to be able to eject them as bad parts at the end of the machine. Following various unsuccessful attempts with other technologies, the machine vision team from Harro Höfliger were able to solve this processing task with a frame grabber in combination with the Visual Applets software environment from Silicon Software. A computationally intensive part of the image processing is done by a field- programmable gate array (FPGA) on the frame grabber, thus reducing the Industrial PC’s CPU load through suitable image pre processing.
EXPERT PARTNERS “At this point in the process, which is crucial for the processing as a whole, it can be seen how important it is to co- operate with expert partners,” Sauer emphasises. “Following training by Silicon Software on the optimum use of the FPGA architecture on the frame grabber in combination with Visual Applets, we commissioned Stemmer Imaging to carry out the adjustments that were necessary for our special requirements. Stemmer Imaging took care of the FPGA programming and has continually developed the image processing system together with us so that, amongst other things, monochrome and colour

line scan cameras can be used.” Harro Höfliger has relied for many years
on its machine vision technology supplier. “Stemmer Imaging supports our open concept of selecting the optimum imaging components for each of our customers’ systems in order to be able to meet their individual requirements. The enormous variety of technologies and components for all disciplines of machine vision ensures that we can satisfy our customers’ wishes,” says Sauer. He also highlights the quick and reliable
advice that he and his team get from Stemmer Imaging: “It saves me time and effort if I can clarify all pending questions
or discuss new machine vision technologies with just one expert partner.” Harro Höfliger has now sold more than 100 of the systems described here worldwide. For future systems too, with web widths exceeding 300mm, Sauer is certain that, when it comes to machine vision, Stemmer Imaging will continue to be used as a component and technology partner for joint developments in the machine vision sector.
