Yes, human vision is so bad it has to rely on a swivel joint and a set of mirrors just to approximate 360 coverage. Modern cars can have 360 vision at all times, as a default. With multiple overlapping camera FoVs. Which is exactly what humans use to get near field 3D vision. And far field 3D vision? The depth-discrimination ability of binocular vision falls off with distance squared. At far ranges, humans no longer see enough difference between the two images to get a reliable depth estimate. Notably, cars can space their cameras apart much further, so their far range binocular perception can fare better. How do humans get that "3D" at far distances then? The answer is, like it usually is when it comes to perception, postprocessing. Human brain estimates depth based on the features it sees. Not unlike an AI that was trained to predict depth maps from a single 2D image. If you think that perceiving "inertia and movement" is vital, then you'd be surprised to learn that an IMU that beats a human on that can be found in an average smartphone. It's not even worth mentioning - even non-self-driving cars have that for GPS dead reckoning. |
