摄影测量中的空间前方交会程序，采用的是matlab编写的点投影系数法和共线条件方程法，结合空间后方交会求解的双像外方位元素，可以进行待定点的三维坐标的求解。(The program of space intersection in photogrammetry, using the projection coefficient method and collinear equation method to prepare the MATLAB, combined with the space r

利用已知控制点，通过空间后方交会求得像片的外方位元素，并利用求得的外方位元素，通过前方交会求出像点的地面摄影测量坐标，并判断外方位元素的精度是否达标。(By using the known control points, the exterior orientation elements of the photo are obtained through the space resection. The ground photogrammetric coordinates of the imag
