Design And Analysis, License Plate Recognition System Based On Optical Character Technology

Vehicle License Plate Recognition traveling as the only signs may be in the management of vehicle control and management of the vital role to play. In today's high-speed application of IT technology is the time for license plate recognition system technology research will enable the highway, city roads, parking, etc. on application management.This article on the license plate recognition system at the study, the comprehensive use of a dynamic video or still images to license numbers, license automatically identify the color of the pattern recognition. Through the image acquisition and processing, complete the license plate automatic recognition function, can automatically extract an image plate images, automatic segmentation of characters, and thus to identify characters. Its core, including license plate location algorithm, license plate character segmentation algorithms and optical character recognition algorithm. Finally on the characters deal with normalized; on the partition after the license plate characters, General considered the characteristics of license plate characters, based on BP neural network license plate character recognition method, the design of digital neural networks, and at the same time the use of VB development SQ SERVER 2003 instrument with the implementation of the image pre-processing, as well as the various stages of License Plate Recognition correlation algorithm, give the specific results of treatment.
