遥感成像中CCD拖影问题的处理

由于应用需要与工作环境的限制,在设计遥感传感器时侧重于系统的可靠性与稳定性,简化的设计在CCD的曝光触发和机械快门上存在缺陷,造成了CCD的拖影问题,使遥感数据与遥感图像产生了一定程度的失真。针对自研发遥感成像系统中的CCD拖影问题,提出了逆向逐行修正的方法,利用该方法修正遥感数据得到的遥感图像对比度和图像质量显著提高,图像细节予以呈现。

Disposal of smearing in CCD remote sensing

As a result of application requirement and work environment restriction,the design of remote sensor lays great emphases on system security and stability,therefore the simplified design has deficiency in CCD exposure triggering and mechanical shutter.This brings about the problem of CCD smearing,which leads to the distortion of remote sensing data and images.To solve the smearing problem of our self-developing CCD remote sensor system,we put forward a reversely stepwise correcting method.The images retrieved from remote sensing data after correction have a notable improvement in image contrast and quality and the image details come forth.
