A comprehensive review on helmet detection and number plate recognition approaches

Abstract

Motorbikes serve as the primary mode of transportation in most countries as they are cost effective and appropriate for a nuclear family. But it has been observed that more than 70% of the users do not prefer to wear safety helmets for various reasons jeopardizing their lives and falling prey to accidents. The most prevalent method for ensuring this right now is traffic police manually monitoring the motorcyclists. But due to excess traffic and limited traffic personnels, many violators go unrecognized and continue to practice the same. Thus, it is important to eliminate the human intervention and automate the monitoring system using deep learning and computer vision-based techniques. Our proposed system implements this by extracting number plate of helmet violators and generates an e-challan on the registered mobile number. We propose using a custom trained YOLO-v8 model for violation detection and YOLO-v8 + EasyOCR for number plate detection and extraction. Canny Edge Detection is a preprocessing step that can be used to enhance the edges of objects in an image, making them more distinguishable. This system holds great potential for enhancing safety-related policies and ensuring strict enforcement of traffic regulations. Additionally, it contributes to the advancement of traffic management through the implementation of an AI-based automated traffic violation and ticketing system.
