Comment on Waymo says its self-driving taxis will take customers on freeways for the first time

• KingRandomGuy@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

  I do research in 3D computer vision and in general, depth from cameras (even multi view) tends to be much noisier than LiDAR. LiDAR has the advantage of giving explicit depth, whereas with multiview cameras you need to compute it, which has a fair amount of failure modes. I think that’s what the above user is getting at when they said Waymo actually has depth sensing.

  This isn’t to say that Tesla’s approach can’t work at all, but just that Waymo’s is more grounded. There are reasons to avoid LiDAR (cost primarily, a good LiDAR sensor is very expensive), but if you can fit LiDAR into your stack it’ll likely help a bit with reliability.

    that is exactly what i meant by it yes, predictive depth using cameras is way less reliable as it is vs direct sensors that are expensive but if they cant make something cheaply that wont kill you it shouldn’t be sold period

  I’m glad someone else already said it but camera depth sensing is way less functioning and safe than these other sensors and is way more prone to environmental factors fucking with it. You should do some research instead of listing off something elon says without any understanding…

    Nothing I said is wrong. Using just 2 cameras you can do depth sensing.

      you cannot use 2 cameras to do safe and effective depth sensing, we have tests that prove how ineffective it is compared to other methods and it has insane rates of causing crashes to the point tesla is being sued over it. if you didn’t feel the need to shill for tesla you wouldn’t be saying this stupid shit

      all researchers completely agree on this reality that teslas depth sensing is not good and way more error prone so i don’t see why youre trying to defend a car that has literally killed people because of its failures

        Teslas don’t kill people lol.
