Can I ask a dumb non-engineer question? Backup cameras in areas with basically any road debris/weather get covered with dirt. I'm in the Seattle area now, and I often lick my thumb and wipe off the camera, because its a vision system I rely on so I don't kill people.
Could lidar/cameras/etc on the vehicle be obscured by road debris or worse, things being bumped/moved, smudged, or even foul play?
- nikanj 9y agoI think any dirt on a sensor would register as additional objects in the scenery, not missing objects. Humans are great at autocorrecting, but from a straight-up sensor data point of view, no light on these pixels=something is between sensor and light source.
- lisper 9y agoYes, that's possible. But in such a situation the data from the LIDAR looks very different than it does under normal conditions. You can easily tell when a backup camera is covered with dirt by looking at the image. Uber's self-driving software should have been able to detect a LIDAR failure in much the same way.
- hnaccy 9y agoYou would have Lidar wipers[1] and the software should hopefully be able to detect obscured or failing sensor and alert driver or stop. [1] https://i.imgur.com/2QTHjij.gifv https://i.imgur.com/2QTHjij.gifv
- skybrian 9y agoIt's easy to check for and would show up in recordings. I would be very surprised if they don't already check for this.
- colordrops 9y agoThere should be an alert of some sort and the car refusing to drive if the LIDAR is obstructed.
