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, causing immense frustration for the user. Is it safe? I guess, cars that don’t move generally are. Is it functional? No, not at all.
I’m not advocating unsafe implementations here, I’m just pointing out that your suggestion doesn’t actually solve the issue, as it leaves a solution that’s not functional.
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.
All sensors throw a shitload of false positives (or negatives) when used in the real world, that’s why the filtering and unification between sensors is so important, but also really hard to solve, while still getting a consistent and reliable solution.
“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
