卫星平台震颤影像的去模糊方法
Image deblurring method for satellite platform caused by jitter
摘要
Abstract
TDI CCD camera with its multi-level integral imaging features has become the mainstream sensor of current high-resolution optical remote sensor imaging system, but if there is platform tremor in its imaging process, it will pro-duce images blur, affecting image quality. The influence of platform tremor on imaging quality based on the imaging principle of TDI CCD camera was analyzed. According to the jitter image trajectory obtained by jitter detection, a method was proposed to eliminate image degradation caused by jitter. ZY-3 multi-spectral images were experimented. The expe-rimental results show that the quantitative evaluation index of the image after the jitter image is improved, and the validi-ty of the method is verified.关键词
