摘要
提出一种全帧型CCD航空相机像移补偿的实现方法.应用全帧型CCD在机械快门不关闭的情况下连续曝光的特点,并根据不同的速高比控制暂停脉冲的个数和宽度,控制了CCD垂直转移的速度,使CCD在曝光的同时进行转移和读出,实现了全帧型CCD航空数码相机航向方向的像移补偿.实验数据表明:该方法能够实现全帧型CCD像移补偿的功能.
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.
