2. Kinect Getting Started Camera Control http://www. codeproject
Camera control: you can control the camera angle programmatically
namespace Microsoft.Research.Kinect.Nui {
public class Camera
public static readonly int ElevationMaximum;
public static readonly int ElevationMinimum;
public int ElevationAngle { get; set; }
public string UniqueDeviceName { get; }
public void GetColorPixelCoordinatesFromDepthPixel
(ImageResolution colorResolution, ImageViewArea viewArea,
int depthX, int depthY, short depthValue, out int colorX,
out int colorY); }

Create a new WPF project named KinectCameraControl
UI design
TextBlock

txtCameraName
Button
btnStart
btnStop
btnCameraUp
btnCameraDown
BtnStartClick
BtnStopClick
BtnCameraUpClick
BtnCameraDownClick

4. Kinect Getting Started Camera Control http://www. codeproject
Add reference to Microsoft.Research.Kinect library
Add using Microsoft.Research.Kinect.Nui include
Add member variable:
Runtime kinectNui;
private Camera cam;
int totalFrames = 0;
int lastFrames = 0;
DateTime lastTime = DateTime.MaxValue;

5. Kinect Getting Started Camera Control http://www. codeproject
Add InitializeNui() method
private void InitializeNui() {
try {
kinectNui = new Runtime();
kinectNui.Initialize(RuntimeOptions.UseColor);
kinectNui.VideoStream.Open(ImageStreamType.Video, 2,
ImageResolution.Resolution640x480, ImageType.ColorYuv);
lastTime = DateTime.Now;
cam = kinectNui.NuiCamera;
txtCameraName.Text = cam.UniqueDeviceName;
kinectNui.VideoFrameReady += new EventHandler<ImageFrameReadyEventArgs>(NuiVideoFrameReady); }
catch (InvalidOperationException ex) {
MessageBox.Show(ex.Message);

6. Kinect Getting Started Camera Control http://www. codeproject
Add NuiVideoFrameReady() event handler method
void NuiVideoFrameReady(object sender, ImageFrameReadyEventArgs e) {
PlanarImage Image = e.ImageFrame.Image;
image.Source = BitmapSource.Create(
Image.Width, Image.Height, 96, 96, PixelFormats.Bgr32, null,
Image.Bits, Image.Width * Image.BytesPerPixel);
CalculateFps(); }
void CalculateFps() {
++totalFrames;
var cur = DateTime.Now;
if (cur.Subtract(lastTime) > TimeSpan.FromSeconds(1))
int frameDiff = totalFrames - lastFrames;
lastFrames = totalFrames;
lastTime = cur;
frameRate.Text = frameDiff.ToString() + " fps";
txtElevationAngle.Content = cam.ElevationAngle.ToString();

7. Kinect Getting Started Camera Control http://www. codeproject
Add BtnCameraUpClick() event handler method
private void BtnCameraUpClick(object sender, RoutedEventArgs e) {
try
cam.ElevationAngle = cam.ElevationAngle + 5; }
catch (InvalidOperationException ex)
MessageBox.Show(ex.Message);
catch (ArgumentOutOfRangeException outOfRangeException)
//Elevation angle must be between Elevation Minimum/Maximum"
MessageBox.Show(outOfRangeException.Message);

8. Kinect Getting Started Camera Control http://www. codeproject
Add BtnCameraDownClick() event handler method
private void BtnCameraDownClick(object sender, RoutedEventArgs e) {
try
cam.ElevationAngle = cam.ElevationAngle - 5; }
catch (InvalidOperationException ex)
MessageBox.Show(ex.Message);
catch (ArgumentOutOfRangeException outOfRangeException)
//Elevation angle must be between Elevation Minimum/Maximum"
MessageBox.Show(outOfRangeException.Message);

9. Kinect Getting Started Camera Control http://www. codeproject
Add BtnStartClick() and BtnStopClick event handler methods
private void BtnStartClick(object sender, RoutedEventArgs e) {
InitializeNui();
btnStop.IsEnabled = true;
btnStart.IsEnabled = false; }
private void BtnStopClick(object sender, RoutedEventArgs e)
kinectNui.Uninitialize();
btnStop.IsEnabled = false;
btnStart.IsEnabled = true;
private void WindowClosed(object sender, EventArgs e)
