Project's Overview
Automatic License Plate Recognition System is a Python Flask based final year project developed for detecting and recognizing vehicle license plates from uploaded images. This major project provides a modern browser-based interface where users can upload a vehicle image, preview the image, choose optional region hints, submit it for recognition, and view detected plate numbers with confidence scores, region data, vehicle details, candidates, and bounding-box overlays. The backend validates file type, file size, empty uploads, and sends the image to the Plate Recognizer Snapshot API. The frontend uses HTML, CSS, JavaScript, and Canvas to display professional results with copy-to-clipboard functionality. This ALPR system source code is suitable for students who need a final year project, major project, minor project, source code, and project report based on Flask, image processing workflow, API integration, and vehicle number plate recognition.
