This is somewhat tangential, but I want a model that can detect physical objects placed on top of a board from a picture/video, specifically warhammer 40k models.

I want a model that can detect the actual units/models that are placed on top of the terrain/board so I can track how the models move during the game, but trying gemini and chatgpt they were absolutely rubbish.

Amiibo and Skylanders detect the pieces with NFC. Wiring up the whole board/ terrain with NFC readers would probably be difficult, though.

		The other classic approach has been a single camera under the table, but that conflicts with terrain use. mmWave radar is probably good enough for to localization at this point, and cheap, but distinguishing pieces is hard.
