topDown camera, Movement Detection and Coordinate

vvvv gamma question
1

Hello there.
I have a small project as a good exercise happening to me, and I need the starting point of it

here are the conditions :

  • 1 camera, top down in the space (attached to the ceiling, pointing toward the floor)
  • I need to detect people walking in the room, and get their coordinate live

what is the best course of action?
I tried mediapipe. I am not sure that i need things to be detected as a human or a dog. And I don’t know how to extract the coordinate (only vector 2 should suffice).
what shall I do?
I was thinking about the opticalflow2d from Tim (here), but I don’t know how to get each person as an unique entity and extract the coordinate…

thank you!

Maybe blob tracking in VL.openCV? you’ll need to install the nuget
