WPF kinectアプリケーションで画像のRGBデータ「カラーストリーム」のストリームを表示したいのですが、どうすればよいですか？

ありがとう

これが私のコードとxamlです。スケルトンが画像に描画されていることがわかります。必要なのは、スケルトンのほかに画像にカラーストリームを追加することです。これを行うにはどうすればよいですか？

どうもありがとう、

Microsoftのサンプルを試しましたか？またはインターネットサンプル（そこにはたくさんあります）

C＃で開発しているので、WPFとSDK1.0（またはそれ以上）を使用していると仮定します。

これが1つの解決策です：

最初にカラーストリームを有効にします。

 KinectSensor kinectSensor = KinectSensor.KinectSensors[0];
 kinectSensor.ColorStream.Enable(ColorImageFormat.RgbResolution640x480Fps30);
 kinectSensor.Start();
 kinectSensor.ColorFrameReady += this.ColorImageReady;

次に、イベントを処理します。

    private static readonly int Bgr32BytesPerPixel = (PixelFormats.Bgr32.BitsPerPixel + 7) / 8;
    private byte[] pixelData;
    private WriteableBitmap CameraSource;

private void ColorImageReady(object sender, ColorImageFrameReadyEventArgs e)
        {
           bool receivedData = false;
            using (ColorImageFrame imageFrame = e.OpenColorImageFrame())
            {
                if (imageFrame != null)
                {

                    if (pixelData == null)
                    {
                        this.pixelData = new byte[imageFrame.PixelDataLength];
                    }

                    imageFrame.CopyPixelDataTo(this.pixelData);
                    receivedData = true;

                    // A WriteableBitmap is a WPF construct that enables resetting the Bits of the image.
                    // This is more efficient than creating a new Bitmap every frame.
                    if (receivedData)
                    {


                    this.CameraSource.WritePixels(
                        new Int32Rect(0, 0, imageFrame.Width, imageFrame.Height),
                        this.pixelData,
                        imageFrame.Width * Bgr32BytesPerPixel,
                        0);
                    }

                }
            }
        }

xamlで：

 <Image Name="Camera" Width="160" Height="120" Margin="0,0,0,0"  RenderOptions.BitmapScalingMode="HighQuality" />

コードビハインド：

kinectSensor.ColorFrameReady += new EventHandler<Microsoft.Kinect.ColorImageFrameReadyEventArgs>(ColorImageFrameReady_handler);

および対応するハンドラー：

public void ColorImageFrameReady_handler(object sender, Microsoft.Kinect.ColorImageFrameReadyEventArgs e)
        {
            Camera.Source = CameraSource;
        }
