I'm a second year PhD Student at the department of Perceiving Systems.
I'm working on outdoor 4d scans using multiple aerial vehicles as self positioning autonomous and mobile camera/sensor platforms which we design and operate here at the institute. My current work involves integrating detections from real time deep neural networks into cooperative multi vehicle sensor fusion.
The goal of the project 'AeRial outdoor motion CAPture' (AirCap) is to perform on-board, online and real-time full body pose and offline shape estimation of humans and animals in outdoor scenarios, using a team of mic...

Multi-camera tracking of humans and animals in outdoor environments is a relevant and challenging problem. Our approach to it involves a team of cooperating micro aerial vehicles (MAVs) with on-board cameras only. DNNs often fail at objects with small scale or far away from the camera, which are typical characteristics of a scenario with aerial robots. Thus, the core problem addressed in this paper is how to achieve on-board, online, continuous and accurate vision-based detections using DNNs for visual person tracking through MAVs. Our solution leverages cooperation among multiple MAVs and active selection of most informative regions of image. We demonstrate the efficiency of our approach through simulations with up to 16 robots and real robot experiments involving two aerial robots tracking a person, while maintaining an active perception-driven formation. ROS-based source code is provided for the benefit of the community.
Our goal is to understand the principles of Perception, Action and Learning in autonomous systems that successfully interact with complex environments and to use this understanding to design future systems
