Abstract
For largely automated production of artificial limbs or adapted moldings, digitized three-dimensional image data of the shape of body or body parts are obtained, particularly of human body parts or limbs. The body or body part is covered by a thin, tight-fitting, preferably elastic envelope carrying a high-contrast pattern that is imaged by several cameras cooperating in the manner of stereo cameras having overlapping image areas. The image signals furnished by the cameras are digitized and supplied to a computer that computes the digitized data of the three-dimensional shape by automatic coordination of corresponding patterns in each of the recorded images.

A method for digitized three-dimensional sensing of the shape of bodies or body parts, particularly human body parts or limbs, for largely automated production of artificial limbs or adapted body parts, said method comprising the steps of:
- covering said body or body part with a thin, tight-fitting envelope carrying a high-contrast pattern;
- recovering images of the covered body or body part with a plurality of cameras cooperating in the manner of stereo cameras having overlapping image areas;
- and
- obtaining, by computerized automatic coordination of the corresponding high-contrast pattern recorded in each of the images taken by said cameras, digitized data representative of three-dimensional shape.
