CPPsimplex
单纯形法,求解线性规划问题的通用方法。单纯形是美国数学家G.B.丹齐克于1947年首先提出来的。它的理论根据是:线性规划问题的可行域是 n维向量空间Rn中的多面凸集,其最优值如果存在必在该凸集的某顶点处达到。顶点所对应的可行解称为基本可行解。单纯形法的基本思想是:先找出一个基本可行解,对它进行鉴别,看是否是最优解;若不是,则按照一定法则转换到另一改进的基本可行解,再鉴别;若仍不是,则再转换,按此重复进行。因基本可行解的个数有限,故经有限次转换必能得出问题的最优解。如果问题无最优解也可用此法判别。

DLT057
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。
