我是Kinect和VS Development的新手，我使用的是Windows Kinect Quickstart Series，但不幸的是，它适用于Kinect SDK v1.00。
我卡在了KinectColorView的使用上，我不能继续（我已经使用Googlin了2天了）。我也在StackOverflow上发现了这个非常相似的问题：Using KinectColorViewer in SDK1.5但无法解决我的问题。我知道我很亲密，但我需要帮助。
问题是：我无法让我的KinectColorViewer工作。
我将它添加到XAML设计器中，但似乎我无法将其绑定到SensorManager。 这是我的XAML代码：
<Window

</Grid>
</Window>
没有关于XAML代码的报告，除了我必须添加块
"KinectSensorManager="{Binding KinectSensorManager}"
，因为我无法通过XAML设计器的GUI找到解决方法（所以我对它的可行性有一些疑问）。
这是我的代码隐藏（我几乎完全复制了问题：Using KinectColorViewer in SDK1.5所以我无法理解为什么它不起作用!! ）
namespace KinectSetupDev
{
public partial class MainWindow : Window
{
// Automatically finds a Kinect for you.
private readonly KinectSensorChooser sensorChooser = new KinectSensorChooser();
public KinectSensorManager KinectSensorManager01 { get; private set; }
public MainWindow()

}

{
// Initialize the Kinect sensor manager.
KinectSensorManager01 = new KinectSensorManager();
KinectSensorManager01.KinectSensorChanged += this.KinectSensorChanged;
// Locate an available sensor.
sensorChooser.Start();
// Bind chooser's sensor value to the local sensor manager.
var kinectSensorBinding = new Binding("Kinect") { Source = this.sensorChooser };
BindingOperations.SetBinding(this.KinectSensorManager01, KinectSensorManager.KinectSensorProperty, kinectSensorBinding);
}
private void Window_Closed_1(object sender, EventArgs e)
{
UninitializeKinectServices(KinectSensorManager01.KinectSensor);
}
#region Kinect Discovery & Setup
private void KinectSensorChanged(object sender, KinectSensorManagerEventArgs<KinectSensor> args)
{
if (null != args.OldValue)
UninitializeKinectServices(args.OldValue);
if (null != args.NewValue)
InitializeKinectServices(KinectSensorManager01, args.NewValue);
}
// Kinect enabled apps should customize which Kinect services it initializes here.
private void InitializeKinectServices(KinectSensorManager kinectSensorManager, KinectSensor sensor)
{
// Application should enable all streams first.
kinectSensorManager.ColorStreamEnabled = true;
kinectSensorManager.DepthStreamEnabled = true;
kinectSensorManager.SkeletonStreamEnabled = true;
// Start the sensor!
try
{
sensor.Start();
sensorChooser.Kinect.ElevationAngle = 10;
tbMessages.Text = "Kinect Started";
}
catch (System.IO.IOException)
{
sensor = null;
tbMessages.Text = "Kinect Not Started" + "\r";
}
}
// Kinect enabled apps should uninitialize all Kinect services that were initialized in InitializeKinectServices() here.
private void UninitializeKinectServices(KinectSensor sensor)
{
if (sensor != null)
{
if (sensor.IsRunning)
{
sensorChooser.Kinect.ElevationAngle = 0;
sensor.Stop();
sensor.AudioSource.Stop();
}
}
}
#endregion Kinect Discovery & Setup
}
}
我尝试在构造函数中添加行DataContext = this;，但它不起作用。
应用程序运行，我的Kinect启动但KinectColorViewer没有显示任何内容。
此外，任何人都可以区分 sensor.SkeletonStream.Enable();
和 kinectSensorManager.SkeletonStreamEnabled = true; ??

在您的XAML中绑定到KinectSensorManager，该KinectSensorManager01不存在。您在代码中将其称为sensor.SkeletonStream.Enabled()，因此您需要在XAML中正确反映它。
这可能会解决它。但我看到的另一件事是你至少以3种不同的方式访问传感器。这就是你的第二个问题。
你正在对kinectSensorManager.SkeletonStreamEnabled = true和KinectSensorManager做同样的事情，你只是以不同的方式去做。 InitializeKinectServer是一个围绕Kinect硬件的数据模型，它可以为您管理许多平凡的小事。如果您打算使用它（我个人一直都在这样做），那么您应该始终使用它来访问硬件。这将确保您的参考永远不会失去同步。
因此，在您的sensor.Start()函数中，您不希望使用sensorChooser.Kinect.ElevationAngle和KinectSensorManager。您希望使用相应的<Window x:Class="SimpleKinectStart.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

KinectSensorManager使用kinectSensorManager.ElevationAngle时，您总是希望尽可能使用传感器管理器提供的包装。因此，您希望在init函数中使用KinectSensorManager.ElevationAngle，或在其他地方使用UninitializeKinectServices（注意本地调用与全局调用之间的差异）。这允许传感器管理器尝试执行您所要求的操作，并在需要时优雅地失败。
在KinectSensorChooser功能中，您只能直接处理传感器。当您点击此功能时，null选择了新的Kinect或丢失了它并将传感器设置为KinectSensorManager。您正在处理此函数中的旧传感器值，清理曾经链接到它的服务。您对null的任何引用都将是新传感器或{{1}}引用。

我手动添加了Path属性，它适用于我：
<WpfViewers:KinectColorViewer HorizontalAlignment="Left" Height="221" Margin="75,84,0,0" VerticalAlignment="Top" Width="372" Kinect="{Binding ElementName=kinectSensorChooser1, Mode=OneWay,Path=Kinect}"/>
