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:

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:
In this article we will concentrate on one of the most commonly used techniques, laser triangulation.
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:
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.
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 
Link 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.
After 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
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.
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
So, we’re at the end of the year and have arrived at our final post for 2012. I’m not promising brilliance, mostly just a really quick review and the opportunity to thank our readers and contributors for their continued support and to wish everyone a safe and happy holiday. My hope is that you are able to greet the new year refreshed and ready for a successful year of innovation.
Although I live in Montreal where the chilly winter weather gives us an excuse to stay indoors, the holiday season, regardless of your local climate, is another good reason to hunker down by the fire (or swimming pool?) and catch up on your reading.
Here is a selection of interesting industry articles that were published about us recently:
Let us know what you think and whether you have any similar reading material of your own you’d like to share in the comments below.
Happy Holidays!
While I could post on B Grey’s blog and agree that a program of study for implementing machine vision is a great idea, I believe there’s more
to say. That the AIA’s the organization to lead the charge with their Certified System Integrator Program is interesting to me – I remember how excited Rusty Ponce de Leon was when it was in its formative stage. It begs a couple of questions – does the initiation of the AIA’s program Continue reading
