Kinect 用の単純なアプリケーションを 1 つ持っていますが、多くのリソースを消費しているようです。1〜2分間は正常に動作し、その後ラグが耐えられなくなります.
これは私の構成です：
インテル Core i3 CPU M330 2.13 GHz
4GBのRAM
ATI Radeon HD 4570
これは、アプリケーション ウィンドウのコードです。
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
Loaded += MainWindow_Loaded;
}
void MainWindow_Loaded(object sender, RoutedEventArgs e)
{
this.WindowState = System.Windows.WindowState.Maximized;
}
private void StopKinect(KinectSensor sensor)
{
if (sensor != null)
{
if (sensor.IsRunning)
{
//stop sensor
sensor.Stop();
//stop audio if not null
if (sensor.AudioSource != null)
{
sensor.AudioSource.Stop();
}
}
}
}
private void Window_Closing_1(object sender, System.ComponentModel.CancelEventArgs e)
{
StopKinect(Generics.GlobalKinectSensorChooser.Kinect);
}
}
これはメイン メニュー (最初の画面) のコードです。
public partial class MainMenu : Page
{
#region "Kinect"
private KinectSensorChooser sensorChooser;
#endregion
public MainMenu()
{
this.InitializeComponent();
if (Generics.GlobalKinectSensorChooser == null)
{
// initialize the sensor chooser and UI
this.sensorChooser = new KinectSensorChooser();
this.sensorChooser.KinectChanged += SensorChooserOnKinectChanged;
this.sensorChooserUi.KinectSensorChooser = this.sensorChooser;
this.sensorChooser.Start();
Generics.GlobalKinectSensorChooser = this.sensorChooser;
}
else
{ // initialize the sensor chooser and UI
this.sensorChooser = new KinectSensorChooser();
this.sensorChooser = Generics.GlobalKinectSensorChooser;
this.sensorChooser.KinectChanged += SensorChooserOnKinectChanged;
this.sensorChooserUi.KinectSensorChooser = sensorChooser;
}
// Bind the sensor chooser's current sensor to the KinectRegion
var regionSensorBinding = new Binding("Kinect") { Source = this.sensorChooser };
BindingOperations.SetBinding(this.kinectRegion, KinectRegion.KinectSensorProperty, regionSensorBinding);
}
private void SensorChooserOnKinectChanged(object sender, KinectChangedEventArgs args)
{
bool error = false;
if (args.OldSensor != null)
{
try
{
args.OldSensor.DepthStream.Range = DepthRange.Default;
args.OldSensor.SkeletonStream.EnableTrackingInNearRange = false;
args.OldSensor.DepthStream.Disable();
args.OldSensor.SkeletonStream.Disable();
args.OldSensor.ColorStream.Disable();
}
catch (InvalidOperationException)
{
// KinectSensor might enter an invalid state while enabling/disabling streams or stream features.
// E.g.: sensor might be abruptly unplugged.
error = true;
}
}
if (args.NewSensor != null)
{
try
{
args.NewSensor.DepthStream.Enable(DepthImageFormat.Resolution640x480Fps30);
args.NewSensor.ColorStream.Enable(ColorImageFormat.RgbResolution640x480Fps30);
args.NewSensor.SkeletonStream.Enable();
}
catch (InvalidOperationException)
{
error = true;
}
}
if (!error)
kinectRegion.KinectSensor = args.NewSensor;
}
private void Screen1ButtonOnClick(object sender, RoutedEventArgs e)
{
this.sensorChooser.KinectChanged -= SensorChooserOnKinectChanged;
(Application.Current.MainWindow.FindName("_mainFrame") as Frame).Source = new Uri("Depth.xaml", UriKind.Relative);
}
}
そして、この screen1 のコード:
public partial class Depth : Page
{
#region "Kinect"
private KinectSensorChooser sensorChooser;
#endregion
const float MaxDepthDistance = 4095; // max value returned
const float MinDepthDistance = 850; // min value returned
const float MaxDepthDistanceOffset = MaxDepthDistance - MinDepthDistance;
public Depth()
{
this.InitializeComponent();
// initialize the sensor chooser and UI
this.sensorChooser = new KinectSensorChooser();
//Assign the sensor chooser with the sensor chooser from the mainwindow.
//We are reusing the sensorchoosing declared in the first window that can in contact with kinect
this.sensorChooser = Generics.GlobalKinectSensorChooser;
//subscribe to the sensorChooserOnKinectChanged event
this.sensorChooser.KinectChanged += SensorChooserOnKinectChanged;
//Assign Kinect Sensorchooser to the sensorchooser we got from our static class
this.sensorChooserUi.KinectSensorChooser = sensorChooser;
// Bind the sensor chooser's current sensor to the KinectRegion
var regionSensorBinding = new Binding("Kinect") { Source = this.sensorChooser };
BindingOperations.SetBinding(this.kinectRegion, KinectRegion.KinectSensorProperty, regionSensorBinding);
}
private void SensorChooserOnKinectChanged(object sender, KinectChangedEventArgs args)
{
bool error = false;
if (args.OldSensor != null)
{
try
{
args.OldSensor.DepthStream.Range = DepthRange.Default;
args.OldSensor.SkeletonStream.EnableTrackingInNearRange = false;
args.OldSensor.DepthStream.Disable();
args.OldSensor.SkeletonStream.Disable();
args.OldSensor.ColorStream.Disable();
}
catch (InvalidOperationException)
{
error = true;
}
}
if (args.NewSensor != null)
{
try
{
args.NewSensor.DepthStream.Enable(DepthImageFormat.Resolution640x480Fps30);
args.NewSensor.ColorStream.Enable(ColorImageFormat.RgbResolution640x480Fps30);
args.NewSensor.SkeletonStream.Enable();
}
catch (InvalidOperationException)
{
error = true;
}
}
if (!error)
kinectRegion.KinectSensor = args.NewSensor;
}
private void MenuButtonOnClick(object sender, RoutedEventArgs e)
{
//Unsubscribe to the sensorchooser's event SensorChooseronkinectChanged
this.sensorChooser.KinectChanged -= SensorChooserOnKinectChanged;
(Application.Current.MainWindow.FindName("_mainFrame") as Frame).Source = new Uri("MainScreen.xaml", UriKind.Relative);
}
}
さらにいくつかの画面があります。WpfViewers の KinectDepthViewer を使用しているこの画面を選択しました。この画面のラグは最悪で、アプリケーションはほぼ瞬時に使用できなくなります。ボタンしかない他の画面では、最初はラグがありませんが、2〜3分使用するとラグが発生します。
おそらく初期化で何か間違ったことをしているのかわかりません。誰かがアドバイスをくれることを願っています。私は、人々がより弱い構成での開発に問題を抱えていなかったと読んだので、それが原因ではないことを願っています.
ありがとうございました！
