Doesn't this inevitably mean that the hardware isn't capable too with extra steps? Like in 20 years with tens of millions more lines of code, we're going to need more hardware resources to run it (in particular at near real-time) than the hardware would provide today.
I agree with you, to be clear. I am just pointing out that 20 years worth of software is going to be a monster to run at the timings that will be required. So we could hit a hardware limitation between then and now on top of the hard software problems that must be solved.
> Humans only have two eyes that can only look in one direction at a time, and we achieve L5.
Humans use parallax to perceive depth via the overlap of both eyes, which as far as I know isn't used by automated vehicles for reasons unknown (patents?). Automated vehicles using visible light cameras are mapping the world in 2D, humans perceive the world in limited 3D.
- TaylorAlexander 5y agoStereo vision is oversold in humans. You can easily drive with one eye. We use a lot of information to estimate depth including relative size of things, as well as “structure from motion” which is the relative movement of things over time. Tesla does estimate depth using structure from motion (and probably other cues). They call it virtual LIDAR in presentations. https://youtu.be/NSDTZQdo6H8 https://youtu.be/NSDTZQdo6H8
- gpt5 5y agoAbsolutely correct. This is why VR works really well for a person with only a single eye vision.
- codeulike 5y agoWhat? Of course they use parallax
- Someone1234 5y agoWho does? Parallax requires the cameras to be very carefully angled (toed-in), so they overlap in a very specific way, it isn't simply two cameras recording the same image straight. Most automated vehicles companies using visible light cameras have them pointed straight forward, that isn't therefore using parallax like a human does.
- Dylan16807 5y agoThat doesn't make any sense to me optically.
- dsr_ 5y agoParallax only requires you to know the separation and angles (and fields of view) of the cameras. Two parallel cameras at 1 meter separation and 90 degree fields of view are fine. You could change the separation and angles every frame, if you wanted, as long as you always did your calculations from the correct position data.
- sacrosancty 5y agoYou can do parallax depth-sensing without physically rotating the cameras like human eyes. OAK-D cameras do that with parallel pointed cameras.
