INTRODUCTION
The Automatic Number Plate Recognition is a system designed to help in recognition of number plates of vehicles. This system is designed for the purpose of the security and it is a security system. This system is based on the image processing system. This system helps in the functions like detection of the number plates of the vehicles, processing them and using processed data for further processing like storing, allowing vehicles to pass or to reject vehicle.
In entrance gate, number plates are used to identify the vehicles. When a vehicle enters an input gate, number plate is automatically recognized and stored in database and not-listed number is not given
permission into the parking lot.
LITERATURE SURVEY
Automatic number plate recognition (ANPR) is a mass surveillance method that uses optical character recognition on images to read the license plates on vehicles. They can use existing closed-circuit television or road-rule enforcement cameras, or ones specifically designed for the task. They are used by various police forces and as a method of electronic toll collection on pay-per-use roads and cataloging the movements of traffic or individuals.
ANPR can be used to store the images captured by the cameras as well as the text from the license plate, with some configurable to store a photograph of the driver. Systems commonly use infrared lighting to allow the camera to take the picture at any time of the day. ANPR technology tends to be region-specific, owing to plate variation from place to place.
Concerns about these systems have centered on privacy fears of government tracking citizens' movements, misidentification, high error rates, and increased government spending.
Development history
The ANPR was invented in 1976 at the Police Scientific Development Branch in the UK. Prototype systems were working by 1979, and contracts were let to produce industrial systems, first at EMI Electronics, and then at Computer Recognition Systems (CRS) in Wokingham, UK. Early trial systems were deployed on the A1 road and DartfordTunnel.
Description:
• The system is developed as a security system.
• The webcam is fitted on the gate or on the wall opposite to the gate and when the vehicle comes in front of the gate ;the camera is automatically triggered when the sensor senses the arrival of vehicle it detects and captures the image of the vehicle with the number plate.
• The computer loaded with MATLAB software processes the image and saves the number plate. The captured image of number plate is then compared with the existing data base, if a match occurs, it sends command to parallel port of the computer and with the circuitry along with parallel port, the door is opened. When vehicles enters the gate, it closes the door
