ArUco marker-based displacement measurement technique: uncertainty analysis
Tommaso Tocci, Lorenzo Capponi, Gianluca Rossi
Abstract
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. With this method, an industrial camera can be used to measure the displacement of a structure through the detection of an ArUco marker. A comparison with an established reference technique has been carried out. The uncertainty due to repeatability measurement and the relevance of the acquisition and environmental parameters on the measurement results were researched.
