Well, lidar is just a stand-in for the depth perception humans already do. It is absolutely valid for regulators to require that the systems on an autonomous car do depth perception, and provide a standard to prove that the system works well.
I suspect that right now, ML based approaches to depth perception would not pass the test to standards we would like, in practice requiring lidar. But, this would also provide an option to switch to an ML based gets good enough.
- acadien 6y agoThis is a common misperception. You cannot estimate the shape of simple things in low light. Even humans are susceptible to optical illusions and are effectively blind during certain times of day (try driving in the direction of the sun during sun rise/set). Lidar is not susceptible to any of these things. Similarly ML will never solve low light or direct light situations, that is a physical limitation of cameras.
- tshaddox 6y agoThere are popular cars in the US that use two cameras for their self-driving functionality. Kinda like humans.
- lttlrck 6y agoThose cameras are fixed whereas eyeballs have multiple degrees of movement via the eye socket and skull mounting apparatus allowing very sensitive parallax measurements. It's really not the same at all.
