Abstract

This paper describes a system which integrates computer vision and rapid manufacturing technologies to scan physical objects and to replicate the reconstructed shapes as steel faced dies using shaping deposition processes. A light-stripe range finder is used to scan the 3-D data of the object. Range data is then processed in order to generate a solid model representation. The computer model is then replicated as a plastic prototype with stereolithography Finally, this prototype is used as a pattern in a thermal spray process to build a metal-faced die replica of the original object. The system is demonstrated by scanning a human face which is then replicated as a stainless-steel sculpture.
