ArUco marker-based displacement measurement technique: uncertainty analysis [PDF]
Engineering Research Express, 2021 Abstract The displacement response of structures can provide important information regarding their behaviours. Since image-based measurements have been considerably improved in recent years, in this research, a fiducial marker-based approach is exploited and a displacement measurement technique is proposed.
