遥感中，通过空间后方交会来求得像点坐标所对应的地面点坐标。本程序即实现空间后方交会，通过输入三个以上的像点坐标来进行平差之后求得地面点坐标。-Remote sensing, space resection to obtain the corresponding pixel coordinates of ground point coordinates. The procedures that achieve space resection, obtained after the adjustment is carried out by entering the coordinates of the image point in more than three ground point coordinates.
