In this example, I wanted to implement concepts of Computer Vision.

This work is inspired by Andrew Ng’s Landing AI team, who created a Social Distancing Tool. I’ll be using the YOLO v3 Object Detection Algorithm and OpenCV library.

This tool has the following features:

1. Transform the perspective of view to a bird’s-eye (top-down) view.
2. Detect persons in the frame with yolov3 and project the points in bird’s eye view.
3. Compute Euclidean distance between every point.
4. Calculate the percentage of persons who do not respect social distancing.
