I’d recommend handing this task off to some company that has experience in these things. there are bound to be some that already have a solution ready to buy, or something they can customize quickly. this is not something you can sensibly foist off on some freelancer or one-man “company”.
is anything useful printed on the top of the container? if so, there goes the camera.
if not, I’d place it near the pivot point of the arm.
or further forward, but then you might need something more fisheye.
the cognitive/AI part will not be a weekend project. far from it.
and all the regular software engineering to collect and manage all the data is a whole project of its own.
you really need to call up companies.
