topDown camera, Movement Detection and Coordinate

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

Ahhhhh! that’s it! easy peasy! it actually works well. thank you!
