Título: Vision-based Perception and Control Methods for Autonomous Aerial Robots
Ponente: Eric Cristofalo
Lugar: Seminario del Departamento
Día: Viernes 8 de febrero a las 10:30
Abstract:
Oftentimes in robotics, we treat the problems of perception and control independently. Active perception is a method that couples the two components by computing a control input that actively improves the quality of the perception. In this talk, I will present an active vision-based feedback controller for a quadrotor with a monocular camera that is attempting to reconstruct the unknown scene structure. The controller maneuvers the quadrotor in a fashion that minimizes the future uncertainty of its 3D reconstruction. We apply this method in simulation and on real quadrotors with downward-facing cameras. I will also present recent experimental results for autonomous drone racing with vision-equipped quadrotors that uses an iterative best response game-theoretic planner. The competing quadrotors estimate the position of their opponents by coupling on-board images and the predicted opponent trajectories generated by the game planner.
