This is also being done in retail, where manufacturers and/or distributors pay for preferred placement (end caps, eye level, etc), but how do you check that e.g. Safeway is really doing that across a couple of thousand stores?

You hire minimum wage people to walk around stores with cameras. This was actually done with notepads occasionally, but so much less expensive tondo with AI.

True, in-store planogram compliance and floor-plan compliance have got in focus again. It never lost the focus to be honest, just that now there is an expectation to do it while ensuring nothing fall through the cracks.

But there is a much more stringent privacy requirement here since customers walking in those stores haven't really signed up for this analysis. Hence, difficult to just setup the camera and take continuous data for analysis.
