Cruise and Waymo have lidar. Lidar can give you much more certainty about detecting objects and distances. Teslas only use cameras and have to do complex image analysis to detect objects.
On the other hand lidar is more expensive. But it is getting cheaper and it does seem like it might be necessary for actual self driving.
- Someone 4y agoHaving LiDAR may make it easier to implement, but there are plenty of humans who can drive well without LiDAR, so having LiDAR isn’t necessary.
- hristov 4y agoThe human brain is far faster at image processing than any computer you may be able to put in a car. So shortcuts are necessary. Perhaps one shortcut is to get actual reliable object shape and position data from Lidar than trying to infer it from flat images.
- petilon 4y agoWe don't want robots to make human-level mistakes. Robotic drivers should work much better than humans, otherwise they should not exist.
- alephxyz 4y agoThe train appears on the car's HUD and the distance appears to be calculated properly before it tries to turn in front of it. I don't think object detection is what went wrong in this case (which is scarier imo).
