说明：  该程序实现了摄影测量学中的空间前方交会，即利用像片点坐标求出对应点坐标。用户只要将原始文件夹里的内容更改就可以利用该程序求出想要的数据了。
(Procedures for the implementation of the photogrammetry study space forward intersection, which coordinates the use of image point coordinates of corresponding points are obtained. As long as the original user folder changed the contents of the program can be obtained using the data you want.)
