双目标定（Stereo Calibration）是在计算机视觉中用于确定双摄像头系统内外参数的过程。OpenCV库提供了用于双目标定的函数

#include <opencv2/opencv.hpp>
#include <opencv2/calib3d/calib3d.hpp>

int main() {
    // 读取双目标定的结果
    cv::FileStorage fs("stereo_calibration.yml", cv::FileStorage::READ);

    cv::Mat cameraMatrix1, distCoeffs1, cameraMatrix2, distCoeffs2, R, P1, P2, Q;
    fs["cameraMatrix1"] >> cameraMatrix1;
    fs["distCoeffs1"] >> distCoeffs1;
    fs["cameraMatrix2"] >> cameraMatrix2;
    fs["distCoeffs2"] >> distCoeffs2;
    fs["R"] >> R;
    fs["P1"] >> P1;
    fs["P2"] >> P2;
    fs["Q"] >> Q;
    fs.release();

    // 读取左右摄像头的图像
    cv::Mat imgLeft = cv::imread("left_image.jpg", cv::IMREAD_GRAYSCALE);
    cv::Mat imgRight = cv::imread("right_image.jpg", cv::IMREAD_GRAYSCALE);

    // 矫正图像
    cv::Mat imgRectLeft
