The Kinect camera’s 3D scanning quality declines rapidly at larger distances, which is why we recommend the standard 100cm x 75cm size. Aim your Kinect camera at a flat wall from about 2m away, and look at the 3D scan using the KinectViewer application. You will see a soup bowl instead of a flat plane. That is what throws off projector calibration.

You might be able to improve alignment by running a per-pixel depth calibration procedure on your Kinect, as described in the Kinect package’s README file. Under ideal circumstances, per-pixel calibration will turn the soup bowl back into something approximating a plane, which would then fix alignment.
