Method for compensating image dithering of airborne imaging equipment

The invention provides a method for compensating imaging dithering of airborne imaging equipment. The method adopts a rate gyroscope to measure the angular speed of the visual axis of a CCD camera inreal time, obtains the angular displacement of the visual axis by using an integrator for integration, measures the practical using focus of an optical zooming system by a displacement sensor, obtainsthe image displacement value of the CCD camera at the image surface due to the dithering by the calculation of a computer processing unit, and carries out reverse compensation to the image. The method has simple structure and brief algorithm, reduces calculation workload, inhibits the dithering of the image and improves the quality of the video image.
