Comment on Tesla Whistleblower Says 'Autopilot' System Is Not Safe Enough To Be Used On Public Roads
ZapBeebz_@lemmy.world 9 months agoAfter a point, yes. However, that point comes when the sensor you are adding is more than the second type in the system. The correct answer is to work into your algorithm a weighting system so the car can decide which sensor it trusts to not kill the driver, i.e. if the LIDAR sees the broadside of a trailer and the camera doesn’t, the car should believe the LIDAR over the camera, as applying the brakes and speeding into the obstacle at 60mph is likely the safer option.

Yes the solution is fairly simple in theory, implementing this is significantly harder, which is why it is not a trivial issue to solve in robotics.
I’m not saying their decision was the right one, just that his argument with multiple sensors creating noise in the decision-making is a completely valid argument.

Doesn’t seem too complicated… if ANY of the sensors see something in the way that the system can’t resolve then it should stop the vehicle/force the driver to take over

Then you have a very unreliable system, stopping without actual reason all the time, cause immense frustration for the user. Is it safe? Yes. Is it functional? No, not at all.

If they’re using such unreliable sensors that they’re getting false positives all the time the system isn’t going to be functional in the first place.

“seeing an obstacle” is a high level abstraction. Sensor fusion is a lower level problem. It’s fundamentally kinda tricky to get coherent information out of multiple sensors looking partially at the same thing in different ways. Not impossible, but the basic model is less “just check each camera” and more sheafs
