| Abstract: | A compensation technology for the image motion of the full-frame CCD aerial camera is proposed. Exposal is continued when the shutter of the Full-Frame CCD is opened. The transfer speed of the charge can be controlled based on the different flying height and velocity. The pause pulse is intervened timely and the vertical transfer speed is changed accordingly. The theories of how to calculate the number and the cycle of the pause pulse are demonstrated, which are helpful in the fields of large resolution digital aerial camera in the future. A good result of compensation for the image motion of the full-frame CCD is shown by the experimental image. |
