Part 2: Cognex LCD Vehicle Display Tester

Welcome back to the blog! Today, I will be talking about how to operate a Cognex smart camera via a LabVIEW program. The way I will be communicating with the camera is via TCP/IP. There are other potential ways to communicate with the camera from LabVIEW, but this was determined to be the best way, giving us the most control over the camera. I will walk through some basic terminology that is necessary to discuss building a Cognex vision test. Then, I will create and set up a vision test and finally, I will briefly describe how to program LabVIEW to send/receive information to the camera and to trigger an image acquisition.

Part 1: Cognex LCD Vehicle Display Tester


As LCD vehicle displays have become more prevalent and versatile in both on- and off-highway, the time it takes to ensure proper display functionality after a software release has increased dramatically. It is not uncommon for displays to have 15, 20, or even 30 different screens, each of which having multiple sub-selections available. If you take into consideration different supported languages, the scope of the test grows dramatically. DISTek, as a company, is always attempting to define the future needs of customers in the off-highway industry, of which vehicle display testers are one of those needs.
