ArUco marker-based displacement measurement technique: uncertainty analysis

The displacement response of structures can provide important information regarding their behaviours. Since image-based measurements have been considerably improved in recent years, this research, a fiducial marker-based approach is exploited and measurement technique proposed. With method, an industrial camera be used to measure the structure through detection ArUco marker. A comparison with established reference has carried out. uncertainty due repeatability relevance acquisition environmental parameters on results were researched.
