Machine Vision Is More Than on the Mark
Customer demands are driving vendors to push the boundaries of machine vision technology, leading to faster, smarter and higher-resolution systems.
by Hank Hogan, Contributing Editor
Northrop Grumman Corp., like any other defense contractor, needs to track parts throughout the production line and onward through subsequent use. That need is faced by automotive parts suppliers as well and is a nearly universal aspiration among all types of manufacturers. The solution mandated to contractors by the US Department of Defense is a two-dimensional matrix of dots that marks an item with a unique, specific and omnipresent identification code. That requirement, in turn, fuels a demand for specialized machine vision systems.
