视频数据：骨骼数据采集（Skeleton Data）

骨骼数据不像前两个数据，转成字节数组，加载到图片控件上。

一个Kinect for windows设备最多识别6我的，其中只有两我的能识别完整，一个完整的人Kinect for windows中提供了全身20个关节的点，分别为：一、头（Head），二、肩中央（ShoulderCenter），三、左肩（ShoulderLeft），四、右肩（ShoulderRight），五、左肘（ElbowLeft），六、右肘（ElbowRight），七、左腕（WristLeft），八、右腕（WristRight），九、左手（HandLeft），十、右手（HandRight），十一、脊柱（Spine），十二、 髋中央（HipCenter），1三、左髋（HipLeft），1四、右髋（HipRight），1五、左膝（KneeLeft），1六、右膝（KneeRight），1七、左髁（AnkleLeft），1八、右髁（AnkleRight），1九、左脚（FootLeft），20、右脚（FootRight）。

本例能够从骨骼数据中获取这6我的的点，再找到被完整跟踪的人（最多两我的）的20个关节点显示在屏幕上。

新建一个 Winform项目。

而后写以下代码：

KinectSensor kinectsensor = null;
private void Form1_Shown(object sender, EventArgs e)
{
    //从Kinect集合中找到链接上的Kinect
    foreach (KinectSensor ks in KinectSensor.KinectSensors)
    {
        //找到链接的Kinect
        if (ks.Status == KinectStatus.Connected)
        {
            kinectsensor = ks;
            //平滑参数
            TransformSmoothParameters smoothingParam = new TransformSmoothParameters();
            //调用骨骼流
            kinectsensor.SkeletonStream.Enable(smoothingParam);
            //设置更近模
            kinectsensor.DepthStream.Range = DepthRange.Near;
            //骨骼模式为更近模式
            kinectsensor.SkeletonStream.EnableTrackingInNearRange = true;
            //坐姿或站姿  坐姿中识别上半身的10个点，默认模式识别全身20个点
            //kinectsensor.SkeletonStream.TrackingMode = SkeletonTrackingMode.Seated;
            //订阅骨骼识别事件
            kinectsensor.SkeletonFrameReady += kinectsensor_SkeletonFrameReady;
            kinectsensor.Start();//开始工做，便可以采集摄像头和红外摄像头信息
            this.Text = "Kinect开始工做……";
            return;
        }
    }
}
//定义骨骼数组,由于一个Kinect最多可识别6我的，其中两我的的骨骼的20个点能够识别，另4我的只识别成4个点
Skeleton[] skeletonDataArr;
void kinectsensor_SkeletonFrameReady(object sender, SkeletonFrameReadyEventArgs e)
{
    this.Refresh();

    using (SkeletonFrame skeletonFrame = e.OpenSkeletonFrame()) // Open the Skeleton frame
    {
        //实例化骨骼数组
