How USB is Shaping the Future of Machine Vision

Here at L-com we are a member of the AIA (Automated Imaging Association) trade group, the world's largest machine vision trade group. As a member we feel that it is our duty to give you some insight on how advances in USB 3.0 technology are affecting the growth of machine vision.

 

First of all-- for those who don’t already know, machine vision is defined as the methods and technology used to provide imaging-based automatic inspection and analysis.

 

Machine vision systems use cameras and image processing software to perform inspections, similar to how human inspectors on assembly lines visually inspect the quality of the products. Examples of applications where this takes place include automatic inspection, process control, and robot guidance in industry.

 

Machine vision inspection plays an important role in achieving 100% quality control in manufacturing. This reduces costs and ensures a high level of customer satisfaction. However, one of the main challenges designers face in machine vision today is market demand for HD imaging and the need for greater bandwidth based on increasing sensor resolution and frame rate.

 

Current systems are forced to compromise between image quality and compression. Higher levels of compression limit the accuracy and performance of machine vision systems.

 

But have no fear; this is where USB 3.0 comes to the rescue.

With USB 3.0, designers now have additional bandwidth at their disposal. USB 3.0 is fast -- with a 5 Gbps data rate, which is a 10x increase over USB 2.0 (480 Mbps). The increased bandwidth substantially reduces the time required for transferring large amounts of data or video.

 

As the EE Times stated it, designers can more readily increase image resolution and frame rate with greater bandwidth while still preserving image quality. Without the need for compression, designers can also reduce the amount of memory required in systems.  This translates to a lower BOM, smaller PCB, and reduced power consumption.

 

L-com offers a large variety of USB cables, and our cables are manufactured per the mechanical requirements of the USB 3.0 Vision standard. In addition to supporting the machine vision camera market, the screw mount hardware required for USB 3.0 Vision cables is beneficial in many other applications where standard USB connectors can become dislodged due to jostling, vibration, or other factors.

DJ Drops Mad Beats But Not His USB Connection

A Testimonial from the Nerdy DJ (DJ Forge)

 

 

A USB dropout.

 

The mixer isn’t communicating with the software and silence starts to creep in as people halt to a standstill on the dance floor. Alternative sound must recover or else dead air lingers until the equipment is either trouble-shot or rebooted.

 

This is a DJ’s worst nightmare. Everything counts when you’re mixing in a club or at a large show. A lag or halt in the music is a death knell.

 

That’s why Jordan Chavis, better known as DJ Forge of North Carolina, must rely on fail proof equipment (including high performance cables) to run his shows. According to Chavis, anything you can do to avoid that dropout scenario is a win. Having the right USB cable is just a small but important part of his set-up.

 

So, Chavis turned to L-com’s Right Angled USB Cable to run his DJ mixer. “You can tell the difference between a high quality cable and cheap cable,” Chavis said, “And this one has been really reliable.”

 

Chavis discovered L-com’s Right Angled USB Cable when he was faced with an unusual USB port placement on a trial piece of equipment. On his blog called The Nerdy DJ (for working DJs, by working DJs) Chavis and his friends did a comparison of two mixers and wrote about it in Rane Sixty-Two vs. Pioneer DJM-900SRT. Since the USB port was on top of the Pioneer DJM-900SRT mixer instead of in the back where it normally is, he decided that he needed a cable which would be secure yet flexible.

 

Armed with his Right Angled USB cable, Chavis is confident he can run his shows without skipping a beat.

 

“This cable is something that my DJ friends and colleagues and I will recommend to use for all types of DJ mixers or DJ controllers,” said Chavis, “Because even if the port is in the back, it’s convenient to have the right angle for connection security and it get’s the cable out of the way.”

 

In addition to providing equipment reviews like the Rane vs. Pioneer demo, Chavis’s website is a community for DJs to turn to for career advice, how-to’s, maintenance tips, and more. Chavis aspires for Nerdy DJ to be a place where DJs are collaborating and a site that every DJ wants to check when he or she wakes up in the morning. Alongside playing weekly shows and serving as the official UNC DJ, Chavis has focused his time working hard on Nerdy DJ since last October so that it can be a hot spot for new and old DJs alike.

 

Chavis has opened for some of the biggest names in hip-hop including Jay-Z, Young Jeezy, Fabulous, Clipse, KRS-One, Ghostface, Method Man, and more. He discovered his love for DJing back in college as a computer science major, when a roommate brought back a turn table to their place.

 

“I got nerdy about DJing instead of nerdy about coding,” said Chavis.

 

In the upcoming weeks you can find DJ Forge at events in some of his favorite spots in NC. Chavis said he is also starting to throw hip-hop shows once a month and hopes to narrow his focus on growing in his career, as well as travelling more. Keep a lookout for him in Tokyo or elsewhere in Japan in the near future!
