As of 2025 the pigeons are back and version 2 with aiming and a microphone array for target acquisition is still work-in-progress. I’m heading to bed now, but I’ll happily answer any questions tomorrow.
My setup also had its occasional false positives but that’s not a problem if all you do is spray a bit of water around. I also looked into yolo, but I couldn’t find any good datasets of pigeons. Nowadays that’s no problem anymore as you can just use models like meta’s segment anything that do zero-shot bounding boxes… if you have the GPU to run it.
But even with an llm backbone you’d still need some setup to detect when to query the llm. And then you already have a low-false-negative pigeon detector that may be sufficient for your use case.
