YOLOv5 Inference

Real-time object detection running on the Jetson Nano. The system identifies vehicles, pedestrians, and obstacles with high accuracy, translating visual data into audio cues.

Development Phase

Snapshots from the rigorous testing phase, calibrating the vision model to handle diverse lighting conditions and complex street environments.

THE_OUTCOME

NATIONAL RECOGNITION
SMART INDIA HACKATHON 2021

What started as a freshman year project evolved into a nationally recognized innovation. We won First Prize at the Smart India Hackathon, receiving accolades from the Ministry of Health.

GOVT_FUNDING_APPROVED

Selected by the Ministry of Health for production funding to scale the device for mass manufacturing.

The device successfully demonstrated that complex edge computing (Jetson Nano) could be miniaturized into a life-changing assistive tool, bridging the gap between "sight" and "sensing".
