It seems a legitimate question. I have never worked on this problem either but I would have thought that detecting a stationary object right in front of the car should be one of the basic and simpler functions of a self driving system.
Obviously this doesn't seem to be the case but maybe you can enlighten us why this is hard?
- bobsil1 8y agoFalse positives from road signs, overhead signs, radar-reflective trash. Commonly used radars have limited vertical discrimination.
- lagadu 8y agoWhy would the radar even be pointed at areas several meters above the car? Maybe radars can't be pointed at a narrow space, if that's the case why not use lidar instead?
- bobsil1 8y agoMost radars aren't coherent like laser, beams spread out. Also radar measures speed more accurately than location. Lidar only used by R&D + taxi services, price not reasonable for car buyers yet.
