我刚刚获得了我全新的Kinect for Windows v2,我有一些来自我希望移植的旧SDK的程序,而且从msdn它应该很容易。从SDK附带的示例中,我觉得我对新功能有一些不错的理解,我得到了颜色,深度和身体(旧骨架)的工作。现在我只是不想让面部跟踪运行起来。这里开始我的问题。
如果我想要颜色数据:
_kinectSensor = KinectSensor.GetDefault();
_colorFrameReader = _kinectSensor.ColorFrameSource.OpenReader();
_colorFrameReader.FrameArrived += _colorFrameReader_FrameArrived;
_kinectSensor.Open();
如果我想要身体数据:
_bodyFrameReader = _kinectSensor.BodyFrameSource.OpenReader();
bodyFrameReader.FrameArrived += this.Reader_FrameArrived;
_kinectSensor.Open();
但如果我想获得面部数据,我永远不会得到回调:
var faceFrameSource = new FaceFrameSource(KinectSensor.GetDefault());
_faceFrameReader = faceFrameSource.OpenReader();
_faceFrameReader.FrameArrived +=_faceFrameReader_FrameArrived;
_kinectSensor.Open();
任何人都可以帮我了解如何在kinect v2 sdk中进行面部跟踪吗?
答案 0 :(得分:2)
我找到了一个基于@Marks评论的解决方案,这篇文章:http://www.kinectingforwindows.com/
我首先需要设置trackingId和faceframwfeatures,当我得到一个跟踪的身体时,我会这样做:
private void bodyFrameReader_FrameArrived(object sender, BodyFrameArrivedEventArgs e)
{
var dataReceived = false;
using (var bodyFrame = e.FrameReference.AcquireFrame())
{
if (bodyFrame != null)
{
if (_bodies == null)
{
_bodies = new Body[bodyFrame.BodyCount];
}
bodyFrame.GetAndRefreshBodyData(_bodies);
dataReceived = true;
}
}
if (dataReceived)
{
foreach (var body in _bodies)
{
if(!body.IsTracked)
continue;
if (_player == null)
PlayerFound(body);
}
}
}
PlayTracked将_player设置为正文,并启动面部跟踪:
private void PlayerFound(Body body)
{
_player = body;
StartFaceTracting(body);
}
然后开始跟踪:
private void StartFaceTracting(Body body)
{
// Face
_faceFrameSource = new FaceFrameSource(KinectSensor.GetDefault())
{
FaceFrameFeatures = FaceFrameFeatures.BoundingBoxInColorSpace | FaceFrameFeatures.PointsInColorSpace,
TrackingId = body.TrackingId
};
_faceFrameSource.TrackingIdLost += _faceFrameSource_TrackingIdLost;
_faceFrameReader = _faceFrameSource.OpenReader();
_faceFrameReader.FrameArrived += _faceFrameReader_FrameArrived;
Log.Info("Facetracking strated Id: " + body.TrackingId);
}
然后我需要最后一个非常重要的事情,即post build事件,即将NuiDatabase复制到我安装的输出文件夹中:“C:\ Program Files(x86)\ Microsoft SDKs \ Windows \ v8。 0 \ ExtensionSDKs \ Microsoft.Kinect.Face \ 2.0 \的Redist \ CommonConfiguration \ 64 \ NuiDatabase“:
在我运行post build事件之后,我在FaceFrame中获得了数据:)
