次のコードに問題があります
namespace MyApp
{
public partial class PhotoWindow : Window
{
private Capture _capture;
public PhotoWindow ()
{
InitializeComponent();
_capture = new Capture();
if (_capture != null)
{
//<Image> in XAML
CaptureSource.Width = 150;
CaptureSource.Height = 180;
_capture.ImageGrabbed += ProcessFrame;
_capture.Start();
}
Activated += (s, e) => _capture.Start();
Closing += (s, e) =>
{
if (_capture == null) return;
_capture.Stop();
_capture.Dispose();
};
}
private void ProcessFrame(object sender, EventArgs e)
{
try
{
Image<Bgr, Byte> frame = _capture.RetrieveBgrFrame();
CaptureSource.Source = Helper.ToBitmapSource(frame);
}
catch (Exception exception)
{
System.Windows.MessageBox.Show(exception.ToString());
}
}
}
}
アプリケーションを実行すると、System.InvalidOperationException: The thread that this call can not access this object because the owner is another thread
オンラインで例外が発生しますCaptureSource.Source = Helper.ToBitmapSource(frame);
私はこれを解決できるので?
