Autonomous flying cameraman with embedded person detection and tracking while applying cinematographic rules

Boekbijdrage - Boekhoofdstuk Conferentiebijdrage

Unmanned Aerial Vehicles (UAVs) enable nu-merous applications such as search and rescue operations,structural inspection of buildings, crop growth analysis inagriculture, performing 3D reconstruction and so on. For suchapplications, currently the UAV is steered manually. However,in this paper we aim to record semi-professional video footage(e.g. concerts, sport events) using fully autonomous UAVs.Evidently, this is challenging since we need to detect and trackthe actor on-board a UAV in real-time, while automatically –and smoothly – controlling the UAV based on these detections.For this, all four DOF (Degrees of freedom) are controlledin separate simultaneous control loops by our vision-basedalgorithms. Furthermore cinematographic rules need to betaken into account (e.g. the rule of thirds) which positionthe actor at the visually optimal location in the frame. Weextensively validated our algorithms: each control loop andthe overall final system is thoroughly evaluated with respectto both accuracy and control speed. We show that our systemis able to efficiently control the UAV such that professionalrecordings are obtained.
