Electronic Toll Collection Using Automatic Number Plate Detection System

Abstract

Electronic toll collection using automatic number plate recognition (ANPR) system is designed for collection of toll fare on toll booths without manual assistance using digital image processing. We are aware of the drastic increase in number of vehicles recently, hence it is necessary to digitalize the information record of these vehicles. The electronic toll detection system other than its primary goal, makes it possible. We propose a system which performs various digital image processing algorithms on the image of vehicle and segments the license plate into individual characters. The proposed system takes a picture of license plate and extracts the number plate. The extracted number plate is then compared with already stored database of vehicle and its type. Accordingly, the fair is displayed. The system does so using the combination of suitable algorithms in accordance with the application, hence proves to be highly efficient and fast. We perform character extraction, character segmentation and recognition work, using English characters and numbers in MATLAB software.
