Is it possible to see microwave ovens on the ground with a Rydberg antenna array for in-cockpit drone Remote ID signal location?

Recently I heard about an approach where they train a model to behave as a Lidar, using only camera inputs. Sounds like a cool, modular approach, but not sure about safety.

You can train those models all you want, the sensors still have some physical limitations. A regular camera operating in the visible spectrum won't be able to penetrate dense fog, where lidar or radar may still work.

amelius

True, but it's the same for a human driver.

KeplerBoy

Sure, but we should aim for superhuman driving capabilities, especially in conditions humans struggle.

Geee

Tesla FSD used to do this with occupancy networks [0]. It's basically a "software lidar". Afaik they don't use it any more in their newest FSD stack, expect for visualizations maybe.
