Kidnapping Deep Learning-based Multirotors using Optimized Flying Adversarial Patches

1 code implementation1 Aug 2023 Pia Hanfeld, Khaled Wahba, Marina M. -C. Höhne, Michael Bussmann, Wolfgang Hönig

We introduce flying adversarial patches, where multiple images are mounted on at least one other flying robot and therefore can be placed anywhere in the field of view of a victim multirotor.
