Using the visual horizon to estimate aircraft attitude

This video demonstrates some of the research into visual guidance systems for UAVs being undertaken by the biorobotics lab at the Queensland Brain Institute. In this video, a wide-angle vision system is used to capture a near-spherical field of view of the environment. The input images are classified into sky and ground regions to estimate the attitude of the aircraft. The classifier is updated continuously and is therefore able to adapt to changing environmental conditions. This video shows the system functioning on images captured during flight tests and on images taken from flights performed by others. The top panel shows the raw image stream overlayed with the computed horizon (and possibly other reference horizons), while the bottom panels show the horizon estimation process.
