economy. For resolving this problem, more and more attention is being paid to the application of telecommunication and computer technologies in transportation Thus, the ITS(Intelligent Transportation System) is applied more and more widely The LPR (License Plate Recognition) is the important form of the ITS. The automatic recognition for the number of license plate is its foundation. It can do much something for vehicle, such as auto checking, validating, stakeout, giving an alarm and so on. Comparing with the traditional transportation management, it may enhance the efficiency and level of vehicle management, and may also economize manpower and material resources greatly.The investigation in LPR refers to the fields of digital image processing, computer vision, pattern recognition and artificial intelligence, and the key technique of it consists of plate location, character segmentation and character recognition.In this article, some new algorithms and methods concerned are introduced relatively in detail in such stage, as Pre-Processing of images, feature extraction, character classification and recognition on the foundation of the concise introduction to the work of the Vehicle License Plate's characters recognition. At the same time ,as far as the present state of a fairs...
