Kinect SDK 2.0，映射骨架到圖像疊加？

Question

基本上我有一個相機流，我試圖覆蓋在相機流頂部的骨架，我可以成功地做到這一點如何骨架沒有正確地映射在流的頂部。

我嘗試過使用座標映射器，並將深度空間點改爲ColorSpacePoint，但是這會使骨架完全消失。

 #region Handling the body frame data arriving from the Sensor for Skeleton 
    /// Handles the body frame data arriving from the sensor 
    /// </summary> 
    /// <param name="sender">object sending the event</param> 
    /// <param name="e">event arguments</param> 
    private void Reader_FrameArrived(object sender, BodyFrameArrivedEventArgs e) 
    { 
     // Normal Boolean 
     bool dataReceived = false; 

     //Using = Provides a convenient syntax that ensures the correct use of IDisposable objects. 
     using (BodyFrame bodyFrame = e.FrameReference.AcquireFrame()) 
     { 
      //If from is not Null 
      if (bodyFrame != null) 
      { 
       //If body is not null 
       if (this.bodies == null) 
       { 
        //New body in array number of bodies 
        this.bodies = new Body[bodyFrame.BodyCount]; 
       } 

       // The first time GetAndRefreshBodyData is called, Kinect will allocate each Body in the array. 
       // As long as those body objects are not disposed and not set to null in the array, 
       // those body objects will be re-used. 
       bodyFrame.GetAndRefreshBodyData(this.bodies); 
       dataReceived = true; 
      } 
     } 

     //if Data has been recieved 
     if (dataReceived) 
     { 
      //Use Drawing Group 
      using (DrawingContext dc = this.drawingGroup.Open()) 
      { 
       // Draw a transparent background to set the render size 
       dc.DrawRectangle(Brushes.Transparent, null, new Rect(0.0, 0.0, this.displayWidth, this.displayHeight)); 

       //Set the index of the Pen to 0 
       int penIndex = 0; 

       //For each body 
       foreach (Body body in this.bodies) 
       { 
        //This is the colour of the Pen, It goes in array order for each body. 
        Pen drawPen = this.bodyColors[penIndex++]; 

        //If body is tracked 
        if (body.IsTracked) 
        { 
         this.DrawClippedEdges(body, dc); 

         IReadOnlyDictionary<JointType, Joint> joints = body.Joints; 

         // convert the joint points to depth (display) space 
         Dictionary<JointType, Point> jointPoints = new Dictionary<JointType, Point>(); 




         foreach (JointType jointType in joints.Keys) 
         { 


           // sometimes the depth(Z) of an inferred joint may show as negative 
           // clamp down to 0.1f to prevent coordinatemapper from returning (-Infinity, -Infinity) 
           CameraSpacePoint SkeletonPosition = joints[jointType].Position; 

           if (SkeletonPosition.Z < 0) 
           { 
            SkeletonPosition.Z = InferredZPositionClamp; 
           } 

           ColorSpacePoint colorSpacePoint = this.coordinateMapper.MapCameraPointToColorSpace(SkeletonPosition); 
           jointPoints[jointType] = new Point(colorSpacePoint.X/3.75, colorSpacePoint.Y/3.75); //Divide Positions by 3.8 to correctly map skeleton to canvas 

         } 



         //Draw the bodies with the Pen Colour selected on amount of bodies available 
         this.DrawBody(joints, jointPoints, dc, drawPen); 

         //Draw the Left Hand, Feeding in the State and type of Joint 
         this.DrawHand(body.HandLeftState, jointPoints[JointType.HandLeft], dc); 

         //Draw the right Hand, Feeding in the state and type of Joint 
         this.DrawHand(body.HandRightState, jointPoints[JointType.HandRight], dc); 

         this.test(joints, jointPoints, dc, drawPen, ElbowAngle); 
        } 
       } 

       // prevent drawing outside of our render area 
       this.drawingGroup.ClipGeometry = new RectangleGeometry(new Rect(0.0, 0.0, this.displayWidth, this.displayHeight)); 
      } 
     } 

正如你可以看到我嘗試使用ColorSpacePoint對關節的顏色流正常，但由於某種原因，這是行不通的映射，可有人善意解釋什麼即時做錯了什麼？

這裏是我的XAML的樣子：

好了，我看到你正在使用一個單獨的Image爲您的相機和你骨架;我利用DrawingGroup讓骨架和相機排隊。另外，我通常不會依靠Grid來放置我的Image - 我將所有東西都放在Canvas上，或者如果您確實需要Grid，請將兩個Image放在Grid的同一個單元中。

有關使用DrawingGroup的示例，請參閱this question。
