Running the Kinect RGBDemo Application

Running the Kinect RGBDemo Application

Ok if you have been following my recent posts you now have the Kinect RGBDemo up and running on your machine.  Lets give it a test run.

When you first launch the rgdb-viewer application you�ll see something like this:

The box in the upper right hand corner shows us a regular web cam image.  The main window is the image from the distance measuring camera.  Here we have an x-y grid where color at each point represents the distance from the camera.  (Here red stuff is closer than green stuff)

 

Now lets see how we can use this information to make some 3-d images.

 

Here is me in 3D view (not too great) the black parts are shadows were my body is in the way of the structured laser projector so it can�t tell what is behind me.  Now from since each pixel in this image also has distance information I can rotate the image like this:

 

 

Now this is the same image just rotated� see how the we can see that the Red Bull can was positioned relative to my head?  Pretty cool!  NOTE: if I had another Kinect capturing data from another angle OR I had someone to move my single Kinect around a bit we could fill in all of those shadow areas.

 

So that is just a bit of the RGBDemo.  Give it a shot it is a lot of fun to play with.  Next time we�ll begin to write some of our own software to capture Kinect data!
