仅感应 kinect Xbox 360 前面特定区域的那些？

Question

我必须创建一个交互式菜单板。我正在使用 Kinect for Windows SDK v1.8。到目前为止，通过使用其内置的示例项目（控制基础 - Wpf）我能够导航（控制 kinecttile 按钮）。当我开始运行程序并且房间里没有人时，它可以完美运行，但是如果 kinect 传感器前面有多个人，则手（Kinect 鼠标指针）会在这里和那里移动。 现在我的问题
是否有任何选项 kinect 传感器仅检测特定区域中的人（例如 x=100-150,y=100-150,z=100-150）？ p>

这是处理骨架数据的代码。

 private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs skeletonFrameReadyEventArgs)
    {
        // Even though we un-register all our event handlers when the sensor
        // changes, there may still be an event for the old sensor in the queue
        // due to the way the KinectSensor delivers events.  So check again here.
        if (this.KinectSensor != sender)
        {
            return;
        }

        using (SkeletonFrame skeletonFrame = skeletonFrameReadyEventArgs.OpenSkeletonFrame())
        {
            if (null != skeletonFrame)
            {
                try
                {
                    // Copy the skeleton data from the frame to an array used for temporary storage
                    skeletonFrame.CopySkeletonDataTo(this.skeletons);

                    var accelerometerReading = this.KinectSensor.AccelerometerGetCurrentReading();

                    // Hand data to Interaction framework to be processed
                    this.interactionStream.ProcessSkeleton(this.skeletons, accelerometerReading, skeletonFrame.Timestamp);
                }
                catch (InvalidOperationException)
                {
                    // SkeletonFrame functions may throw when the sensor gets
                    // into a bad state.  Ignore the frame in that case.
                }
            }
        }
    }

我遇到了同样的问题通过使用下面的代码，我只跟踪了一个更靠近传感器的骨架。并直接将最近的骨架分配给主骨架流。

 private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs skeletonFrameReadyEventArgs)
    {
        Skeleton[] skeletons = new Skeleton[0];

        using (SkeletonFrame skeletonFrame = skeletonFrameReadyEventArgs.OpenSkeletonFrame())
        {
            if (skeletonFrame != null && this.skeletons != null)
            {
               //Console.WriteLine(skeletonFrame.SkeletonArrayLength);
                skeletons = new Skeleton[skeletonFrame.SkeletonArrayLength];

                // Set skeleton datas from skeletonFrame
                skeletonFrame.CopySkeletonDataTo(this.skeletons);

                TrackClosestSkeleton();
                Skeleton[] singleSkeleton = new Skeleton[6];

                Skeleton skl=(from mno in this.skeletons where mno.TrackingState==SkeletonTrackingState.Tracked && mno.TrackingId==globalClosestID select mno).FirstOrDefault();
                if (skl == null)
                    return;

                //Creating an empty skkeleton
                Skeleton emptySkeleton = new Skeleton();

                singleSkeleton[0] = skl;        //Pass the Tracked skeleton with closestID
                singleSkeleton[1] = emptySkeleton;  //Passing Empty Skeleton
                singleSkeleton[2] = emptySkeleton;  //Passing Empty Skeleton
                singleSkeleton[3] = emptySkeleton;  //Passing Empty Skeleton
                singleSkeleton[4] = emptySkeleton;  //Passing Empty Skeleton
                singleSkeleton[5] = emptySkeleton;  //Passing Empty Skeleton

                this.snew.SkeletonStream.ChooseSkeletons(globalClosestID);
                var accelerometerReading = this.KinectSensor.AccelerometerGetCurrentReading();
                this.interactionStream.ProcessSkeleton(singleSkeleton, accelerometerReading, skeletonFrame.Timestamp);

            }
        }
    }

int globalClosestID = 0;
    private void TrackClosestSkeleton()
    {
        if (this.snew != null && this.snew.SkeletonStream != null)
        {
            if (!this.snew.SkeletonStream.AppChoosesSkeletons)
            {
                this.snew.SkeletonStream.AppChoosesSkeletons = true; // Ensure AppChoosesSkeletons is set
            }

            float closestDistance = 10000f; // Start with a far enough distance
            int closestID = 0;

            foreach (Skeleton skeleton in this.skeletons.Where(s => s.TrackingState != SkeletonTrackingState.NotTracked))
            {
                if (skeleton.Position.Z < closestDistance)
                {
                    closestID = skeleton.TrackingId;
                    closestDistance = skeleton.Position.Z;
                }
            }

            if (closestID > 0)
            {
                this.snew.SkeletonStream.ChooseSkeletons(closestID); // Track this skeleton
                globalClosestID = closestID;
            }
        }
    }

检查上面的代码它对我有用。它可能对你有帮助。这里是 Kinectsensor。

最简单的解决方案是跟踪最近的骨架。

private void TrackClosestSkeleton()
  {
    if (this.kinect != null && this.kinect.SkeletonStream != null)
        {
        if (!this.kinect.SkeletonStream.AppChoosesSkeletons)
        {
        this.kinect.SkeletonStream.AppChoosesSkeletons = true; // Ensure AppChoosesSkeletons is set
        }

        float closestDistance = 10000f; // Start with a far enough distance
        int closestID = 0;

        foreach (Skeleton skeleton in this.skeletonData.Where(s => s.TrackingState != SkeletonTrackingState.NotTracked))
        {
        if (skeleton.Position.Z < closestDistance)
        {
          closestID = skeleton.TrackingId;
          closestDistance = skeleton.Position.Z;
        }
      }

      if (closestID > 0)
      {
        this.kinect.SkeletonStream.ChooseSkeletons(closestID); // Track this skeleton
      }
    }
  }

获取参考here

像这样使用它：

private void SensorSkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs skeletonFrameReadyEventArgs)
    {
        // Even though we un-register all our event handlers when the sensor
        // changes, there may still be an event for the old sensor in the queue
        // due to the way the KinectSensor delivers events.  So check again here.
        if (this.KinectSensor != sender)
        {
            return;
        }

        using (SkeletonFrame skeletonFrame = skeletonFrameReadyEventArgs.OpenSkeletonFrame())
        {
            if (null != skeletonFrame)
            {
                try
                {
                    // Copy the skeleton data from the frame to an array used for temporary storage
                    skeletonFrame.CopySkeletonDataTo(this.skeletons);
                    TrackClosesSkeleton();
                    var accelerometerReading = this.KinectSensor.AccelerometerGetCurrentReading();

                    // Hand data to Interaction framework to be processed
                    this.interactionStream.ProcessSkeleton(this.skeletons, accelerometerReading, skeletonFrame.Timestamp);
                }
                catch (InvalidOperationException)
                {
                    // SkeletonFrame functions may throw when the sensor gets
                    // into a bad state.  Ignore the frame in that case.
                }
            }
        }
    }

这只是一个快速编辑，所以也许您可以重命名一些变量以使其适合
