该源码的功能是利用用户的输入地面控制点和影像点坐标，利用最小二乘法思想最终迭代出影像的外方位元素，即摄影测量中的单幅影像后方交会。程序关键部分是在VS2010下，利用自定义的矩阵类实现的，能很好的体现出面向对象的思想。-The source function is the use of user input ground control points and image point coordinates, least-squares method using the final iteration of the ideological image of the exterior orientation elements, namely the single-image photogrammetric resection. Key part of the program in VS2010, using a custom matrix class implementation, can well reflect the object-oriented thinking.
