我从头开始编写了一个Kinect滑动测试程序，读取了由Visual gesture builder Kinect Swipe Test Project here.生成的gbd文件
我想在这个问题中关注的主要4个手势是左和右。右手举起，左手和右手右手向上滑动。
在上面发布的github链接中，它可以很好地集成在一起。
然而，当我将代码移植到我的主项目时，左手握手 向上和向右向上滑动手势均出现故障。两个姿态 无法被发现。
我无法在此发布我的主项目，因此我将发布我在2个主要项目文件上实施的代码片段，主要是GestureDetector.cs和GestureResultsView.cs
以下是我遇到文件问题的相应片段。
GestureDetector.cs：
public class GestureDetector : IDisposable
{
//stores an array of paths that leads to the gbd files
private string[] databaseArray = {//Left Hand
@"Database\LeftHandDownToTop.gbd"
//, @"Database\LeftHandHandsUp.gbd"
//, @"Database\LeftHandLeftToRight.gbd"
//, @"Database\LeftHandRightToLeft.gbd"
//Right Hand
, @"Database\RightHandBottomToUp.gbd"
, @"Database\RightHandHandsUp.gbd"
//, @"Database\RightHandLeftToRight.gbd"
//, @"Database\RightHandRightToLeft.gbd"
};
//stores an array of the names of the gesture found inside the gbd file
private string[] databaseGestureNameArray = { //Swipe Up
"SwipeUp_Left",
"SwipeUp_Right",
//Swipe Right
//"SwipeRight_Left",
//"SwipeRight_Right",
//Swipe Left
// "SwipeLeft_Left",
// "SwipeLeft_Right",
//Hands Up
//"HandsUp_Left",
"HandsUp_Right"
};
for (int i = 0; i < databaseArray.Length; i++)
{
// load the 'Seated' gesture from the gesture database
using (VisualGestureBuilderDatabase database = new VisualGestureBuilderDatabase(databaseArray[i]))
{
// we could load all available gestures in the database with a call to vgbFrameSource.AddGestures(database.AvailableGestures),
// but for this program, we only want to track one discrete gesture from the database, so we'll load it by name
foreach (Gesture gesture in database.AvailableGestures)
{
if (gesture.Name.Equals(databaseGestureNameArray[i]))
{
this.vgbFrameSource.AddGesture(gesture);
}
}
}
}
}

private void Reader_GestureFrameArrived(object sender, VisualGestureBuilderFrameArrivedEventArgs e)
{
VisualGestureBuilderFrameReference frameReference = e.FrameReference;
using (VisualGestureBuilderFrame frame = frameReference.AcquireFrame())
{
if (frame != null)
{
// get the discrete gesture results which arrived with the latest frame
IReadOnlyDictionary<Gesture, DiscreteGestureResult> discreteResults = frame.DiscreteGestureResults;
bool foundGesture = false;
if (discreteResults != null)
{
// we only have one gesture in this source object, but you can get multiple gestures
foreach (Gesture gesture in this.vgbFrameSource.Gestures)
{
for (int i = 0; i < databaseGestureNameArray.Length; i++)
{
if (gesture.Name.Equals(databaseGestureNameArray[i]) && gesture.GestureType == GestureType.Discrete)
{
DiscreteGestureResult result = null;
discreteResults.TryGetValue(gesture, out result);
if (result != null && !foundGesture)
{
// update the GestureResultView object with new gesture result values & update the label
foundGesture = this.GestureResultView.UpdateGestureResult(true, result.Detected, result.Confidence, databaseGestureNameArray[i]);
}
}
}
}
}
}
}
}
GestureResultView.cs：
public bool UpdateGestureResult(bool isBodyTrackingIdValid, bool isGestureDetected, float detectionConfidence, string gestureName)
{
this.IsTracked = isBodyTrackingIdValid;
this.Confidence = 0.0f;
bool gestureFound = false;
if (!this.IsTracked)
{
this.ImageSource = this.notTrackedImage;
this.Detected = false;
this.BodyColor = Brushes.Gray;
}
else
{
this.Detected = isGestureDetected;
this.BodyColor = this.trackedColors[this.BodyIndex];
if (this.Detected)
{
this.Confidence = detectionConfidence;
if (this.Confidence > 0.4)
{
this.ImageSource = this.seatedImage;
