OpenCV 双目相机录制的视频，左右图像分割

双目相机输出将左右摄像头拼接在一起输出

思路：

• 拿opencv读取视频每一帧（33ms）
• 拿Rect分割一下就好了
• 将left right图像保存到不同文件(这里我将提前保存好的时间戳与采集的图像一一对应起来)

不多bibi直接上代码

    std::string timeStampesPath = argv[1];
    std::FILE * file;
    std::cout << timeStampesPath  << endl;
    file = std::fopen((timeStampesPath ).c_str(),"r");
    if(file == NULL){
        printf("cannot find file : %s \n" , timeStampesPath.c_str());
        return 0;
    }

    std::vector<long> imageTimeList;
    long nanosec;
    char string_Temp[60];
    // for (int i = 0 ; i < 1 ; i++){
