The Chang' e-2 lunar satellite was launched on October 1st, 2010. It has operated in-orbit about two years and has performed some extended science test besides finishing all the predicted engineering and scientific goals. The CCD stereo camera of Chang'e-2 satellite has collected 35 orbits' local images of the sinus Iridum area with about 1.3m spatial resolution,and has col- lected the global images with 7m spatial resolution which have the highest resolution and the most clarity in the world. The image collection is introduced, and the images collected in 15km/100km elliptical orbit and 100kin circle orbit are analyzed. The emphasis is the influence of sun height angle (sun elevation angle) on image vision effect and information capacity. The analysis results can be used as a reference for the planet explorations in China.%嫦娥二号月球卫星从2010年10月1日发射至今，已在轨运行近2年，除全部完成预定的工程与科学目标外，还完成了若干扩展科学试验。CCD立体相机获得了月球虹湾地区的35轨空间分辨率约为1．3m的局域立体图像，以及7m空间分辨率、100％覆盖的全月立体图像，是迄今为止国际上分辨率最高、最清晰的全月立体图像。文章在简要介绍在轨图像获取情况的基础上，对15km／100km椭圆轨道及100km圆轨道上获取的图像进行了分析，重点讨论了拍摄时的太阳高度角对图像视觉效果以及图像信息量的影响，可为中国今后探测其他星球提供一定的参考。
