Abstract

In this paper we discuss how to design a practical height gauging system based on the structured lighting approaches described. We show how some of the system limitations caused by the illumination and observation geometry affect component specifications. Examples of a machine vision inspection applications designed using these design principles is presented and analyzed. Finally, we discuss methods to extend this method.
