3D Vision, Vision for Robotics, Artificial Intelligence (AI), Geometric Deep Learning, Camera Drones

Our research focus is the the area of 3D computer vision including vision for robotics. A specific focus is on the topic of computer vision for camera drones, e.g. for aerial image processing or camera based navigation. We operate a variety of camera drones of different sizes and also operate an indoor flying arena.
