针对至今国内外媒体对“从太空看长城”问题仍不断出现的各种似是而非的说法误导读者，进一步阐述人眼从光觉、色觉，发展到形觉的机理，以及产生平面形觉、立体形觉受制于观察物体大小与距离的理论依据，同时展示了笔者进行的卫星遥感试验的主要成果。在此基础上，针对至今反映出来的5种主要看法一一进行剖析，进一步确认肉眼不可能从太空轨道看到长城，只有达到一定空间分辨率的卫星遥感才能获得长城影像的结论。
From the mechanism of optical sensing, color sensing and shape sensing of human eyes, this paper shows that the plane shape sensing and solid shape sensing depend on the size and the distance of the observed objects. With this point of view in mind and with the main research results of the Great Wall remote sensing image processing, various statements on this issue are analyzed and it is shown that human eyes can not see the Great Wall from space orbit, which can only be seen from the Great Wall image of high spatial resolution satellite sensing.
