Abstract:
1. A system for formulating a three-dimensional data model of a shape of an amputee's stump in either a covered or uncovered condition, comprising: a structure generally in a shape of a ring, said ring of sufficient diameter to fit over and be spaced apart from the amputee's stump; four cameras secured to and in spaced arrangement about said structure, said cameras having lenses aimed at said stump; four light projectors secured to and in spaced arrangement about said structure, and in alternating arrangement with respect to said cameras, said projectors adapted to project light planes onto said stump; an actuator for initiating said cameras in a predetermined sequence to capture images of said light planes on said stump as at least one of said projectors project light planes onto said stump; a data storage device for storing data captured by said cameras; software for extracting two-dimensional edges of said captured light plane images from said stored data; and a data processor for processing said data so as to convert said two-dimensional edges to three-dimensional edges and to create therefrom a data model of the three-dimensional shape of said stump.
