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.
