1.通过nuget安装OpenCvSharp4 ，下面四个都要安装否则会出现错误！

2.运行摄像头代码

windows_loaded中的代码

         Thread threadA = new Thread(run_cap);
            threadA.Start();

摄像头图像代码

        void run_cap()
        {
            Mat src = new Mat();
            FrameSource frame = Cv2.CreateFrameSource_Camera(0);
            while (true)
            {

                frame.NextFrame(src);

                System.Drawing.Bitmap bitmap = BitmapConverter.ToBitmap(src);

                
                Action action1 = () =>
                {
                    iCamera.Source = BitmapToBitmapImage(bitmap);
                };
                this.Dispatcher.BeginInvoke(action1);

            }

        }

bitmap to image 代码

        public System.Windows.Media.Imaging.BitmapImage BitmapToBitmapImage(System.Drawing.Bitmap bitmap)
        {
            MemoryStream ms = new MemoryStream();
            bitmap.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
            System.Windows.Media.Imaging.BitmapImage bit3 = new System.Windows.Media.Imaging.BitmapImage();
            bit3.BeginInit();
            bit3.StreamSource = ms;
            bit3.EndInit();
            return bit3;
        }

xaml文件中显示摄像头内容的Image控件

            <Grid Grid.Column="2">
                        <Image  x:Name="iCamera" Margin="0,0,0,0" Width="120"  Height="120" Source="Assets/Images/redo.png" VerticalAlignment="Top"/>
                
                    </Grid>
