The issue might be that you are capturing tie points that are all in the same plane. The resulting linear equation system will be either under-determined or very ill-conditioned. During the first 12 tie points you collect, aim to get some that are as low as possible, and some that are above where you anticipate your sand surface is going to be when it’s piled up.

Having different projector and camera positions should not be a problem. But when capturing tie points, ensure that the calibration disk is facing the kinect, not the projector.
