代码说明:

  共轭梯度法(Conjugate Gradient)是介于最速下降法与牛顿法之间的一个方法,它仅需利用一阶导数信息,但克服了最速下降法收敛慢的缺点,又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点,共轭梯度法不仅是解决大型线性方程组最有用的方法之一,也是解大型非线性最优化最有效的算法之一(Conjugate gradient method (Conjugate Gradient) is between the steepest descent method and Newton' s method between a method that takes only a first derivative information, but to overcome the slow convergence of the steepest descent method shortcomings, but also avoid the need to store Newton and computing the inverse Hesse matrix and disadvantages, conjugate gradient method is not only to solve large linear equations of the most useful methods, large-scale nonlinear optimization solution is the most efficient algorithms)

    利用PHOTOSHOP软件可以量测出左右像片各控制点的像素坐标,通过公式可以计算出其像点坐标。再根据给定的控制点的空间坐标,利用直线线性变换解法计算出11个DLT参数即l的系数值以及内方位元素然后解算出外方位元素。另外一种方式是用单像空间后方交会的公式计算出外方位元素。利用单像空间后方交会的来结算影像的外方位元素的基本思想是:以单幅影像为基础,从该影像所覆盖地面范围内若干控制点的已知地面坐标和相应点的像坐标量测值出发,根据共线条件方程,解求该影像在航空摄影时刻的外方位元素。首先建立单文档的程序,建立一个对话框类,在这个类中进行像素坐标、控制点坐标文件的打开与读取,然后利用DLT公式进行外方位元素的解算。 数据检核部分用前方交会算法来进行,首先根据ID找到左右片的像点的同名点,然后计算变换矩阵及系数,根据给定的内方位元素,利用公式解算出像点的控制点坐标,然后和给定的控制点坐标相比较即可进行精度评定。 (PHOTOSHOP software can be measured using a photo of the control points around the pixel coordinates can be calculated by the formula sit out the image point Standard. According to the given coordinates of control points, the use of straight-line method to calculate the linear transformation of 11 DLT parameters that the coefficient l Value and calculate the orientation elements of exterior orientation elements and solutions. Another way is to use a single formula as the calculation of space resection Orientation elements out. Use as space resection alone to settle the image exterior orientation is the basic idea: to single video As the basis of images from the ground covered by a number of control points within the known ground coordinates and image coordinates of corresponding points in the measured values , The realities of collinearity equation, find the image in the time of aerial photography exterior orientation elements.
