Let me make sure I get this:
When a Tesla (or other non-LIDAR) vehicle is driving, it is not continuously building a 3D model of its environment. Instead, it is matching patterns on the road, and "understanding" based off what it sees in an otherwise flat image.
Whereas LIDAR vehicles use the LIDAR technology to develop a map of the world around them, for additional understanding?
- unfamiliar 10y agoNo. They're both building a map and trying to place themselves in it. Using LIDAR makes this much easier to do.
- Animats 10y agoIt's not clear whether Tesla has a local map. They've never shown pictures of one, unlike Google. The Mobileye unit definitely does not; you can buy a Mobileye aftermarket unit and watch it put rectangles around things that look like cars and people. Tesla's radar probably just returns targets and range, like most first-generation automotive radars. Tesla's system may be entirely reactive. Google builds maps; they do path planning, so they have to.
- argonaut 10y agoIt's unclear if Tesla is building a 3D model or not. For the cameras, at least looking at Mobileeye's demos, it appears not. But Tesla also is using radar - it's unclear whether they're using the radar for just collision detection, or for building a full 3D map. LIDAR gives you a 3D map of the surroundings, yes.
