Not just the camera and its housing have been developed by the DLR researchers in Göttingen – so too has the measurement technology employed. This involves using two cameras with different angles of view (stereoscopy) to take images of the object under investigation. A computer identifies the equivalent points in the images – the dot pattern helps with this. Knowing the position and attitude of the cameras enables the entire surface being observed to be represented in 3D.
