enter image description here

enter image description here

i have question school project. given task of tracking volleyball given beach volleyball match video in mov format. task track ball , output whole volleyball court in birds eye view, , draw ball movement.

currently, im still doing ball tracking. however, not know how exactly. have thought of doing in way:

  1. get 4 corners of volleyball court using harris corner detectors
  2. use 4 corners find homography between different frames
  3. then remove background , player
  4. finally can track ball???

is thought process correct?

and have tried detect 4 corners using harriscorner detector. not 4 corners. 1 has suggestions? thank you
