視頻數據：骨骼數據採集（Skeleton Data）

骨骼數據不像前兩個數據，轉成字節數組，加載到圖片控件上。

一個Kinect for windows設備最多識別6我的，其中只有兩我的能識別完整，一個完整的人Kinect for windows中提供了全身20個關節的點，分別爲：一、頭（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、 髖中央（HipCenter），1三、左髖（HipLeft），1四、右髖（HipRight），1五、左膝（KneeLeft），1六、右膝（KneeRight），1七、左髁（AnkleLeft），1八、右髁（AnkleRight），1九、左腳（FootLeft），20、右腳（FootRight）。

本例能夠從骨骼數據中獲取這6我的的點，再找到被完整跟蹤的人（最多兩我的）的20個關節點顯示在屏幕上。

新建一個 Winform項目。

而後寫以下代碼：

KinectSensor kinectsensor = null;
private void Form1_Shown(object sender, EventArgs e)
{
    //從Kinect集合中找到鏈接上的Kinect
    foreach (KinectSensor ks in KinectSensor.KinectSensors)
    {
        //找到鏈接的Kinect
        if (ks.Status == KinectStatus.Connected)
        {
            kinectsensor = ks;
            //平滑參數
            TransformSmoothParameters smoothingParam = new TransformSmoothParameters();
            //調用骨骼流
            kinectsensor.SkeletonStream.Enable(smoothingParam);
            //設置更近模
            kinectsensor.DepthStream.Range = DepthRange.Near;
            //骨骼模式爲更近模式
            kinectsensor.SkeletonStream.EnableTrackingInNearRange = true;
            //坐姿或站姿  坐姿中識別上半身的10個點，默認模式識別全身20個點
            //kinectsensor.SkeletonStream.TrackingMode = SkeletonTrackingMode.Seated;
            //訂閱骨骼識別事件
            kinectsensor.SkeletonFrameReady += kinectsensor_SkeletonFrameReady;
            kinectsensor.Start();//開始工做，便可以採集攝像頭和紅外攝像頭信息
            this.Text = "Kinect開始工做……";
            return;
        }
    }
}
