美好的一天eh。「終止」一個類的實例
我正在研究一個C＃項目，我們使用Microsoft Kinect，使用它來跟蹤執行一系列跳轉的人員，並生成計算膝蓋角度的骨架。
昨天晚上當我們測試主題時，我認爲可以很好地控制程序，您可以點擊並結束「當前」測試主題的輸出文件，然後啓動另一個主題。爲了跟蹤骨架，我們創建了Kinect for Windows SDK中的Tracker類跟蹤器對象。然後啓動所有跟蹤和輸出的邏輯。但是，當我們「關閉」第一個主題的輸出時，我們似乎只關閉文件，而不是跟蹤器對象的實際實例。這會導致跟蹤器保持「打開」狀態，並與我們爲新測試主體創建的跟蹤器對象的新實例一起存在，同時使用雙倍的計算資源並造成不可接受的性能下降。
如何「關閉」跟蹤器對象的第一個實例？
如果你們需要檢查代碼，請告訴我;我沒有包括它，因爲在這裏發佈是不切實際的。
編輯：
這裏至少有一些代碼。我們有「開始」事件（針對第一個測試主題），「下一個主題」事件（針對後續測試主題）以及「跟蹤器」代碼。
下個主題：（這是一個我們需要進行更改）
/// <summary>
/// stops "old" file and graph streams, closes file, launches dialog for new subject and starts
/// stream up again
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void buttonNextSubject_Click(object sender, RoutedEventArgs e)
{
//Ask the user if they're sure they want to stop the current stream
if (MessageBox.Show("Are you sure you want to stop the stream and start a new one?", "New Subject", MessageBoxButton.OKCancel) == MessageBoxResult.OK){
if (fileCheck == true)
{
tracker.outputFile.closeFiles();
//SHUT DOWN OLD TRACKER HERE
}
else
{
return;
}
}
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "Subject"; //Default file name
dlg.DefaultExt = ".txt"; //Default file extension
dlg.Filter = "Text documents (.txt)|*.txt"; //Filter files by extension
//Show save file dialog box
Nullable<bool> result = dlg.ShowDialog();
buttonStart.IsEnabled = false;
buttonPause.IsEnabled = true;
buttonResume.IsEnabled = false;
fileCheck = true;
//Start Kinect- If no sensor, ask to connect one and exit.
try
{
this.sensor.Start();
}
catch (IOException)
{
this.sensor = null;
//display error message here
MessageBox.Show("No Kinect sensor found. Please connect one and restart the application", "*****ERROR*****");
}
sensor.ElevationAngle = 0;
tracker = new Tracker(sensor, this, dlg.FileName);
}
}
的跟蹤對象/跟蹤器類：
internal class Tracker{
private Skeleton[] skeletons = null;
private MainWindow window;
public Class1 outputFile;
public string fn;
public Tracker(KinectSensor sensor, MainWindow win, string fileName){
//Connect the skeleton frame handler and enable skeleton tracking
sensor.SkeletonFrameReady += SensorSkeletonFrameReady;
sensor.SkeletonStream.Enable();
sensor.ColorFrameReady += SensorColorFrameReady;
sensor.ColorStream.Enable();
window = win;
outputFile = new Class1(fileName);
fn = fileName;
window.graphTickPen2.DashStyle = System.Windows.Media.DashStyles.Dash;
}
最後，在「開始」事件，我基於「Next Subject」事件關閉：
private void buttonStart_Click(object sender, RoutedEventArgs e){
// Configure save file dialog box
Microsoft.Win32.SaveFileDialog dlg = new Microsoft.Win32.SaveFileDialog();
dlg.FileName = "Default"; // Default file name
dlg.DefaultExt = ".txt"; // Default file extension
dlg.Filter = "Text documents (.txt)|*.txt"; // Filter files by extension
// Show save file dialog box
Nullable<bool> result = dlg.ShowDialog();
buttonStart.IsEnabled = false;
buttonPause.IsEnabled = true;
buttonResume.IsEnabled = false;
fileCheck = true;
//Create drawing group
this.drawingGroup = new DrawingGroup();
this.leftLegDrawingGroup = new DrawingGroup();
this.rightLegDrawingGroup = new DrawingGroup();
//Create image source for WPF control
this.imageSource = new DrawingImage(this.drawingGroup);
this.leftLegBoxImageSource = new DrawingImage(this.leftLegDrawingGroup);
this.rightLegBoxImageSource = new DrawingImage(this.rightLegDrawingGroup);
leftLegColorBitmap = new WriteableBitmap(483, 152, 96, 96, PixelFormats.Bgr32, null);
rightLegColorBitmap = new WriteableBitmap(483, 152, 96, 96, PixelFormats.Bgr32, null);
colorBitmap = new WriteableBitmap(640, 480, 96, 96, PixelFormats.Bgr32, null);
colorPixels = new byte[this.sensor.ColorStream.FramePixelDataLength];
//Start Kinect- If no sensor, ask to connect one and exit.
try{
this.sensor.Start();
}
catch (IOException){
this.sensor = null;
//display error message here
MessageBox.Show("No Kinect sensor found. Please connect one and restart the application", "*****ERROR*****");
}
sensor.ElevationAngle = 0;
tracker = new Tracker(sensor, this, dlg.FileName);
}
當你幫助某人編碼問題時，你不要讓他們向你展示他們的代碼嗎？當然我們需要看代碼!!!! （只發布社區需要什麼幫助你，而不是整個項目） – Steven
