Six boffins mostly hailing from Singapore-based universities have proven it's possible to interfere with autonomous vehicles by exploiting their reliance on camera-based computer vision and cause them to not recognize road signs.
How do non-camera based systems (lidar etc) get road sign information? I would expect with cameras...?
- bennyhill 2y agoWith cameras alone it seems pretty easy to trick them into dismissing road signs as nonexistent.. I think Lidar alone should be telling you there is a sign, so your camera is faulty or someone is putting up blank signs. Lidar as I was told to use it would be in conjunction with a database of way points like signs, so the trouble would be knowing if the sign was updated.
- recursive 2y agoMy car doesn't seem to have any trouble reading temporary construction speed limit signs and the like. And it has lidar. This seems to be a solved problem.
- bennyhill 2y agoAre you saying it exclusively has lidar? If not then I don't understand your comment.
- recursive 2y agoIt also has cameras. I might have assumed too much. I don't know how it determines the existence of a sign. It might be visual, lidar, or a combination. I think I drew a faulty and unstated inference. Feel free to disregard.
