True, but LIDAR should make that detection more robust.
For example, if a stop sign is on the same plane as the object that surrounds it, that's a strong signal that it is not a real stop sign but rather a projected or displayed one.
That's much harder to detect with computer vision alone, especially if they're dealing with hackers who can test it with a real car and continually iterate on it to find different ways to trick it.
- nitrogen 6y agoFor example, if a stop sign is on the same plane as the object that surrounds it, that's a strong signal that it is not a real stop sign but rather a projected or displayed one. It's conceivable that in denser or older areas, signs are sometimes placed on structures because there isn't room for a pole.
- bonestamp2 6y agoAgreed. I didn't say it's definite, I said it's a strong signal. Even strong signals need to be weighed against other available data. Apple Maps shows stop signs and traffic lights on the map. A database like that would be another strong signal, but also not always accurate.
