Machine vision system enables ‘previously impossible inspections’

Keyence CV-5000 Vision System offers ultra high-speed image processing for production lines. The (11x) high-speed 5 megapixel camera transfers ultra high-definition images (2,432 x 2,050 pixels) in 61.2 ms (16.3 times/sec). This is 11 times faster than previous models, enabling previously impossible inspections to be performed with one camera.

Keyence CV-5000 Vision System offers ultra high-speed image processing for production lines. The (11x) high-speed 5 megapixel camera transfers ultra high-definition images (2,432 x 2,050 pixels) in 61.2 ms (16.3 times/sec). This is 11 times faster than previous models, enabling previously impossible inspections to be performed with one camera. Up to four 5 megapixel cameras can transfer images simultaneously to allow high-definition inspections of up to 20 million pixels, according to the company. The CV-5000 Series also allows simultaneous use of several other camera types. Users can select from 14 models, including ultra-compact standard and Mega Pixel, as well as high speed standard (640 x 480) and high speed 2 Mega Pixel (1,600 x 1,200), which can transfer images in 4.7 ms and 29.2 ms, respectively. Each camera type is available in color and monochrome models. An expandable controller architecture allows users to increase flexibility of systems while reducing costs. Connecting extra lighting controllers or camera expansion units to either side of the base controller creates a new solution without additional PLC programming or wiring. Up to four lighting control units can be attached, each with two lighting terminals, allowing the CV-5000 to automatically dim and strobe up to 8 lights at the same time. The 3 + 1 parallel processing system addresses the heavy processing needs required by high-volume 5 million pixel images, color processing, and advanced algorithms for complex numeric operations. Several new algorithms have been added to detect foreign objects or burrs on irregularly shaped profiles. Algorithms also filter out glare or other background noise so only the flaws are detected. Fine Color Processing function directly processes full-color information to extract defects from backgrounds with pattern or illumination variations. On-board image archive can store up to 1,024 past inspection images.
