A cost-effective method for detecting the three-dimensional shape of interior spaces such as footwear, prosthesis funnels, etc. is described. For this purpose the inner wall of the interior space is lined with a formfitting, elastic and photogrammetrically marked envelope ( 2 ), a series of overlapping recordings of said interior space marked in this way is produced with the aid of one or more imaging devices ( 4 ) and from this the 3D-shape of the interior space is determined using photogrammetrical methods. The invention describes various methods of lining the interior space, of guiding the imaging devices ( 9 ) into the different recording positions and of the type of the measurable interior spaces.
