It's not going to be reliable with just cameras.
You can use where the headlights disappear and reappear to draw an arc of occluded space. You should be able to measure how quickly that arc changes to estimate the distance
If you're 1000 feet from an object and move a foot closer, it barely blocks anything else from view. If you're 5 feet away, moving a foot closer blocks a lot more of your view.
The problem is that relies on nearly constant backlighting on the object.
The real solution here is LIDAR, which makes this trivial. Tesla won't use it though, so they have stupid problems like trying to hack a way to determine how far away dark objects are.
- dkonofalski 5y agoExactly. I was just going off of Musk's statements that they don't want to use things like LIDAR since people don't have LIDAR but can make these types of assessments. Even if you could make an arc of occlusion (sounds like a D&D spell), there's way too much variability in headlight sizes/designs to accurately determine distance in the dark in the situation this video presents. Again, I am admitting a ton of ignorance when making that statement but that seems nearly impossible to me with just cameras.
