ABSTRACT
Three-dimensional systems have grown in use as the capability to handle the information has improved. Specifically for reverse-engineering applications, the interfaces to computer-aided design systems have become a viable tool of the commercial systems. Higher speed and resolution through interferometric methods have supplemented the proven capabilities of well-established laser triangulation systems. Triangulation-based systems show the highest degree of use in the industry. The challenge for industrial contouring technologies is becoming less, one of new sensors, and more, one of how to use the extensive, fast data generated. Reverse engineering applied to models and prototype parts offers yet another tool to the design process. Ideas can be quickly turned into models, and then back into computer databases.
