In order to meet the requirement of rapidly deblurring aero-optical degraded image of high-speed reconnaissance aircraft, a rapid restoration method is proposed. By using a guide whose shape, size, and position information are unchanged in the reconnaissance images, the degraded function of the motion blurred image is effectively extracted, and then a inverse filter algorithm is employed to restore the blurred image. In our algorithm, all restoration works are finished only in five steps, so it greatly reduces computation time. A motion-blurred image with a resolution of 1600×1200 is restored only in 0.86s. The experimental results show that the proposed method has distinct advantages of fast computation and preferable effect.
