Using 3D Shadows to Detect Object Hiding Attacks on Autonomous Vehicle Perception. (arXiv:2204.13973v1 [cs.CV])

Autonomous Vehicles (AVs) are mostly reliant on LiDAR sensors which enable
spatial perception of their surroundings and help make driving decisions.
Recent works demonstrated attacks that aim to hide objects from AV perception,
which can result in severe consequences. 3D shadows, are regions void of
measurements in 3D point clouds which arise from occlusions of objects in a
scene. 3D shadows were proposed as a physical invariant valuable for detecting
spoofed or fake objects. In this work, we leverage 3D …
