Machine Vision & Imaging Systems
Today's production engineers are constantly striving to produce the highest volume of output with the minimum number of defects possible. Traditionally, end-of-line inspection would be carried out manually, but this can prove unreliable and expensive.
Modern PCs, coupled with specialist image processing software and hardware can often provide a cost effective alternative, capable of uninterrupted operation twenty-four hours a day, seven days a week.

Image Capture SystemsThere are many systems available to facilitate capturing video to PC, ranging in terms of cost, performance and ease of use. Consumer-grade & web-cam style devices can be controlled using tools such Windows Media Encoder, or the WyeTec Image Capture Control that can be downloaded from this website. Control of high-speed, large format or high dynamic range cameras requires more specialist tools - frame-grabbers with sophisticated interfaces, and software to control them. The WyeTec engineers have particular experience with the Matrox Imaging Libraries, and are able to deliver systems ranging from simple capture software through to more sophisticated applications that interface with other machinery, or that authenticate captured images using digital signatures. Automated Vision InspectionManual vision inspection is often associated with a host of problems, such as operator fatigue, eye strain and variations in acceptance levels. Automating such inspection can produce significant benefits, alleviating the problems associated with manual inspection, frequently at considerably lower cost.
WyeTec engineers can advise on all aspects of the Machine Vision solution, including the optimum
lighting design, the selection and control of specialist cameras and, of course, the back end
software to provide the information that your situation requires. In some cases this may be
simple acceptance or rejection of an item, based on some pre-defined criteria, but in others
quantitative measurements may need to be made and fed back to the production equipment to perform
a process control function. |
