    // 1、准备文件写操作
    FileStorage fs("F:/C++/2. OPENCV 3.1.0/TEST/test.txt", FileStorage::WRITE);
    
    // 2、开始文件写入
    fs << "frameCount" << 5;
    
    // 3、写入时间
    time_t rawtime;  // 64-bit time value
    time(&rawtime);
    fs << "calibrationDate" << asctime(localtime(&rawtime));
    
    // 4、写入矩阵
