    • A sensing apparatus comprising a sensing arrangement with a sensing end (32) for coming into contact with a surface of a body (26) to be scanned, a camera (30) and a connection apparatus (34) for the rigid connection of the camera to the sensing end, wherein the camera is arranged such that it can detect a surface (12) which has been provided with marks, which can be evaluated in an automatic and photogrammetric manner, and on which the body to be scanned has been placed, when the sensing end comes into contact with different points on the surface of the body to be scanned. The sensing apparatus further comprises a photogrammetric evaluation program for a computer unit (18), wherein the computer unit is configured such that image signals produced by the camera can be transmitted to the computer unit and the evaluation program can calculate the 3D coordinates of the surface to be scanned from the series of recorded and transmitted image sections using the marks (22), which can be evaluated in an automatic and photogrammetric manner. A method for detecting a three-dimensional physical shape of a body, in particular the physical shape of an interior of a hollow body, comprising the following steps: mounting the body to be digitalized on a surface (12) which is provided with marks (22), which can be evaluated in an automatic and photogrammetric manner, at known positions and providing the sensing apparatus. Further steps are the scanning of a point on the physical shape to be detected using the sensing end (32) of the sensing arrangement (28), recording at least one section of the photogrammetrically marked surface by way of the camera (30) while the sensing end scans the point, wherein a plurality of marks, which can be evaluated in a photogrammetric manner, is detected, and repeating the steps scanning and recording for a large number of different points of the physical shape to be detected. The recorded images are evaluated by an evaluation program.

    • The invention relates to a cost-efficient method and an arrangement for the 3D digitization of bodies and body parts, which creates dense and exact spatial coordinates despite imprecise optics and mechanics. The body to be digitized is placed onto a photogrammetrically marked surface, a photogrammetrically marked strap is applied to the body or body part to be digitized, and a triangulation arrangement comprising a camera and light pattern projector is moved on a path around the body. Through the photogrammetric evaluation of the photogrammetric marks of the surface and the strip located in the image field of the camera and the light traces of the light projector on the marked surface and the marked strip, all unknown inner and outer parameters of the triangulation arrangement are determined, and from the light traces on the unmarked body the absolute spatial coordinates of the body or the body part are determined with high pixel density and high accuracy, without separate calibration methods.
