Abstract

In the field of custom foot orthosis bio-mechanics specialists take negative casts of the patient's feet and produce a positive on which they apply corrective elements. The corrected positive cast is then used to thermoform an orthosis. Several production steps can be simplified or eliminated by a 3D-acquisition of the underside of the foot. Such a complete custom footwear system, developed by Neogenix Technologies Inc., has been reported last year in IS and T/SPIE's symposium. A major improvement aimed at maximizing the coverage of the underside of foot surface has been achieved since by using multiple structured light projection technique. A description of a patent pending hardware set-up and range data extraction by software will be given in this paper.
