Abstract
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.
Claims13
A method of optically detecting the three-dimensional shape of an interior space defined by an inner wall of a product adapted to fit the shape of a body part, comprising the steps of:
- providing said interior space with an elastic envelope in snug contact with the inner wall, said elastic envelope being provided with marks facing the inside of the space and adapted to be evaluated photogrammetrically;
- producing a number of overlapping image recordings of said interior space marked in this way with the aid of one or more 2D-cameras;
- and,
- photogrammetrically evaluating said recordings for determining the three-dimensional shape of that part of said interior space that was detected by said overlapping recordings.
