Ball impact tracking

Hi OFXers,
I want to build and installation with this kind of interaction : or
What is the best way to track the ball impact ?

  • Camera (ir maybe) ?
  • Lidar ?
  • anything else ?

My guess is ball tracking with multiple cameras… maybe special balls reflecting IR?

Laser would be difficult to use, as there are many obstructions (kids touching the wall, shelves etc)
