Kinect Couleur du corps

Question

Je vous écris une application qui nécessite la suppression de fond (où le joueur est), et masquer le corps de l'utilisateur avec une couleur ou un caractère (comme https://stackoverflow.com/questions/10599658/how-to-create-kinect-avatar).
Merci à l'avance

Le tutoriel à Channel 9, même si l'ancien est en version bêta 2, est facile à convertir. Voici le code final (converti)

public static class KinectExtensions 
    { 
     public static WriteableBitmap CreateLivePlayerRenderer(this KinectSensor sensor) 
     { 
      if (sensor.DepthStream.FrameWidth == 0) 
       throw new InvalidOperationException("Either open the depth stream before calling this method or use the overload which takes in the resolution that the depth stream will later be opened with."); 
      return CreateLivePlayerRenderer(sensor, sensor.DepthStream.FrameWidth, sensor.DepthStream.FrameHeight); 
     } 

     public static WriteableBitmap CreateLivePlayerRenderer(this KinectSensor sensor, int depthWidth, int depthHeight) 
     { 
      AllFramesReadyEventArgs d = new AllFramesReadyEventArgs(); 
      using (DepthImageFrame depthImage = d.OpenDepthImageFrame()) 
      { 
       WriteableBitmap target = new WriteableBitmap(depthWidth, depthHeight, 96, 96, PixelFormats.Bgra32, null); 
       var depthRect = new System.Windows.Int32Rect(0, 0, depthWidth, depthHeight); 

       sensor.DepthFrameReady += (s, e) => 
       { 
        Debug.Assert(depthImage.Height == depthHeight && depthImage.Width == depthWidth); 
       }; 

       sensor.ColorFrameReady += (s, e) => 
       { 
        // don't do anything if we don't yet have a depth image 
        DepthImageFrame colorImage = depthImage; 
        if (colorImage.BytesPerPixel == null) return; 

        byte[] color = new byte[sensor.ColorStream.FramePixelDataLength]; 
        e.OpenColorImageFrame().CopyPixelDataTo(color); 

        byte[] output = new byte[depthWidth * depthHeight * 4]; 

        // loop over each pixel in the depth image 
        int outputIndex = 0; 
        for (int depthY = 0, depthIndex = 0; depthY < depthHeight; depthY++) 
        { 
         for (int depthX = 0; depthX < depthWidth; depthX++, depthIndex += 2) 
         { 
          short[] bits = new short[colorImage.BytesPerPixel]; 
          depthImage.CopyPixelDataTo(bits); 
          // combine the 2 bytes of depth data representing this pixel 
          short depthValue = (short)(bits[depthIndex] | (bits[depthIndex + 1] << 8)); 

          // extract the id of a tracked player from the first bit of depth data for this pixel 
          int player = bits[depthIndex] & 7; 

          // find a pixel in the color image which matches this coordinate from the depth image 
          int colorX, colorY; 
          ColorImagePoint colorPoint = depthImage.MapToColorImagePoint(depthImage.Width, depthImage.Height, sensor.ColorStream.Format); 


          // ensure that the calculated color location is within the bounds of the image 
          colorX = colorPoint.X; 
          colorY = colorPoint.Y; 

          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 0]; 
          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 1]; 
          output[outputIndex++] = color[(4 * (colorX + (colorY * e.OpenColorImageFrame().Width))) + 2]; 
          output[outputIndex++] = player > 0 ? (byte)255 : (byte)0; 
         } 
        } 
        target.WritePixels(depthRect, output, depthWidth * PixelFormats.Bgra32.BitsPerPixel/8, 0); 
       }; 
       return target; 
      } 
     } 
    } 

Et ma réponse à https://stackoverflow.com/questions/10599658/how-to-create-kinect-avatar/10600919#10600919 explique comment créer le caractère. Bonne chance! J'espère que cela t'aides!
