A real-time despinning method for onboard video image was proposed.By loading the rotation angle signal produced by onboard gyroscope on the video image for wirelessly transmission,and the video signal was received by ground station and sampled,then the rotation angle was identified,and the stable image sequence can be obtained by rotating the image reversely frame by frame.The experimental result shows that the image despinning system can cancel the rotation of 720pixel×576 pixel×24bit image sequence in real-time with an accuracy of 0.5°and the per-frame processing time is about 40ms.
