With the vision camera interfaced directly to an Ethernet POWERLINK network, systems are able to effectively manage both cyclical data for high-speed operation and asynchronous communications for increased application flexibility. Use of multi-channel TCP/IP communications simplifies non-real-time transfers. (Source: Cognex)
Al thanks for covering this topic and this particular advance. I'm not surprised Cognex is at the forefront; their engineers (and management) tend to think about systems and networks, not just cameras.
I have to hand it to Cognex, especially the marketing department as they really know how to brag about their products. I've used Cognex cameras with great success for image analysis and their software is first rate. Very easy to setup for pattern detection and other stuff.
That said, their barcode reading isn't that great, regardless what they ads might say. We had them come in and demo a system and it was going to take four of their expensive cameras to cover the field of view to read what we needed, and they still had some problems. I'd trust a more experienced barcode reading company for serious barcode reading. (I used to work for one, so I feel justified in saying this....)
And, I wish that they wouldn't email me so many stinkin' ads. I get more marketing emails from Cognex than any other controls related company!
a.saji, I used to cover machine vision for another publication, and noticed that Cognex was one of the few camera makes who seemed to consider more than just the camera and what it's immediately attached to. That said, I've also heard complaints like Jim_E's about their barcode readers.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
