Abstract

This paper outlines the specifications for a machine vision COD (MVCOD) gauge and describes some of the steps in designing such a MVCOD system. In particular, we discuss how to select illumination equipment and cameras, calibration techniques, image processing algorithms, and methods for integrating the MVCOD equipment into the complete computer-controlled materials testing system. In addition, we present test data to show the effects of component selections on the final system performance.
