More than one year ago I started adding Kinect support to ARToolKit using libfreenect. I had some results but didn’t have enough time to publish a fully tested version of it. Now I know it ins’t very useful because Ubuntu already detects Kinect as a webcam (creating a /dev/videoX device for it, or at least that happend to me with Ubuntu 12.04 UPDATE: I figured out that this happens because of the gspca_kinect module introduced in Linux 3.0 kernel), so you can use it with ARToolKit via the GStreamer video input. Still I wanted to learn more on how ARToolKit works on its inside. Now I’ve added some more features and support not only for the RGB camera but also for the IR camera, tilt and LED.
The nature of the IR camera makes detecting markers very difficult as they are very blurry when not very close to the Kinect, but hey it’s been fun hacking with libfreenect. I’ll try to publish the code ASAP. I still want to test it more.
