Global lunar mapping is one of the four basic objectives of Chang'E program on the first phase. A unified lunar control network is needed for high-precision mapping of the lunar surface. The positioning of high-precision control points on lunar surface images is of crucial importance for the set-up of lunar control network. The authors reviewed the existing lunar control networks, listed the high-precision control points with coordinate and accuracy, and located the most accurate five control points-laser ranging retro reflectors on Chang'E-1 and Chang'E-2 level-02 images. The processing fully utilized the common features between the LRO and Chang'E images, as well as the relative geometry among craters around lunar modules. With the geometric positioning and image correction method, location of these control points on image achieved an accuracy of about one pixel. The positioning of high-precision control points on Chang'E images can provide absolute position reference for the establishment of China's lunar control network.%全月制图是嫦娥一期工程4个基本目标之一.实现高精度月面制图需要建立一个统一的月面控制网,高精度控制点在嫦娥影像上的定位对于月面控制网的建立有着至关重要的意义.分析了现有月面控制网的基本情况及高精度月面控制点位置与精度,确定了落月舱及精度最高的5个棱镜控制点在嫦娥一号和嫦娥二号月球02级原始影像上的位置.定位过程充分利用落月舱在LRO和嫦娥影像上的共同特征,及落月舱局部区域月面环形坑的相对位置关系.通过几何定位与影像纠正的方法确定了控制点的图上位置,达到了约1个像素的定位精度.
