On Stability Augmentation for Camera Optical Axis Based on Attitude of Air Ship
This paper introduces a technology of stability argumentation for camera optical axis based on attitude of air ship. The attitude relative to the inertial coordinate system could be obtained by compass on air ship, then calculates the deflection angle between the camera optical axis and the origin target field, at last, offsets the change of camera optical axis cased by the movement of air ship by adjusting the rotating platform on air ship in both yaw and pitch directions. The test on air ship shows that the method mentioned in this paper is simple and practical, and the method could effectively resolve the problem which the attitude change of air ship could influence the camera optical axis on ship by adjusting the platform on air ship. The method could make the camera optical axis exactly find back the original target field and could keep the camera optical axis stabilizing.
