視頻數據：深度數據採集（Depth Data）

深度數據是利用紅外發射攝像頭髮射紅外線，用紅外接收攝像頭接收紅外線而造成的圖像，在利用發射接收差來計算深度距離，從抓取的圖像中咱們能夠看出，紅外圖像是有遠近梯度的。

新建一個WPF項目，在窗體中添加一個Image控件，Name爲img。

後臺代碼以下：

//Kinect對象
KinectSensor kinectsensor = null;
private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
{
    if (kinectsensor.Status == KinectStatus.Connected)
    {
        kinectsensor.Stop();//中止Kinect
    }
}
private void Window_Loaded(object sender, RoutedEventArgs e)
{
    foreach (KinectSensor ks in KinectSensor.KinectSensors)
    {
        if (ks.Status == KinectStatus.Connected)
        {
            kinectsensor = ks;
            //設置深度數據流採集參數
            kinectsensor.DepthStream.Enable(DepthImageFormat.Resolution640x480Fps30);
            //訂閱深度數據流採集事件
            kinectsensor.DepthFrameReady += kinectsensor_DepthFrameReady;
            kinectsensor.Start();//啓動Kinect
            this.Title = "Kinect開始工做……";
            return;
        }
    }
}
private DepthImagePixel[] depthPixels;//定義字節數組
private WriteableBitmap DepthBitmap;//定義位圖
void kinectsensor_DepthFrameReady(object sender, DepthImageFrameReadyEventArgs e)
{
    using (DepthImageFrame depframe = e.OpenDepthImageFrame())
    {
        if (depframe != null)
        {
            //初始化字節數組
            depthPixels = new DepthImagePixel[kinectsensor.DepthStream.FramePixelDataLength];
            //把深度數據複製到數組中
            depframe.CopyDepthImagePixelDataTo(depthPixels);
            //實例化位圖對象
            this.DepthBitmap = new WriteableBitmap(kinectsensor.DepthStream.FrameWidth, kinectsensor.DepthStream.FrameHeight, 96.0, 96.0, PixelFormats.Bgr32, null);
            //用字節數組數據繪位圖
            this.DepthBitmap.WritePixels(new Int32Rect(0, 0, DepthBitmap.PixelWidth, DepthBitmap.PixelHeight), depthPixels, DepthBitmap.PixelWidth * sizeof(int), 0);
            //顯示位圖到圖片控件上
            img.Source = DepthBitmap;
        }
    }
}

效果以下圖：
