Abstract
In a cost-efficient method and arrangement for 3D digitization of bodies and body parts, which produces dense and exact spatial coordinates despite imprecise optics and mechanics, the body to be digitized is placed on a photogrammetrically marked surface, a photogrammetrically marked band is fitted to the body or body part to be digitized, and a triangulation arrangement comprised of a camera and a light pattern projector is moved on a path around the body. By a photogrammetric evaluation of the photogrammetric marks of the surface and the band situated in the image field of the camera, and of the light traces of the light projector on the marked surface and the marked band, all unknown internal and external parameters of the triangulation arrangement are determined, and the absolute spatial coordinates of the body or body part are established from the light traces on the non-marked body with high point density and high precision without any separate calibration methods.
