noe*_*cus 7 c# camera winforms opencvsharp
我只想预览然后从 WinForms C# 应用程序中的设备摄像头(网络摄像头)捕获快照。
我用过这个:WebEye WebCameraControl,但它似乎在某些机器/相机上失败。描述暗示有更多的负载,但我在 NuGet 上找不到任何适用于 WinForms 的内容。
有什么建议吗?我觉得我错过了一些明显的东西,比如一个可以做到这一点的内置 Windows 控件!

试试OpenCVSharp。一些带有图片框和按钮的代码片段:
VideoCapture capture;
Mat frame;
Bitmap image;
private Thread camera;
bool isCameraRunning = 0;
private void CaptureCamera() {
camera = new Thread(new ThreadStart(CaptureCameraCallback));
camera.Start();
}
private void CaptureCameraCallback() {
frame = new Mat();
capture = new VideoCapture(0);
capture.Open(0);
if (capture.IsOpened()) {
while (isCameraRunning) {
capture.Read(frame);
image = BitmapConverter.ToBitmap(frame);
if (pictureBox1.Image != null) {
pictureBox1.Image.Dispose();
}
pictureBox1.Image = image;
}
}
}
private void button1_Click(object sender, EventArgs e) {
if (button1.Text.Equals("Start")) {
CaptureCamera();
button1.Text = "Stop";
isCameraRunning = true;
}
else {
capture.Release();
button1.Text = "Start";
isCameraRunning = false;
}
}
