Using the visual horizon to control 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-hemispherical field of view of the environment. From these images, the view rays that correspond to the visual horizon are found by segmenting the colour space into two classes. The attitude of the aircraft is then measured by fitting a great circle to the reprojected horizon view rays. This information is then used in a control loop to stabilise the attitude of the aircraft automatically. This video demonstrates the ability of this system to control the attitude of the aircraft accurately during sustained accelerations. The left panel shows the image stream from the visual system onboard the aircraft overlayed with the view rays identified as corresponding to the visual horizon (green), and the reprojected visual horizon (red), while the right panel shows a visualisation of the estimated attitude of the aircraft.
