STANDARDS DEVELOPMENT


while at the same time doing everything to maintain market access for European machine vision players to all parts of the world.


What is the background behind users of the EMVA 1288 standard being asked to relicense? Tis is part of the new set of rules, but also, with release 4.0 of EMVA 1288, the EMVA granted a transition period of one year for relicensing that expired in June. Terefore, since 21 June, datasheets in which data is designated as EMVA 1288-compatible and marked with the EMVA 1288 logo may only be published if the new EMVA 1288 licence has been applied for and approved by the creator of the datasheets. I want to point out that use remains free


of charge under the new licence, as it has been for the last 17 years. Te aim is to have control over how the standard is used such that only those parties using the standard in the proper technical and legal sense are guaranteed by the licence.


Do you require something similar for GenICam? Not exactly. Te general conditions for participation in the GenICam standard working group have changed within the new legal framework, which requires a re- registration for all participating company representatives. Being the host association of the GenICam working group, the EMVA adjusted the conditions to those already


established in standard working groups hosted by other associations. Tis involves a small fee for working group members. However, use of the GenICam logo, as well as the reference implementation, remain free of charge under the new licence, as it has been for the last 19 years. All necessary application forms for


relicensing can be found in the standards section of the EMVA website. Tese two measures for EMVA 1288 and GenICam are part of the implementation of the new standards development policies. In the forthcoming period, all current members of hosted working groups will reapply for working group membership and, through this action, will be protected by the newly adopted development policies. And there are more actions to come.


Can you specify these actions? One major benefit of having standards is the compatibility of the services and products among those who use the standards. As such, it is the responsibility of the hosting institution to keep and maintain the compatibility level. Te longer a standard is used in the market and developed, the more important this issue becomes. For GenICam we intend to implement a GenICam validation framework, where every user is validated to reconfirm the standard criteria and thus the technical compatibility of the product. Tis validation process will be implemented later in 2022 and through the next GenICam meetings.


Last year, the EMVA and the Khronos group joined forces to develop an open, standardised embedded camera API. How has this progressed? A very interesting aspect of this collaboration is that two different communities have been brought together. While many machine vision companies have a strong background in industrial automation, the Khronos group represents platform players, chip providers, as well as companies operating in diverse areas such as consumer devices, medical, AR/VR, and automotive technology. We are happy to announce that an


exploratory phase has been completed and a standard working group has been established with Khronos. Currently the working group consists of 71 people representing 43 companies and institutions. Te cooperation between EMVA and Khronos will continue throughout the design phase, as a formal joint initiative of the two organisations. Importantly, this means the EMVA is able to participate directly in the working group, as well as influence design development and contribute to the new standard. Tis entire process represents a major


new direction for standardisation in embedded vision through cooperation between leading associations and their members. Te EMVA has paved the way for its members to take part in the biggest effort on embedded vision standardisation of the last decade. O
