要求从键盘输入地面控制点坐标、对应像点坐标、立体像对的内方位元素和相对方位元素,用c++实现立体像对的绝对定向,输出7个绝对方位元素,要使用到类和构造函数,避免使用复杂库,并在每一行添加注释

单像空间后方交会程序 实现单张像片像点坐标及控制点坐标计算内外方位元素 可直接运行 结果同时写入txt文件
好的,我明白了,以下是实现代码和注释:
```c++
#include <iostream>
#include <cmath>
using namespace std;
class AbsoluteOrientation {
private:
double groundControlPoint[3]; // 地面控制点坐标
double correspondingImagePoint[3]; // 对应像点坐标
double internalOrientationElements[4]; // 立体像对的内方位元素
double relativeOrientationElements[6]; // 相对方位元素
public:
AbsoluteOrientation(double gcp[], double cip[], double ioe[], double roe[]) {
// 构造函数,初始化类的成员变量
for (int i = 0; i < 3; i++) {
groundControlPoint[i] = gcp[i];
correspondingImagePoint[i] = cip[i];
}
for (int i = 0; i < 4; i++) {
internalOrientationElements[i] = ioe[i];
}
for (int i = 0; i < 6; i++) {
relativeOrientationElements[i] = roe[i];
}
}
double* getAbsoluteOrientationElements() {
// 计算并返回绝对方位元素数组
double* absoluteOrientationElements = new double[7]; // 用于存储绝对方位元素的数组
double a = internalOrientationElements[0];
double b = internalOrientationElements[1];
double c = internalOrientationElements[2];
double d = internalOrientationElements[3];
double omega = relativeOrientationElements[0];
double phi = relativeOrientationElements[1];
double kappa = relativeOrientationElements[2];
double X0 = relativeOrientationElements[3];
double Y0 = relativeOrientationElements[4];
double Z0 = relativeOrientationElements[5];
// 计算旋转矩阵的元素
double cosOmega = cos(omega);
double sinOmega = sin(omega);
double cosPhi = cos(phi);
double sinPhi = sin(phi);
double cosKappa = cos(kappa);
double sinKappa = sin(kappa);
double r11 = cosPhi * cosKappa;
double r12 = sinOmega * sinPhi * cosKappa + cosOmega * sinKappa;
double r13 = -cosOmega * sinPhi * cosKappa + sinOmega * sinKappa;
double r21 = -cosPhi * sinKappa;
double r22 = -sinOmega * sinPhi * sinKappa + cosOmega * cosKappa;
double r23 = cosOmega * sinPhi * sinKappa + sinOmega * cosKappa;
double r31 = sinPhi;
double r32 = -sinOmega * cosPhi;
double r33 = cosOmega * cosPhi;
// 计算平移向量
double deltaX = groundControlPoint[0] - X0;
double deltaY = groundControlPoint[1] - Y0;
double deltaZ = groundControlPoint[2] - Z0;
// 计算物方坐标系的坐标
double x = r11 * deltaX + r12 * deltaY + r13 * deltaZ;
double y = r21 * deltaX + r22 * deltaY + r23 * deltaZ;
double z = r31 * deltaX + r32 * deltaY + r33 * deltaZ;
// 计算比例尺
double k = (a + b * x / z + c * y / z) / (1 + d * x / z + e * y / z);
// 计算绝对方位元素
absoluteOrientationElements[0] = x;
absoluteOrientationElements[1] = y;
absoluteOrientationElements[2] = z;
absoluteOrientationElements[3] = omega;
absoluteOrientationElements[4] = phi;
absoluteOrientationElements[5] = kappa;
absoluteOrientationElements[6] = k;
return absoluteOrientationElements;
}
};
int main() {
double gcp[3]; // 地面控制点坐标
double cip[3]; // 对应像点坐标
double ioe[4]; // 立体像对的内方位元素
double roe[6]; // 相对方位元素
// 从键盘输入地面控制点坐标、对应像点坐标、立体像对的内方位元素和相对方位元素
cout << "请输入地面控制点坐标:";
cin >> gcp[0] >> gcp[1] >> gcp[2];
cout << "请输入对应像点坐标:";
cin >> cip[0] >> cip[1] >> cip[2];
cout << "请输入立体像对的内方位元素:";
cin >> ioe[0] >> ioe[1] >> ioe[2] >> ioe[3];
cout << "请输入相对方位元素:";
cin >> roe[0] >> roe[1] >> roe[2] >> roe[3] >> roe[4] >> roe[5];
// 调用绝对定向类计算绝对方位元素
AbsoluteOrientation ao(gcp, cip, ioe, roe);
double* absoluteOrientationElements = ao.getAbsoluteOrientationElements();
// 输出绝对方位元素
cout << "绝对方位元素为:" << endl;
cout << "X: " << absoluteOrientationElements[0] << endl;
cout << "Y: " << absoluteOrientationElements[1] << endl;
cout << "Z: " << absoluteOrientationElements[2] << endl;
cout << "Omega: " << absoluteOrientationElements[3] << endl;
cout << "Phi: " << absoluteOrientationElements[4] << endl;
cout << "Kappa: " << absoluteOrientationElements[5] << endl;
cout << "k: " << absoluteOrientationElements[6] << endl;
// 释放动态分配的数组内存
delete[] absoluteOrientationElements;
return 0;
}
```
以上就是实现立体像对的绝对定向的 c++ 代码,类名为 AbsoluteOrientation,构造函数用于初始化类的成员变量,getAbsoluteOrientationElements() 方法用于计算绝对方位元素数组并返回,main() 函数用于读取用户输入并调用类的方法计算和输出绝对方位元素。
