我目前正在使用此代码来分析网络摄像头帧:

int main()
{
    VideoCapture cap(0); // open the default camera
    if (!cap.isOpened())  // check if we succeeded
        return -1;
    cap.set(CV_CAP_PROP_FPS, 15);

    std::vector<cv::Mat> images(9000);
    for (framenumb = 0; framenumb < 9000; ++framenumb) 
    {
        images[framenumb].create(480, 640, CV_8UC3);
    }
    for (framenumb = 0; framenumb < 9000; ++framenumb)
    {
        Mat frame;
        cap >> frame;
        if (frame.empty()) break; // end of video stream
        if (waitKey(1) == 27) break; // stop capturing by pressing ESC 
        frame.copyTo(images[framenumb]);
        imshow("webcam", images[framenumb]);
    }
    //We can then process the captured …
