I tried two-dimensional picking.
We tested position detection for picking by robot.
It is two-dimensional, not three-dimensional.
First, a positioning model is created with one piece, and up to 10 pieces are detected.
Detection in 1 piece

Detection with 6 pieces

Detection with 20 pieces

Detection in screw boxes

Three-dimensional position detection" may be all the rage, but if we are only talking about "to grab or not to grab" and "where to grab," I feel that two dimensions will suffice.
