Abstract- Automatic Number Plate Recognition system i.e.ANPR system is an image processing technology. In this technology we use numberplate of vehicle to recognize the vehicle. Automatic Number Plate Recognitionsystem is used in various areas nowadays such as automatic toll collectionbooth, Border crossing locations, various parking system, Traffic controlsystem, tracking of stolen cars,maintaining traffic and law enforcementetc. several techniques have been proposed for plate recognition, each onehaving its own advantages and disadvantages. The task of recognizing numberplate for Indian conditions is considered, where number plate standards are notfollowed very stringently.
This ANPR system worksin four main steps to get the required information. These four steps are imageacquisition, plate localization, character segmentation and characterrecognition. The number plates which are not in the proper roman scripts mustbe changed into roman format for correct recognition of the number plate.Currently there is no facility in the ANPR system which can detect otherlanguage number plates like devanagari scripts used by some people. So usingpre-defined data for the training set which will convert non roman scripts intothe assigned format. Through this project we will be able to identify thenumber plates accurately even when they are not in the assigned format or font.
