A "motion map" ? I think you'd better read the paper again. They compute a full 3D reconstruction. Much much more computationally expensive. You would not "be able to create a similar motion map using the gyroscope data".

Oops, good point! I forgot that they calculated the geometry and stitched the images to create novel frames.

The gyroscope data most certainly would not allow one to do the same.
