Abstract

A method of detecting the 3D shape of an object by photogrammetry, in which a plurality of photogrammetric point markers and a plurality of connecting markers are provided on the surface of the object, each connecting marker connecting a subset of the plurality of point markers with each other, with at least two different types of point markers existing that differ from each other in their optical configuration, and some of the point markers provided along a connecting marker are formed in such a way that the sequence of their optical configurations results in a predetermined code that characterizes the respective connecting marker, a plurality of photogrammetric images of the object are taken from different views, an image processing of the images is performed, in which first the connecting markers mutually corresponding to each other in the images are associated with one another using their respective code, and then the point markers connected with each other by the respective connecting marker are associated with one another with the aid of the connecting marker association in the images, and using the point marker association, the 3D shape of the object is determined by means of a photogrammetric evaluation process. The invention further relates to an arrangement for carrying out the method.
