opencv storage 操作C++

读取

    FileStorage fs;
    fs.open("caliResult.xml",FileStorage::READ);

    int cameraId;
    Mat intrMatrix(3,3,CV_64F);
    Mat distCoeffs(5,1,CV_64F);

    fs["cameraId"]>>cameraId;//下面还有子节点，data 行列等信息，这个读取方式就不用一步一步的读取了
    fs["intrinsic_parameters"]>>intrMatrix;
    fs["distortion_parametes"]>>distCoeffs;

    fs.release();
