Beschreibung
Zusammenfassung:	A method of obtaining 3D geometric data of a body part comprises providing an elastic item 32, wherein least a portion of the elastic item comprises a pattern visible on the outer surface thereof, wherein the pattern has a predictable deformation on elongation. The method comprises applying the elastic item 32 about a body part 34 such that the elastic item 32 is elongated in at least one dimension and acquiring images of the elastic item when applied to the body part 36, wherein the images are acquired from a plurality of different orientations and/or positions. The method comprise processing said images to obtain 3D geometric data relating to the shape of the body part 38. An elastic sleeve 10 for obtaining 3D geometric data of a body part is provided. At least a portion of the elastic sleeve 10 comprises a pattern visible 12 on the outer surface thereof. On elongation in at least two dimensions, the pattern 12 deforms in a predictable and known manner.
