Hey! I ran the code on Google Colab and the code ran without any error. I think something went wrong while processing the frame.

can you share limitations and importance of the project

Limitations:
This project does not take into account the camera perspective.
It does not leverage a proper camera calibration (Distances are not measure accurate).

Importance:
Social distancing is deliberately increasing the physical space between people to avoid spreading illness. Staying at least six feet away from other people lessens your chances of contracting COVID-19. We can use OpenCV and YOLO to monitor/analyze whether people are maintaining social distancing or not. It could be used for just keeping a track whether people are maintaining social distancing.

hi may i know the 60 in safe distance is in what unit? and how you determine it?

Hi... As I have said in the limitations, this project does not take into consideration actual perspective. So, the 60 is just a rough estimate for safe estimate for this camera angle.

I've attached a file directory structure image above. So create a constants.py file accordingly and then add this:

YOLOV3_LABELS_PATH = './yolov3/coco.names'
YOLOV3_CFG_PATH = './yolov3/yolov3.cfg'
YOLOV3_WEIGHTS_PATH = './yolov3/yolov3.weights'
VIDEO_PATH = './videos/video.mp4'
OUTPUT_PATH = './output/output.avi'
SAFE_DISTANCE = 60
