Abstract
The invention relates to a method of detecting the 3D shape of objects, in which the object is pressed into a plastically deformable mass provided with markers adapted to be evaluated photogrammetrically. After removal of the object from the marked mass, a plurality of photogrammetric images are taken from different views, and the images are evaluated photogrammetrically, the 3D shape of the object being calculated using an association of the markers corresponding in the images. The invention further relates to a corresponding arrangement for carrying out the method and is particularly suited for the detection of the 3D shape of objects whose 3D shape changes under load. One example of this would be the measurement of human feet.
