Now there is another standard option to Camera Link and GigE Vision. After the Automate 2011 show in Chicago, the CoaXPress standard gained the endorsement from the AIA and EMVA to Achieve Global Standardization Status as announced by the Japan Industrial Imaging Association (JIIA) on March 31, 2011. The right choice depends on the needs of the application; each standard has its own merits. More information can be found in this free e-paper.
Many machine vision systems using area and/or lines scan cameras will benefit from CoaXPress technology. In these systems it is not just about higher data rates, but the combination of high-speed, cost effectiveness, flexible cabling, long transmission distances, and ease of use. There are more technical features that could trigger the use of CoaXPress in some systems, but these are the main reasons.At Adimec we already see two main categories of customers for our CoaXPress solutions.
- The first are the "high-data-rate" customers that would otherwise require multiple CameraLink cables to transport the data from the camera to the frame-grabber. At these higher data rates the maximum travel distance will be short for Camera Link, (less than 10 to 15 meters) and the cables become very costly. A single or twin flexible coax cable reduces the overall system cost. These customers are building innovative new OEM equipment for complex measurement methods in machine vision. An example customer has a system using more than 15, 4 Megapixel cameras with CoaXPress to maximize speed and minimize cabling. At these speeds this would mean 15 x 4 = 60 Camera Link cables. Now they can suffice with simple, more flexible coax cables which is a huge space and cost saver.
- The second category of customer is upgrading existing, often analog, systems with coax cable already installed. These are typically outdoor applications where the signal travels over larger distances such as defense, surveillance and security applications or traffic applications such as license plate recognition.
A discussion about CoaXPress and Camera link HS (HS Link), an emerging interface for very high-end niche applications, is written in a nice article by Greg Blackman in the April/May issue of Imaging Machine Vision Europe:
CoaXPress is continuing its fast pace towards maturity. After becoming a global machine vision standard the first CoaXPress “PlugFest” event will be held at the Image Sensing Show 2011 in Yokohama, Japan (June 8-10). Here, hardware suppliers will be able to verify their CoaXPress implementation and truly carry the CoaXPress name and logo on their products. In addition, JIIA has updated their web site, in particular the English part, to supply more information and news on all of their activities.
We’ve also written a free ePaper where we tried to compare the existing machine vision industry standards, CameraLink®, CoaXPress®, GigE-Vision® in order to facilitate the camera interface selection process. As Adimec we support all 3 current standards in our products – the choice is yours!
