Perspective-Shift Attacks Against Optical Perception Sensors: A Novel Attack...
summary
Paper demonstrates that placing a transparent Direction Turning Film over LiDAR and camera optics produces a controlled 20° shift in field of view, causing measurable displacement in LiDAR odometry (KISS‑ICP) and a shifted vanishing point for cameras while leaving object detection confidences largely unchanged. Proof includes digital simulation, lab tests on Ouster OS1 and Falcon Shen Tu sensors, and real‑vehicle deployment with coherent multimodal shifts. Attack needs one‑time physical access and is stealthy; proposed defenses use reflectivity smoothing thresholds and an engine‑hood semantic check.
