Abstract: This paper presents a fiducial-based approach to monitoring the movement of breakwater armour units in a model hall environment. Target symbols with known dimensions are attached to the physical models, allowing the recovery of three-dimensional positional information using only a single camera. The before-change and after-change fiducial positions are matched optimally, allowing the recovery of three-dimensional movement vectors representing the shifts in the positions of the physical models. Experimental results show that sub-millimeter accuracies are possible using 6-megapixel images of an A4-scale scene.
