Fig. 3. Camera positions and orientations obtained from the initial calibration and from the recalibration (view from above).

Fig. 4. (a) 3D positions of points corresponding to subset centres, in the reference state, the deformed state from the recalibrated images, and the deformed state if the previous parameters had kept being used after repositioning; (b) Displacement magnitude computed from the images from the recalibrated rig; (c) Error between the world coordinates of the deformed state obtained through the original setup and the repositioned setup.
