Lights, Camera, Algorithms: The Basics of Machine Vision Pattern Matching

We humans learn to recognize patterns from the day we first open our eyes. That’s a bird! That’s an airplane! Those are the letters A, B and C! If we couldn’t pick out specific objects from our surroundings and categorize them, our sense of sight would be of little use. Machine vision systems also need to be able to find and recognize patterns.The first step in any machine vision task is pattern matching, i.e. locating an object within the field of view based on an expected arrangement of shape attributes like edges. How does this process work?

The Coevolution of Miniscule Laser Markings and the Trusty Industrial Readers That Decode Them

Bumblebees and flowers, ants and acacia trees, industrial code readers and laser markings… What do these three pairings have in common? The answer is that they’re all examples of entities that have undergone coevolution. Granted, the latter duo isn’t exactly subject to the pressures of Darwinian natural selection out in the wild, but who’s to say that the demands of industrial automation on traceability technology aren’t at least somewhat akin to the Darwinian process?

Like Oil and Water: How Two Non-Mixing Fluids Give Liquid Lenses Their Power

Liquid lenses are rapidly gaining popularity within the industrial sector thanks to their speed, flexibility and reliability. Let’s look at how this whimsical-sounding concept has turned into a solid technology with awe-inspiring capability.

Grasping the Importance of High-Performance, Industry-Ready Handheld Scanners

Handheld barcode scanners are essential whenever specific products, clinical samples or work-in-progress (WIP) parts need to be reliably tracked without the luxury of a fully automated system. Many things on the factory floor can be automated, but other things, such as external deliveries, are unpredictable and tricky to automate. In these situations, humans must take over the responsibilities of track, trace and control (TTC).

Track, Trace and Control: The “Past, Present, Future” Reading for Industrial Works-In-Progress

To develop smart solutions for slow-moving manufacturing systems, industrial automation experts put heavy emphasis on the concept of Track, Trace and Control (TTC). Used primarily to manage work-in-progress (WIP) components, TTC can be likened to a “past, present, future” reading for each part. It’s an essential management tool that allows manufacturers to make decisions in real time and avoid unnecessary costs in money and time.

Why Smart Cameras Are Today’s Fastest-Evolving Machine Vision Technology

The vision market is moving forward at lightning speed, and smart cameras are leading the way. These compact devices have become the focal point for technological advancements in the field of machine vision, yet PC-based machine vision systems are still more powerful. Why are vision engineers turning their attention to smart cameras?

Setting Up a Complete Machine Vision System

Machine vision systems are an essential component of industrial automation solutions. Although there is a lot of variation among machine vision systems, they all include certain essential components to perform the basic functions of capturing and processing images, and then delivering an actionable result based upon features in the visual data.

Validation ≠ Verification! Use VMI to Avoid Costly Recalls

You can read your own barcodes. That’s great – your work would come to a screeching halt otherwise. But have you thought about the people who handle your products further down the chain of distribution? They’re probably not using the same scanners you’re using, and it could be risky to assume that they can read your codes. If they can’t, it will cost you.

How UDI Compliance Can Be The Key To Digitally Transforming Quality Assurance

2020 is a year etched into the minds of many medical device manufacturers (MDMs). Not only does the United States Food and Drug Administration’s (FDA) UDI compliance date for Class I and non-classified devices fall in that year, it’s also the year the recently approved European medical device regulations (MDR) go into effect. These impending deadlines have MDMs taking a long, hard look at their labeling to make sure they can meet the various labeling requirements in the countries where they do business.

Dashing Through the Warehouse: How Barcodes Bring Holiday Gifts to Your Doorstep

A century ago, today’s process of getting your holiday orders delivered would have seemed as magical as Santa’s reindeer-driven sleigh. What prevents the holidays from turning into a holy mess? You can probably guess – it’s our good friend the barcode!

Keeping Medical Devices Safe and Reliable: The New MDR and IVDR Regulations

The Medical Device Regulations (MDR) and In Vitro Diagnostic Regulations (IVDR) will be implemented gradually over the next few years, but affected manufacturers will need to get started on compliance as soon as possible due to the significantly expanded requirements. Although it might not be immediately apparent, these new developments on the European market have a lot to do with Omron Microscan’s world of barcode scanning and imaging devices.

The Ubiquitous Barcode

They’re everywhere! Whether they present themselves as zebra stripes or pixelated whorls, there’s just no escaping those pesky little patterns. Yet barcodes simplify life in many ways, and the concept of the barcode itself is really quite simple. Though the specimens may look complex, they’re all basically machine-readable representations of whatever data needs to be recorded and tracked.
