Electronic Toll Collection System Using ANPR

This paper proposes the Raspberry pi based toll collection system for automatic toll tax collection. It implements an automatic electronic toll collection system using Raspberry Pi and the image processing technology which uses a vehicle's number plate to identify the vehicle and collect the respective tax. The system is implemented using the ANPR algorithm for the extraction of number plate characters from the image such that we would take images of the vehicle which is sensed from distance using IR sensor and give the images as input to image processing where the number plate will be extracted, segmented and it is simulated using python?s OpenCV and other OCR libraries. The extracted number plate characteristics is again given as input to Raspberry pi and it verifies with the data present in the database and if it matches then the toll will be collected according to the vehicle?s parameters. And after the toll is collected, the gate would automatically open. If the vehicle number plate is unauthorized or not available in the database then it will send a message to pay money manually.
