An Automatic Number Plate Recognition System for Sri Lankan Vehicle Number Plates

This study aimed at designing an automatic number plate recognition system (ANPR) using OpenCV, Python, and Tesseract to extract the vehicle registration number in Sri Lankan vehicle number plates for the possible after use in vehicle registration compliance checking by the Sri Lanka Police (SLP). The key steps followed in the ANPR system were the image capture, image preprocessing by resizing, gray scaling, and blurring, number plate localization by edge detection and contouring, character segmentation and finally character recognition. At the end, the accuracy of the system was tested using 10 sample images of Sri Lankan vehicles, which showed an accuracy percentage of 90% in number plate detection
