"The pedestrian becoming visible" would be to the video cameras. If the vehicle has other sensors (LIDAR, RADAR, etc), how sooner/later would the pedestrian be visible to these sensors? Would it be possible to judge that by looking solely at the dashcam? Would the sensors ignore the pedestrian as a false positive in these circumstances?

That's what I wonder. Yes, it has LIDAR etc. But there was this comment yesterday by arbie:[0]

> Sensor Fusion typically merges LiDAR with stereoscopic camera feeds, the latter requiring ambient light.

So might LIDAR data get de-emphasized when there's too little light for the cameras?

If there’s not enough light for the cameras, LIDAR would get emphasized, not de-emphasized.

Thanks. So in this case, how come the woman wasn't identified based on the LIDAR data?

I don't understand that comment. "Sensor fusion" is the integration of data from two or more different sensors. It doesn't matter what those sensors are. They don't even have to be different types of sensors.

It may well be that the Uber cars only have LIDAR and optical, but that doesn't have anything to do with sensor fusion.

I didn't mean just visible as in visible light visible - I mean detected in any way by the systems.
