OMNIVIEW™ TECHNOLOGY for high-speed, non-stop inspection of randomly oriented cylindrical containers
Wednesday 26 December 2007Imagine how useful it would be to inspect the entire cylindrical surface of bottles, cans, vials, or cosmetic containers without the need for orientation or accurate positioning. This seemingly impossible capability is what OmniView™ technology from Cognex provides. OmniView uses 4 cameras to obtain a 360-degree view of all features on the entire surface. It can read barcodes, verify text, inspect graphics and measure features at production line speeds of up to 1,200 parts per minute.
OmniView is a revolutionary vision software technology that uses images from multiple cameras to create one seamless and undistorted 360-degree image of any cylindrical surface. Obtaining such an image without OmniView requires stopping and rotating each cylindrical object in front of a line scan camera—a complex process that is too slow for today’s high-speed production lines.
Instead, OmniView uses images from multiple area cameras positioned around the cylindrical object to instantly generate a virtual 3D surface model. OmniView then creates a seamless, undistorted, “unwrapped” image of the complete surface to which optical character recognition (OCR), barcode reading, and other machine vision software tools can be applied. Eliminating the complex and expensive requirement to mechanically spin parts in order to inspect them dramatically reduces complexity, lowers cost and significantly boosts throughput.
“In the food, beverage, and pharmaceutical packaging industries, OmniView allows customers to more cost-effectively avoid mislabeling errors, comply with evolving safety standards, and ensure product quality,” said Marilyn Matz, Cognex Senior VP, PC Vision Products Group. “OmniView’s non-stop, no-spin inspection of directly-printed or labeled cylindrical containers is ideal for achieving accurate, reliable non-contact, 100-percent inspection on even the fastest-paced packaging lines.”
