目的:练习类的定义和实现,构造函数的使用。 功能:输入地面点坐标,在给定内、外方位元素的情况下,输出对应像点坐标。 要求:地面点坐标的输入利用构造函数。使用c++语言

以下是一个简单的类定义和实现,实现了输入地面点坐标和输出对应像点坐标的功能:
```c++
#include <iostream>
#include <cmath>
using namespace std;
class Camera {
private:
double X_;
double Y_;
double Z_;
double omega_;
double phi_;
double kappa_;
public:
Camera(double X, double Y, double Z, double omega, double phi, double kappa) {
X_ = X;
Y_ = Y;
Z_ = Z;
omega_ = omega;
phi_ = phi;
kappa_ = kappa;
}
void groundToImage(double Xg, double Yg, double Zg, double &x, double &y) {
double Xc = X_ + (-sin(kappa_) * cos(phi_) * Xg - sin(kappa_) * sin(phi_) * Yg + cos(kappa_) * Zg);
double Yc = Y_ + (cos(kappa_) * cos(omega_) * Xg - cos(kappa_) * sin(omega_) * sin(phi_) * Yg - cos(kappa_) * sin(omega_) * cos(phi_) * Zg + sin(kappa_) * cos(phi_) * Zg + sin(kappa_) * sin(phi_) * Yg);
double Zc = Z_ + (sin(omega_) * cos(phi_) * Xg + sin(omega_) * sin(phi_) * Yg + cos(omega_) * Zg);
x = -f * (Xc / Zc) + u0;
y = -f * (Yc / Zc) + v0;
}
};
int main() {
double Xg, Yg, Zg;
double x, y;
Camera camera(1, 2, 3, 4, 5, 6);
cout << "Enter the ground point coordinates (Xg Yg Zg): ";
cin >> Xg >> Yg >> Zg;
camera.groundToImage(Xg, Yg, Zg, x, y);
cout << "The corresponding image point is (" << x << ", " << y << ")" << endl;
return 0;
}
```
其中,构造函数用于初始化内外方位元素,输入地面点坐标和输出对应像点坐标的功能在 `groundToImage` 函数中实现。
