Core concept and project goal
The project 'AeRial outdoor motion CAPture' (AirCap) introduces the concept of multiple flying robots with on-board cameras to perform real-time full body pose and shape estimation of multiple people in outdoor scenarios. It has been partially funded by the Max Planck Grassroots Project Micro Aerial Vehicles-based Outdoor motion CAPture (MAVOCAP).
Human and animal full-body motion capture (MoCap) in outdoor scenarios is a challenging and largely unsolved problem. MoCap systems like Vicon, Optitrack and the 4D Dynamic Body Scanner at MPI-IS Tuebingen, achieve high degree of accuracy in indoor settings. Besides being bulky, they make use of reflected infrared light and heavily rely on precisely calibrated wall or ceiling-mounted fixed cameras. Consequently, such systems cannot be used to perform MoCap in outdoor scenarios where changing ambient light conditions persist and permanent fixtures in the environment cannot be made. Our outdoor MoCap solution involves flying robots with only on-board equipment, e.g., cameras, Intel i7 CPUs, NVidia Jetson TX1 GPU modules.
