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.

Easing into 2013 with another Machine Vision Must-Read List

Feb 1, 2013
Heather

The first weeks of 2013 have proven to be quite busy here at the office. And yet I am amazed at the number of prolific writers we have at our company, especially considering all of the other work they must attend to. And when our engineers and scientists are not writing, they are being interviewed by editors from the industry’s leading trade publications. You may even recognize some of their names popping up in articles and the blog. Talk about dedication!

Here are a few links to recent articles written by or about us:

  1. Vision Keeps Pace with Growing Metrology Demand – AIA Vision Online
  2. Blazing the GigE Vision Trail – Quality Magazine
  3. Vision integration speeds production, cuts waste for plastics manufacturer – Control Engineering
  4. Machine vision standards definition moves forward with establishment of new forum – ITS International
  5. The Eyes of the Mars Curiosity Rover – NASA Tech Briefs
  6. CMOS Sensors Increase Inspection Speed and Accuracy – Photonics Spectra

Hopefully this will keep you busy until the next installment in a month or so. Until then, feel free to drop me a line in the comments section if there’s a topic you’d like to see us write on.

A Second Life for Camera Link

Jan 29, 2013

In my previous post, “Will USB3 Vision overtake Camera Link?”, I questioned the ability of Camera Link to face the challenge raised by USB3 Vision. Since its introduction in 2000, Camera CameraLinkLink has reigned as the “go to” standard for real-time data acquisition from a machine vision camera. And for many years, commercial interfaces such as Firewire, GigE and now USB3 have been raising the bar on  acquisition throughput without a frame grabber. For many of us, this brings the equation of cost vs. bandwidth to the forefront of the interface debate.

Will USB3 Vision overtake Camera Link?

Jan 23, 2013

USB3After being very visible at the Vision Show (Stuttgart, November 2012), AIA USB3 Vision 1.0 will be released during Automate 2013 this week. This is a significant event for the Machine Vision industry. As I mentioned in a previous blog post (A New Predator in the Machine vision World), USB3 is an attractive medium for real-time image transfer from cameras: low system cost, native robustness and good transfer speed at 5 Gbps (which will probably end-up in the 350-400 MB/s range in practice). This will be a strong contender for Camera Link BASE. But there is more… Continue reading

A Preview to Color Machine Vision Tutorial @ Automate 2013

Jan 18, 2013
Ben

On January 23, I’ll be presenting a tutorial on Color Machine Vision at the AIA’s Automate Show. Attendees who pass a subsequent examination will become Certified Vision Professionals (CVP). Here are a few key points to pique your interest in perhaps attending said course. Hope to see you there. 

Every vision system requires 3 things – 1. a source of illumination, 2. material to inspect, and 3. one or more sensors for measuring the illumination reflected or transmitted from the material being inspected. A simplified model of this process is that the spectra (distributed by wavelength) of these three components are multiplied together and integrated over a wavelength to give an output value from a sensor.

Smart phones might teach us a lesson

Jan 8, 2013

The Holiday Season is the time of the year when parents everywhere attend their children’s mini-shows at school. My daughter sings in a children’s choir and I took the opportunity in December to take in her Christmas performance. I am not here to report on the tears she and her classmates were able to draw from my eyes, but more on a radical technology change I’ve noticed taking place and its impact on these popular events. After all, I am a father and an engineer (the former taking precedence!). Continue reading
