3D deformation mapping
Stereo Digital Image Correlation (DIC) techniques make it possible to measure 3D locations and deformations of surfaces using two camera’s. MARIN has already applied this technique for years to measure the deflection/location of propellers, floating solar panels, ship motions and even waves and wake fields of full-scale vessels. We typically explore the boundaries of the stereo vision techniques and use advanced cameras, lenses and calibration methods to get accurate results. The main advantage of DIC is that a surface can be measured from a distance, without the need of instrumenting the surface, as long as the surface itself has distinctive features which can be traced with the cameras.
