CollectFaceDataAsync不会调用委托 [英] CollectFaceDataAsync doesn't invoke delegates

问题描述

在Unity Pro插件FaceModelBuilder没有BeginFaceDataCollection（）或GetFaceData（）或CollectionCompleted事件。

所以ColectFaceDataAsync是唯一的选择。

我的代码如下：

 public void StartCapture（）
 {
 this.StopFaceCapture（）; 
 
 this.faceModelBuilder = null; 
 
 this.faceModelBuilder = this.highDefinitionFaceFrameSource.OpenModelBuilder（FaceModelBuilderAttributes.None）; 
 
 this.faceModelBuilder.CollectFaceDataAsync（（动作< Microsoft.Kinect.Face.FaceModelData>）CollectionSuccess，（动作< INT>）CollectionFailure）; // BeginFaceDataCollection（）; 
} 

 void CollectionSuccess（FaceModelData modelData）
 {
 this.currentFaceModel = modelData.ProduceFaceModel（）; 
 
 this.faceModelBuilder.Dispose（）; 
 this.faceModelBuilder = null; 
 
 this.CurrentBuilderStatus =" Capture Complete" ;; 
 this.UpdateMesh（）; 
} 

但从不调用CollectionSuccess（），即使CheckOnBuilderStatus（）给出"完整"

解决方案

永远不会立即调用它，因为它需要不同的面部视图。如果您查看WPF示例，您将看到需要获得左/右/上/下视图才能成功。

您可能希望在更新循环中添加一个检查看的状态是什么：

<预类= "prettyprint">如果（！faceModelBulder = NULL）
{
变种captureStatus = faceModelBuilder.CaptureStatus;

//向用户提供一些反馈。
}

FaceModelBuilder in Unity Pro plugin doesn't have BeginFaceDataCollection() or GetFaceData() or CollectionCompleted event.

so ColectFaceDataAsync is the only option.

my code is like :

public void StartCapture()
	{
		this.StopFaceCapture();
		
		this.faceModelBuilder = null;
		
		this.faceModelBuilder = this.highDefinitionFaceFrameSource.OpenModelBuilder(FaceModelBuilderAttributes.None);
		
		this.faceModelBuilder.CollectFaceDataAsync ((Action<Microsoft.Kinect.Face.FaceModelData>)CollectionSuccess, (Action<int>)CollectionFailure);	   //BeginFaceDataCollection();
	}

void CollectionSuccess(FaceModelData modelData)
	{		
		this.currentFaceModel = modelData.ProduceFaceModel();
		
		this.faceModelBuilder.Dispose();
		this.faceModelBuilder = null;
		
		this.CurrentBuilderStatus = "Capture Complete";
		this.UpdateMesh();
	}

but CollectionSuccess() is never called, even CheckOnBuilderStatus() gives a "Complete"

解决方案

It will never be called immediately as it needs different views of the face. If you review the WPF sample, you will see that you need to get left/right/up/down views until it can succeed.

You may want to put in your update loop a check to see what the state is:

if(faceModelBulder != null)
{
   var captureStatus = faceModelBuilder.CaptureStatus;
   
   // provide some feedback to user.
}
