LIDAR is not the only way to record depth information. Saying that LIDAR is some kind of savior device is heavily into "solve all your fusion problems with this one weird trick" territory.
- SQueeeeeL 7y agoOkay, but from the statement, whatever alternative they're using isn't working
- totalZero 7y agoDon't be ridiculous. It's more like "see better with different glasses."
- ebg13 7y agoDo you have a paper comparing states of the art flash LIDAR to real time high density stereo that makes you think it's better? Because my experience with the field has been that lasers aren't better for this except for very specific non-real-world scenarios.
- ip26 7y agoWhy is a paper required? Many of Tesla's early self-driving accidents involved low contrast scenes where the system was unable to distinguish, e.g., a white object from a wall, or a blue object from the sky. This is always a weakness with optical, even for our own eyeballs.
- ip26 7y agoLIDAR is not the only way to record depth information When you mix two or more different ways of measuring depth you can increase the reliability of your system dramatically. See "sensor fusion". Optical-only has weaknesses. LIDAR-only has weaknesses. Optical plus LIDAR would be far more robust than either alone.
