将一个Kinect与两个窗口一起使用

Question

I am a very newbie on WPF, C#, and Kinect. But I've found out how to initialize the kinect, and show two windows. My application is a toy one, have a full screen app with a button, when the user clicks, it should open a new window.

I've tried but two things won't work:

• when the new window open the kinect user view won't show any body
• when closing the window (going back to the main) the app crashes

The prototype window XAML is like this:

<Window ...>
   <k:KinectRegion Name="region_">
      <Grid>
         <k:KinectUserView .../>
      </Grid>
   </k:KinectRegion>
</Window>

On the C# side, I have a prototype class like this:

public partial class MainWindow : Window
{
   public KinectSensor sensor_ = KinectSensor.GetDefault();

   public MainWindow()
   {
      //...
      KinectRegion.SetKinectRegion(this, region_);
      this.sensor_.Open();
   }
}

The secondary page (with identical constructor as above) has a button that calls a function that basically says sensor_.Close() and this.Close() .

Can I use a single kinect with multiple windows? In case not (please tell me I can!) how can I proceed in having two "views"? Pages AFAIK reading on the web, requite NavigationWindow , and VS complains I cannot add the kinect region to that.

Thanks!

It turns out you don't need to close the sensor . In order to make more windows work with one sensor:

• pass the KinectSensor initialized in the main one to the "child" window
• initialize the child's region

You just need to this.Close() without ever opening again the stream or closing it. The Kinect user view works flawlessly.
