如何将EMGU相机捕获图像保存在文件夹中并检索

我使用了emguCV的ImageBox而不是原生C#的pictureBox，并在表单上添加了一个按钮btnSave

namespace CameraCapture
{
    public partial class CameraCapture : Form
    {
        //declaring global variables
        private Capture capture;        //takes images from camera as image frames
        private bool captureInProgress;
        private bool saveToFile;
        public CameraCapture()
        {
            InitializeComponent();
        }
        //------------------------------------------------------------------------------//
        //Process Frame() below is our user defined function in which we will create an EmguCv 
        //type image called ImageFrame. capture a frame from camera and allocate it to our 
        //ImageFrame. then show this image in ourEmguCV imageBox
        //------------------------------------------------------------------------------//
        private void ProcessFrame(object sender, EventArgs arg)
        {
            Image<Bgr, Byte> ImageFrame = capture.QueryFrame();
            CamImageBox.Image = ImageFrame;
            if (saveToFile)
            {
                ImageFrame.Save(@"D:'MyPic.jpg");
                saveToFile = !saveToFile;
            }
        }
        //btnStart_Click() function is the one that handles our "Start!" button' click 
        //event. it creates a new capture object if its not created already. e.g at first time
        //starting. once the capture is created, it checks if the capture is still in progress,
        //if so the
        private void btnStart_Click(object sender, EventArgs e)
        {
            #region if capture is not created, create it now
            if (capture == null)
            {
                try
                {
                    capture = new Capture();
                }
                catch (NullReferenceException excpt)
                {
                    MessageBox.Show(excpt.Message);
                }
            }
            #endregion
            if (capture != null)
            {
                if (captureInProgress)
                {  //if camera is getting frames then stop the capture and set button Text
                    // "Start" for resuming capture
                    btnStart.Text = "Start!"; //
                    Application.Idle -= ProcessFrame;
                }
                else
                {
                    //if camera is NOT getting frames then start the capture and set button
                    // Text to "Stop" for pausing capture
                    btnStart.Text = "Stop";
                    Application.Idle += ProcessFrame;
                }
                captureInProgress = !captureInProgress;
            }
        }
        private void ReleaseData()
        {
            if (capture != null)
                capture.Dispose();
        }
        private void btnSave_Click(object sender, EventArgs e)
        {
            saveToFile = !saveToFile;
        }
    }
}

这个主题很旧，但如果你想使用emguCV的ImageBox，你可以使用这段代码

   private void ProcessFrame(object sender, EventArgs arg)
    {
        Mat frame = new Mat();
        capture.Retrieve(frame);
        CamImageBox.Image = frame;
    }
