您可以使用以下代码制作应用程序以捕获和显示video流：

public class CameraCapture { private Capture capture; //takes images from camera as image frames private bool captureInProgress; private void ProcessFrame(object sender, EventArgs arg) { Image ImageFrame = capture.QueryFrame(); //line 1 CamImageBox.Image = ImageFrame; //line 2 } private void Form1_Load(object sender, EventArgs e) { if (capture == null) { try { capture = new Capture(); } catch (NullReferenceException excpt) { MessageBox.Show(excpt.Message); } } 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; } } } 

不确定你想要对数据做什么，但是这将从相机中获得一个帧（并在WinForm上的pictureBox中显示）

 private void Form1_Load(object sender, EventArgs e) { var capture = new Emgu.CV.Capture(); using (var nextFrame = capture.QueryFrame()) { if (nextFrame != null) { pictureBox1.Image = nextFrame.ToBitmap(); } } }
