Abstract
A method for adjusting a pointing angle of an actively stabilized camera is provided. The camera is housed by an active stabilization system configured to stabilize the camera in accordance with a commanded pointing angle. The active stabilization system comprises a steering member rotatable around one or more of a pan axis, tilt axis, and roll axis of the system. The method comprises: deriving a joint angle measurement of the steering member associated with a rotational movement of the steering member and adjusting the pointing angle of the camera, based on the derived joint angle measurement, in a direction of the rotational movement of the steering member, if the joint angle measurement exceeds the threshold window. If the joint angle measurement is within the threshold window, the pointing angle of the camera is actively stabilized in accordance with the commanded pointing angle.
