Machine vision system for production lines is 11 times faster

System enables previously impossible inspections to be performed with a single camera, and lets users combine up to four 5 megapixel cameras to allow high-definition inspections of up to 20 million pixels.

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 a single 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 (640×480) and high speed 2 Mega Pixel (1,600 x 1,200), which can transfer images in 4.7ms and 29.2ms, respectively. Each camera type is available in both color and monochrome models.

An expandable controller architecture allows users to increase the flexibility of their 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; these also filter out glare or other background noise so that only the flaws are detected. The new Fine Color Processing function directly processes full-color information to extract defects from backgrounds with pattern or illumination variations.

CV-5000 Series controllers come with built-in statistical functions so users can view inspection results in real-time. The on-board image archive can store up to 1,024 (past) inspection images that can be reviewed at a later time. Combining these two features allows for detailed analysis of product result trends and failure conditions, making it easier than ever for users to fine tune their program tolerance and settings to improve yield rates.
