That's not how the geo-fence works. If the car solely used geo-fence it wouldn't be able to handle simple things like other cars on the road. Obviously, that's not the case.
Geo-fence lets the car know that the road has been mapped so that it can correlate its sensory data against fixed data.
Rain reduces the operational distance of a LIDAR system but does not render the system useless. On the other hand, tests have shown that more than moderate amounts of rain (i.e,. more than a sprinkle) will render a camera-based system useless at both recognizing objects and at determining distances. https://ouster.com/blog/lidar-vs-camera-comparison-in-the-rain/ https://ouster.com/blog/lidar-vs-camera-comparison-in-the-ra... (Most car manufacturers have already stated they will not let their advanced driving functions work in snow for safety reasons.)
- labcomputer 6y ago> Geo-fence lets the car know that the road has been mapped so that it can correlate its sensory data against fixed data. Yes, I get that, and my point is that updating the geo-fence fast enough to account for changes in the ground truth which invalidate your map is an unsolved problem.
- gamblor956 6y agoNo, you're not getting it. Geo-fence is the backstop safety mechanism for SuperCruise, not the primary mechanism. They don't need to update geo-fence to account for changes to "ground truth." The whole point of the geo-fence is to confirm sensor data and assist in identifying anamolous situations like accidents and construction. If sensor data doesn't match "truth" then the self-driving system can engage safety mechanisms, engage additional processing, or disable self-driving as appropriate.
