CoHelix: Event-Based Multi-Propeller Rotation-Rate Tracking with Shared Projective Geometry
Radim Spetlik, Tobiáš Vinklárek, Jan Klivan +3
Estimating propeller rates from a moving event camera requires separating blade rotation from the changing image geometry. Background activity mixes with blade events, while repeat…
Towards Agile Vision-Based Multi-UAV Flight: Revisiting State Estimation
Michal Pliska, Matouš Vrba, Ondřej Víta +3
Agile multi-UAV flight requires accurate and low-latency onboard estimation of the kinematic states of neighboring UAVs for collision avoidance, motion coordination, etc. Most visi…
Spacecraft Fiducial Marker for Autonomous Rendezvous, Proximity Operations, and Docking
