Abstract
People who are visually impaired encounter regular obstacles when trying to detect and move around their surroundings. The research presents "Third Eye" which represents a cost-effective wearable system for blind users that uses Raspberry Pi 4 as its operating platform. Through its camera the system obtains live visual inputs which leads to object detection processing with YOLOv3, Haar Cascade and SSD before issuing audio feedback through Google Speech API. This system based on OpenCV technology within Python works to convert surrounding visuals into descriptive audio output which improves user independence and awareness. The evaluation demonstrates that YOLOv3 performs object detection with accuracy rates spanning 80% to 99% which results in a mean Average Precision (mAP) of 31.05% while processing frames that operate at speeds from 10.12 to 16.29 FPS for real-time applications. The system stands as an affordable substitute to advanced assistive equipment because it enables visually impaired users to improve their lifestyle.
