DoubleStar: Long-Range Attack Towards Depth Estimation based Obstacle Avoidance in Autonomous Systems [article]

Ce Zhou
2021 arXiv   pre-print
Depth estimation-based obstacle avoidance has been widely adopted by autonomous systems (drones and vehicles) for safety purpose.  ...  By exploiting the weaknesses of the stereo matching in depth estimation algorithms and the lens flare effect in optical imaging, we propose DoubleStar, a long-range attack that injects fake obstacle depth  ...  This work is supported in part by the National Science Foundation grants CNS-1950171, CNS-1949753.  ...
