No - normally you can take a set of points that are lying on the floor say -
and tell the tracker that these all live on one plane, this then enables the
tracker to resolve based on this information.
Plus makes it easier t understand the point cloud.
Aligning the camera is, if I understand you correctly, a way of getting the
floor to be back on the floor plane of the scene, so the world is a sensible
way up.
Its a useful tool, odd that hasn't been requested before.
