High-speed, high-definition industrial image processing

Previously impossible inspections now can be performed with the Keyence CV-5000 vision system, which provides ultra high-speed image processing for any production line. 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)—11 times faster than previous models.

High-speed, high-definition industrial image processing
Previously impossible inspections now can be performed with the Keyence CV-5000 vision system, which provides ultra high-speed image processing for any production line. 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)—11 times faster than previous models. Up to four such cameras, capable of transferring images simultaneously, can be used to allow high-definition inspections of up to 20 million pixels. The CV-5000 Series also allows simultaneous use of several other camera types. Users can select from a lineup of 14 different models in either color and monochrome models. An expandable controller architecture allows flexibility of the system while reducing costs. Connecting extra lighting controllers or camera expansion units to (either side of) the base controller, for example, creates a seamless solution without (additional) PLC programming or wiring. Up to four lighting control units can be attached, each with two lighting terminals, allowing the CV to automatically dim and strobe up to eight lights at the same time.

The “3 + 1 parallel processing system” addresses the heavy processing needs required by high-volume images and advanced algorithms that perform complex numeric operations. Several new algorithms have been added to detect foreign objects or burrs on irregularly shaped profiles. These new algorithms also filter out glare or other background noise so that only the flaws are detected. The newly equipped Fine Color Processing function directly processes full-color information to reliably extract defects from backgrounds with pattern or illumination variations. CV-5000 Series controllers come with a range of built-in statistical functions that let the user view the inspection results in real-time. The on-board image archive can store up to 1,024 (past) inspection images for review at a later time. Combining these two features allows for detailed analysis of product result trends and failure conditions. www.keyence.com/cv5 Keyence
