Human beings radiate IR do they not? Silly question, of course they do. Perhaps not above an Arizona level of thermal background?

- gok 9y agoThermal imaging and near-infrared imaging are not the same. Waymo/Uber/etc are not using thermography for their autonomous vehicles.
- Balgair 9y agoWe see a nIR video of the driver. Those weird eyes everyone seems to have are the tell-tale sign of nIR as it interacts with the retina. So, we know that nIR sensors are being used in the interior, at least. That said, Arizona in the summer is going to play havoc with lIR and thermography in erms of false positives and negatives. The sensor suite probably should be using lIR at night for this reason and the switching it off in the day. But given Uber's history, the lack of lIR reeks of cost-cutting.
- rwbcxrz 9y agoI'm not an expert in IR or computer vision by any means, so take this with a grain of salt. Air has such a low thermal mass that it doesn't measurably affect most IR sensors. Hot pavement could be a potential issue, but that shouldn't have a major effect on forward-facing sensors. Besides, it's only March. Even Arizona isn't that hot yet.
