I hope someone doesn't use this as inspiration for an exploit against LIDAR. On second thought, I hope people do start working on an exploit, so engineers can get on with hardening systems against it!
- totalZero 9y agoThe use cases I know of for lidar don't usually include a glancing reflection off a large flat surface.
- stcredzero 9y agoColliding with a large angled piece of sheet material in the middle of a roadway doesn't sound pleasant.
- LeifCarrotson 9y agoWhile I agree that the sensor systems should image just about anything you can imagine, wouldn't a large angled reflective sheet produce a shadow that could be distinguished from normal road surfaces and avoided?
- stcredzero 9y agoThat's a good 1st cut. But if we review the prior art -- namely stage magic's tricks with mirrors -- what's to stop someone from putting something in the region of the reflected image that would be expected by the driving AI? So, if what's expected are bushes in the background, why not aim the mirror at other bushes at the right distance?
- ChuckMcM 9y agoI built a number of robots that use infrared distance sensors for object detection and collision avoidance. Sadly the stereo cabinet I had made myself and painted flat black appeared invisible to them. Several robots ran into the cabinet at full speed :-(. The mitigation was to add another sensor (ultrasonic) which was better at seeing solid surfaces (but same problem as the bats for off angle approach).
