Over 60 imaging and machine vision professionals from 36 leading machine vision companies worldwide met under the support of the global Machine Vision associations AIA, EMVA, JIIA, VDMA and CMVU (jointly referred to as G3) in the middle of October in Chicago for this years fall International Vision Standards Meeting (IVSM). The meeting was hosted by Components Express and involved discussions on the development of current standards including the GenICam software standard, and the CoaXPress, USB 3.0 Vision, Camera Link, Camera Link HS, and GigE Vision standards. In addition, a plugfest was held, where products and their compatibility to the standards were tested.
Many of the updates and to the standards are to support 3D imaging and higher data rates when possible. Here are some of the results from the event:
CoaXPress
The CoaXPress working group was in session for 2 days. The group has been working on a maintenance release of the current V1.1 of the standards that is scheduled for release before the end of this year. As a part of this effort it will be possible to use DIN1.0/2.3 connectors with an additional locking mechanism that makes the connector better suitable for rugged environments.
But perhaps even more important: preparations have been made for the next major release (V2.0) of the standard that will increase the speed per cable to 10/12.5 Gbps (from the current 6.25 Gbps). Apart from the speed bump, the new version will add Forward Error Correction, data striping, support for 3D cameras and for GenICam events. V2.0 of the standards is planned for release in Q4 2016. The first products will be shown at the Vision Stuttgart in 2016.
GigE Vision
The GigE Vision group is working on V2.1 of the standard that will include support multi-part (for e.g. 3D video) and new locking types for the RJ45 connector. Also the group is working on improvements on the validation framework to further increase the test coverage. Finally, the working did preliminary work on technologies for next versions of the standard like NBASE-T (for higher speeds over Cat5E and Cat6 cables), additional connectors and improved Wi-Fi support.
USB3 Vision
The USB3 Vision group has been working on improvements in the validate suite, which is used to verify the flawless implementation of the standard e.g. by camera vendors. Another topic of the meeting was work on V1.1 of the standard that will add multiple image streams and the support of 3D images. This next version of the standard is planned for release during Q1 of 2016.
GenICam
The GenICam working group’s main focus is finalizing the GenICam 3.0 reference implementation. GenICam 3.0 is faster and has a smaller footprint in memory than the older 2.X versions. It also adds several new features of which the support of 3D cameras is probably the most important one. Also, GenTL version 1.5 was released.
Camera Link HS
The working group is preparing for Rev.2 of the standard that is mainly focusing on increasing speeds. Revision 2 of the Camera Link HS standard is planned for November 2016.
Plug Fest
The plug fest was as usual an important event during the week. Camera, frame grabber, software and cable vendors worked together to verify flawless operation between all kind of products. The Plug Fest hosted standards of multiple associations: Camera Link HS, CoaXPress, GigE Vision, USB3 Vision, and the GenICam (GenTL) software standard.
Future Standards Forum (FSF)
During the last FSF in London, a study group has been setup to investigate how the current Machine Vision standards fit with the requirements of embedded vision systems. (Embedded vision systems often do not need the long cable lengths, nor the special connectors used in machine vision). Some of the questions for the study group: Should we make a special standard for embedded vision systems? Can we extend a standard that we already have? Should we adopt an existing standard (from outside the MV market) and make it suitable for embedded MV applications? During the FSF the study group reported the current status, plus proposed how to proceed.
As a next step the report will be shared with members of the G3 associations in order to solicit for feedback. In parallel the working groups proceed their work to prepare for decisions during the spring 2016 IVSM meeting in Japan.
Also, the JIIA Optical Interface working group reported about their progress in scouting and testing of optical interfaces for use with multiple G3 standards (Cameralink HS and CoaXPress already expressed their interest). The goal is to be able to select one or two candidates during 2016.
Finally the G3 standards chairs worked on an update of the Machine Vision Brochure that will become available by the end of the year which will include some minor corrections and the latest information on each standard.
