我是Kinect和VS Development的新手，我使用的是Windows Kinect Quickstart Series，但不幸的是，它是针对Kinect SDK v1.00的。
我对KinectColorView的使用感到困惑，我无法继续（我已经Googlin呆了2天了）。我也发现了一个非常相似的问题：Using KinectColorViewer in SDK1.5在StackOverflow上，但无法解决我的问题。我知道我已经接近了，但是我需要帮助。
问题是：我无法使KinectColorViewer正常工作。
我将其添加到XAML设计器中，但似乎无法将其绑定到SensorManager。
这是我的XAML代码：
<Window

</Grid>
</Window>
没有什么可报告的XAML代码，除了我必须添加块
"KinectSensorManager="{Binding KinectSensorManager}"
在KinectColorViewer项目中通过编写它来完成，因为我无法通过XAML设计器的GUI找到解决方法（因此我对它的可行性有些怀疑）。
这是我的后台代码（我几乎完全复制了以下问题：Using KinectColorViewer in SDK1.5，所以我不明白为什么它不起作用！）
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()
{
InitializeComponent();
DataContext = this;
}
private void Window_Loaded_1(object sender, RoutedEventArgs e)
{
// 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
}
}
我试图在构造器中添加行
DataContext = this;，但是它不起作用。应用程序运行，我的Kinect启动，但KinectColorViewer却什么也没显示。
而且，谁能说出
sensor.SkeletonStream.Enable();之间的区别和
kinectSensorManager.SkeletonStreamEnabled = true; ?? 最佳答案
在您的XAML中，您绑定到不存在的KinectSensorManager。您在代码中将其称为KinectSensorManager01，因此需要在XAML中正确反映出来。
那可能会解决它。但是我看到的另一件事是，您以至少3种不同的方式访问传感器。这是您的第二个问题。
您使用sensor.SkeletonStream.Enabled()和kinectSensorManager.SkeletonStreamEnabled = true做相同的事情，只是以不同的方式进行。 KinectSensorManager是包裹在Kinect硬件周围的数据模型，它可以为您管理许多平凡的小事情。如果要使用它（我一直都在使用），则应始终使用它来访问硬件。这将确保您的引用不会永不同步。
因此，在您的InitializeKinectServer函数中，您不想使用sensor.Start()和sensorChooser.Kinect.ElevationAngle。您要使用相应的KinectSensorManager调用。
这是一个快速肮脏的应用程序，仅显示KinectColorChooser：

在使用
KinectSensorManager时，您总是尽可能使用传感器管理器提供的包装纸。因此，您可能想在init函数中使用kinectSensorManager.ElevationAngle，或在其他地方使用KinectSensorManager.ElevationAngle（请注意本地调用与全局调用之间的区别）。这使传感器管理器可以尝试执行您要求的操作，并在需要时适当地失败。在
UninitializeKinectServices功能中，您将只能直接处理传感器。按下此功能时，KinectSensorChooser选择了新的Kinect或丢失了它，并将传感器设置为null。您正在使用此功能处理旧的传感器值，从而清理了曾经与之链接的服务。您对KinectSensorManager所做的任何引用都将是新传感器或null引用。
