LCSR Seminar: Tim Bretl “What use are fiducial markers in Structure-from-Motion (SfM)?”
Everybody knows that adding fiducial markers to a scene will improve the performance of Structure-from-Motion (SfM) algorithms for vision-based 3D reconstruction, but nobody knows exactly how. I’ll show you several obvious ways to use markers that work poorly. Then, I’ll show you a simple but less obvious way to use them that seems to work very well.
