Abstract
A active stabilization system and a method for correcting a pointing direction of a camera to compensate for translational movements of the camera are described. The system actively stabilizes a pointing direction of the camera in accordance with a commanded pointing angle. A distance from the camera to a filming target is determined and one or more translational measurements associated with a translational movement of the camera are derived. A correction update is calculated as a function of at least the distance and the one or more translational measurements. The commanded pointing angle of the camera is adjusted based on the correction update to retain the filming target within a field of view of the camera.
