The lunar surface topography mapping is the basic work of the lunar exploration and plays an important role in the three-phase ("around-fall-back") lunar exploration program. In the "around" phase, it is necessary to use the camera carried by the spacecraft to acquire high-resolution image of area around the drop-off point. Due to the low orbit altitude and the limited field of view of camera, the width of the imagery obtained by the lunar satellite is relatively small compared to the range of the required drop-off area. Multiple strips stitching is an effective and practical way to solve larg...
