Industrial image processing I
ndustrial image processing has long been established as the standard tool for quality assurance. Two trends are now
driving its development ahead: the accelerating pace of automated production, and the increase in quality requirements. The critical factor in meeting these challenges is software that can keep up with developments in optical sensor technology, cameras, interfaces and hardware. The Kistler Group has responded by offering KiVision: innovative image processing software that features user-friendly tools and optimised algorithms – the easy, reliable way to accomplish the demanding tasks involved in this application. As an added benefit, KiVision can also integrate customers' individual new requirements as well as highly complex application-specific routines. The phenomenon we are now seeing is
cer tainly not a new one: any provider who offers a solution that simplifies difficult tasks or reduces the time required for them will inevitably trigger new requirements and expectations. The triumphant progress of email, for instance, has generated sky-high expectations for response times from recipients, with an enormous increase in the volume of messages sent. These developments are prompting email users to demand efficient filters and other helpful functionalities.
‘‘ Customers who have the appropiate
systems and software are now independently able to perform many of the tasks that were still reserved for specialised industrial image processing providers a few years ago Industrial image processing has experienced
similar developments in recent decades: there has been significant progress in measuring and testing series par ts including turned, punched, pressed and plastic components. Automatic image processing systems are now in widespread use for these applications, and they represent a major success factor for production automation and quality assurance in par ticular. Thanks to their speed and cost- efficiency, for example, they allow 100 per cent inspection which – unlike statistical monitoring – can also detect sporadic faults. At the same time, these systems are vastly superior to costly manual testing methods that are vulnerable to errors. These are critical advantages in view of the growth in quantities manufactured by industrial producers and the sharp increase in quality
requirements. Such trends mean that manufacturers need high-performance, high- precision automatic image processing systems if they are to keep up with developments in automated production and protect themselves against claims based on complaints.

Users are beComing largely aUTonomoUs The constant increase in requirements for industrial image processing presents a huge challenge for the software. For instance, high- performance automated test systems from Kistler deploy as many as eight cameras that generate ever greater quantities of data. “As a key component of industrial image processing, the software has to play its par t in overcoming these obstacles – and it has the ability to do just that,” according to Ferenc Toth, Head of Kistler Vision Systems in the Kistler Group. Thanks to optimised algorithms, high- performance image processing software such as KiVision can cope with the breathtaking increase in series production throughput rates. Today’s automatic punching presses, for example, quite often operate frequencies of 1,200 strokes per minute – which means that only about 30 milliseconds are left to capture and evaluate the images. By way of comparison: only a few years ago, press frequencies of 1 000 strokes per minute were greeted with amazement. Advances have also been achieved in terms of accuracy.
