文章在简要介绍遥感器在轨MTF评测值在遥感图像处理中的意义基础上,分析了中分辨率遥感卫星成像过程MTF在轨测试的各种方法的适用性、算法和具体指标要求,提出了适合于中分辨率遥感卫星成像过程MTF的在轨评价方法,并剖析了遥感卫星成像过程中影响MTF的多种因素;最终以CBERS-02星CCD图像为对象进行了试验,并有效运用于图像恢复。
Based on the introduction of the significance of in-orbit MTF evaluation of remote sensors in remote sensing image processing, this paper analyzes the applicability, algorithm and specific index requirements of MTF in-orbit testing for medium-resolution remote sensing satellite imaging process Which is suitable for in-orbit evaluation of MTF in medium-resolution remote sensing satellite imagery process, and analyzes many factors that affect MTF in remote sensing satellite imaging process. Finally, the CBERS-02 CCD imagery is tested and effectively applied to image restore.
