Will Changing Machine Vision Standards Cut Costs and Boost Performance?
Forthcoming revisions to Camera Link and GenICam might aid camera makers and users alike.
by Hank Hogan, Contributing Editor
Upcoming changes in the communications standards that drive machine vision could mean cheaper and more capable setups as well as a greater ability to mix and match hardware and software. Developments throughout the next year in the Camera Link and GenICam standards also could make things easier and less costly for manufacturers and end users alike. A look at these changes reveals what their impact might be.
Generalizing GenICam
With regard to GenICam, plans call for the standardized and unified programming interface for cameras to extend its reach in several directions. One such extension is to have the standard cover not just the camera but also the transport layer — or the driver and interface — that connects the camera to the controlling software. Another extension involves the syntax in the camera description, which is typically stored in an xml file within the camera itself. A third involves a protocol driver for Camera Link, which would enable devices using that system to be treated in the software as a GigE Vision or IEEE-1394 camera...
