Fooling LiDAR Perception via Adversarial Trajectory Perturbation

ICCV 2021poster

LiDAR point clouds collected from a moving vehicle are functions of its trajectories, because the sensor motion needs to be compensated to avoid distortions. When autonomous vehicles are sending LiDAR point clouds to deep networks for perception and planning, could the motion compensation consequent…
