TECHNOLOGY Machine vision Seeing things


We all hear about how machine vision is so vital for ITS applications, but what exactly is it, what is it used for and what are the challenges and opportunities? And most importantly, so we can work out how to use it for new applications, what is the future of the technology?


“N


ow we’re up to using five megapixel cameras I can see an 18 foot or 6m field of view which is very important.,” says Jim Kennedy, the CEO


of INEX/ZAMIR. “Here before we had to use multiple ana- logue cameras to get the same coverage and that became both real estate expensive and equipment expensive.” Jim is certain that the move to digital technology changed


his industry and allowed far more to be done with pictures. Eddy Vermeulen, Product Manager at FLIR ITS, formerly


Traficon, agrees that it was a game-changer: “We used to have all analogue cameras with a standard


PAL or NTSC output on a rather standard low resolution. You see now more and more people moving into the IP world where video is being streamed to different locations over a complicated network, even towards remote locations.” In fact, some businesses only came into the market when


digital technology broke through, for example Basler, which concentrates on making the cameras used for a variety of purposes, as product line manager Enzio Schneider explains. “In the beginning we started with digital cameras because


we did not get the cameras on the market we needed for our solutions, back in the 1990s. Then we started developing our own cameras and this showed up to be a very good business and this is why we are focussing on this business which is not as cyclic as many other single markets in the world.” Basler concentrates on making the cameras to be used by


other companies for their specific needs. “Previously we were a full provider of full solutions for


specific markets but this changed over the last year so right now we are only a camera supplier so we focus on the cam- era itself,. providing the eye to the systems. We have a broad portfolio of different cameras like line scan cameras, area scan cameras, IP cameras for some applications and we are able to cover a vast range of different applications with this broad portfolio.” But, as FLIR ITS’s Vermeulen explains, there has been a significant amount of adapting required:

“You have so many possible combinations that it becomes more complicated to match two or three or more systems to the other. It requires a different kind of knowledge”
