Barcode Reading – Machine Vision vs Supermarket Checkout

May 7, 2013

Barcode reading is widely used in Machine Vision (MV) for part identification. But is there a unique solution that works for all scenarios? I frankly doubt it. The question still remains – why is barcode reading so difficult in MV? It’s true that handheld readers used at the supermarket checkout seem as easy as 1,2,3… that is, of course, after the cashier carefully stretches and rotates the package until it finally beeps! Now imagine a fully automated system repeating this task 20-30 times per second? Now, you’ve got the idea. Continue reading

Light In, Light Out Cameras – Fiber Cable as a Game Changer in Machine Vision

Apr 29, 2013
Mike

It’s time for the machine vision industry to literally see the light and start to leverage the advantages of fiber optic technology.

Let me shed some light on the subject for you.

Increased consumer demand for internet content has spurred the major telecoms to bring fiber into your home at low cost. In short, they’ve decided that Coax cables no longer meet the cost/performance criteria. I’d like us to consider then, how this might also represent a game changer in the machine vision industry.

Social Media – More Than A Daily Dose of Machine Vision

Apr 12, 2013

dalsabookmark and shareEven though I’m considered a techie guy (I won’t mention how many Apple devices I own ;-)), I am still a bit “old school” with respect to social media. I don’t tweet, or “whisper”, I’m not on Google+, and don’t try to find me on Facebook. What I am hooked on is LinkedIn. Why? Because I am always looking for new sources of technical information regarding the Machine Vision industry. LinkedIn has a lot to offer in this category. Continue reading

Spring has sprung! Or has it?

Mar 30, 2013
Heather

If you’re still waiting for the ice and snow to melt like I am, then you may find yourself stuck indoors for just a little bit longer. While you’re biding your time, I’ve prepared a light sample of what has been published lately regarding our imaging experts doing what they are passionate about. Over the past couple of months, we’ve been busy attending trade shows, fielding questions from trade magazine journalists, and writing our own articles. Have a look at what we and other industry experts are saying in the articles below:

1. Interviews from Automate 2013 - Robotics Tomorrow

2. Adding a Splash of Colour – IMVE

3. Who Needs Frame Grabbers, Anyway? – Quality Magazine Vision & Sensors

4. Mission to Mars – INSPECT

There’s more where that came from, but let’s wait until we’re stuck inside during those April showers. See you next time and happy reading!

Machine Vision Design for Performance and Cost

Mar 28, 2013
Nixon

We all want to pay as little as possible for the things we buy.

  • Sometimes this means we only purchase for the performance we need. We don’t purchase top grade gasoline just because the oil company says it will enhance our engine’s performance.
  • Sometimes this means we purchase what is already available in the mass market. We don’t usually custom tailor our clothes, because mass-manufactured clothing is often good enough.
  • Sometimes this means we forego service and support. We don’t fly first class because we can live without the pampering.
  • And sometimes this means that we purchase from a cheaper source. We buy produce shipped halfway around the world because it costs less than our local produce.

One for All, and All for One – A Flexible Approach to CMOS Line Scan Design

Mar 19, 2013
Roula

Our internal projects typically have names that are more “fun” than the part numbers that end up in our datasheets. I’ve been involved in projects with names ranging from star constellations and wine varieties to superheroes! A while back, I started working on a project called Cardinal. I didn’t think much of the name… until I saw the die label on the CMOS line scan sensor I was working on:  Porthos. I then came across Athos and deduced that Darta was none other than d’Artagnan. What could have inspired that? Continue reading

The Smart Car Project

Mar 12, 2013
Glen

Despite the astonishing advances in technology over the last 50 years, we don’t often combine these advancements into a singularly-focused, major project – something big.  moon_trimThe last one was the Apollo missions to the moon, where we used technology from many sciences such as physics, engineering, materials science and energy, to send a person to the moon and return them safely to earth. This was, and remains, a remarkable achievement of humanity. It was also the genesis of many of the cooler gadgets we use today.

Six more weeks of winter? Another reading list to help get you through.

Mar 4, 2013
Heather

In keeping with my weather theme, it amazes me how every month of the winter seems to inspire an endless supply of conversation topics. With weather systems that are constantly changing, it’s a wonder we have anything else to talk about. I think we find ourselves alluding to it often, at the risk of seeming obsessed, because the winter weather in certain parts of Canada can be rather extreme at times, going from sunny blue skies at 30 below zero to white out blizzard conditions. And as the winter weather is constantly changing, so too are the topics we write and are interviewed about. Luckily enough, we are well equipped with a diverse group of in-house experts who can answer almost any question or figure out any problem a trade journalist throws their way.

Here are a few of the magazine articles that included us last month: Continue reading

Spectral Cognisance 4 – Is Lux more than Luxury?

Feb 15, 2013
Matthias

Coming from a Machine Vision World, “Lux” and Human Vision have been a mystery to me for a long time. Thankfully, we have had some customers in the application of human vision and I’ve been able to remedy this situation. Tell me what you think…
Following the Spectral Cognisance Series, consider the following graph:

Figure 1: Black Body Emission, Photoptic spectrum (currently in e-), sensor QE

3D Laser Triangulation Calibration

Feb 5, 2013
Raymond

In many applications, 2D cameras are used to produce 3D imaging for general purpose inspections. There are many applications that benefit from 3D inspection, including reverse engineering, electronics, food and auto parts inspection, and recreational or sport simulation.

There are many ways to use 2D cameras for 3D inspection:

  • Laser triangulation using a 2D camera and a laser
  • Stereoscopy using two 2D cameras
  • Interferometer using a 2D camera and several optical devices
  • Scanners using a 2D camera
  • 3D dedicated software using a grey level image to obtain 3D measurements

In this article we will concentrate on one of the most commonly used techniques, laser triangulation.
