In my case, one of the external cameras points at where the bins normally reside. Each has a distinct colour. I wrote a simple algo that bins colours on the image coming from the camera, and, accounting for things like direct sunlight skewing the distribution, tells me which bins are currently on the street. That was pre-LLM age, these days I would have told claude to write that thing for me. Works as a charm, no batteries nor maintenance of any type. Runs on pyscript.
