Reconstruction Accuracy Assessment of Surface and Underwater 3D Motion Analysis: A New Approach

Figure 5

(a) RMS errors for the 3D reconstruction of surface cameras without (dotted line) and with homography (continuous grey line) transformation obtained from subsets of 40/64 control points positioned on the horizontal and vertical corner rods. Trial subsets in the -axis represent the (arbitrary) ID of the simulation case with different subsets of control points. (b) RMS errors for the 3D reconstruction of underwater cameras without (dotted line) and with homography (continuous grey line) transformation obtained from subsets of 48/88 control points positioned on the horizontal and vertical corner rods. Trial subsets in the -axis represent the (arbitrary) ID of the simulation case with different subsets of control points.
