Human pilots don't really use vision to see depth when flying - most things in flight are too difficult to judge distance/size, so one learns to fly without.

As for radar, most planes don't have their own radar. About all you're gonna get for anything close to depth is al altimeter.

to be fair, we're also usually not flying around inside a room

Humans don't get depth information past some distance that is probably pretty small compared to how far away objects are in flight. Past that point it's all contextual.
