Industry's fastest compact vision system?

05 November 2013

With a high-speed image bus, four-core processing, a new and exceptionally efficient vision algorithm and fast EtherCAT communications, the new FH compact vision system from Omron is said to set new standards for speed, performance and versatility.

Tests carried out by Omron confirm that the vision system is the fastest of its type currently available, helping users to achieve shorter machine cycle times, even in difficult operating conditions.

Designed for fast efficient operation at every stage – from image capture to data output, Omron’s new vision systems are intended for seamless integration with PLCs, motion controllers and robotic control systems, and are suited for applications in high-speed manufacturing machines of all types.

The vision system is also compatible with Omron Sysmac Studio Automation software, so only one software package is required to set up all of the major components used in an automation system.

At the heart of the new FH vision controllers is the company’s Shape Search III vision algorithm which is said to be up to nine times faster when carrying out searches than conventional algorithms. This enables fast, precise measurements to be made even if images are out of focus, or if the targets are randomly positioned, randomly rotated or overlapping. This performance is achieved without the need for user-dependent calibration.

Because of its efficient image handling characteristics, the new vision system can support multiple high-resolution cameras with no degradation of performance or image capture speed, allowing it to handle complex inspection tasks and, in some applications, enabling a single vision controller to be used where previously several would have been needed.

Omron FH compact vision controllers incorporate support for the EtherCAT machine control network, allowing communication cycle times as short as 500 µS to be achieved as well as allowing the implementation of motion control synchronised with the communication cycle.
