将双目标定的calibration.xml文件写出来

要将双目标定的`calibration.xml`文件写出，你可以使用OpenCV的`FileStorage`类。下面是一个示例代码，演示如何将双目标定的结果写入`calibration.xml`文件：

#include <iostream>
#include <opencv2/opencv.hpp>

int main()
{
    // 定义标定参数和映射表
    cv::Mat Q, R, T;
    cv::Mat cameraMatrix1, cameraMatrix2;
    cv::Mat distCoeffs1, distCoeffs2;
    cv::Mat R1, R2, P1, P2;
    cv::Mat map1x, map1y, map2x, map2y;

    // 假设你已经完成了双目相机标定，得到了以上参数和映射表

    // 创建FileStorage对象，准备写入数据
    cv::FileStorage fs("calibration.xml", cv::FileStorage::WRITE);

    // 写入标定参数和映射表
    fs << "Q" << Q;
    fs << "R" << R;
    fs << "T" << T;
    fs << "cameraMatrix1" << cameraMatrix1;
    fs << "cameraMatrix2" << cameraMatrix2;
    fs << "distCoeffs1" << distCoeffs1;
    fs << "distCoeffs2" << distCoeffs2;
    fs << "R1" << R1;
    fs << "R2" << R2;
    fs << "P1" << P1;
    fs << "P2" << P2;
    fs << "map1x" << map1x;
    fs << "map1y" << map1y;
    fs << "map2x" << map2x;
    fs << "map2y" << map2y;

    // 关闭FileStorage对象
    fs.release();

    std::cout << "双目标定结果已保存至 calibration.xml 文件" << std::endl;

    return 0;
}

请注意，此示例中的标定参数和映射表是假设已经计算好的，你需要根据实际情况进行替换。

希望能对你有所帮助！
