OpenLensIO

[jamesmosys]

Describe the purpose of the group in no more than 4-5 sentences

OpenLensIO is a community dedicated to enhancing interoperability in lens distortion modelling for media production. It formulates a set of standard mathematical models for lenses targeting their application in media production and presents open-source reference implementations for the providers and consumers of lens metadata.

Goals of the working group

• Reach consensus on and publish a generic, practical, end-to-end mathematical model for lenses for use in visual effects and virtual production
• Provide training resources and detailed documentation on lens distortion processes - capture, transmission and application
• Provide open-source reference implementations for lens metadata that can be used by calibration tools, in real- and non-real-time visual effects pipelines, and in live lens data transmission
• Provide a framework for an open and free online lens library that can be contributed to by the community.

Non-goals of the working group

• Infringe on lens, camera tracking or render engine manufacturers' intellectual property or commercial value in lens calibration techniques
• Handle lens distortion outside of content creation / media production verticals

Deliverables

• End-to-end mathematical model for lens distortion
• Reference implementations for capture, transmission and application of lens distortion
• Framework and guidelines for contribution to the OpenLensIO lens library

Hi @jamesmosys - we have scheduled this for March 6, 2024. Let us know if that date works, and please share in this ticket any presentation materials you plan to present. Thanks!

[jamesmosys]

Thanks @jmertic - that date works great. I'm based in the UK. Thanks!

[jmertic]

Great! You can register for the meeting at https://zoom-lfx.platform.linuxfoundation.org/meeting/97880950229?password=81d2940e-c055-43b9-9b5a-6cd7d7090feb

[jamesmosys]

I have a short presentation to give some context if there is time. Thanks and see you tomorrow!

[jmertic]

Sounds great! You should have around 25 minutes for the presentation and Q&A

[jmertic]

Thank you @jamesmosys for the proposal. As discussed by the TAC, please reach out to some of the other groups such as the USDWG Camera SIG to see about potential alignment. Let us know when we can reschedule you to come back to the TAC

Hi @jamesmosys - seeing if you've reached out to the recommended groups and have any updates on how you'd like to proceed.

[jmertic]

Hi @jamesmosys - any updates?

[jamesmosys]

Hi @jmertic - sorry for delayed response. The RIS OSVP group are currently prioritising working on the tracking protocol side of things. This is close to completion and as soon as it is we will be back on to lens mathematics. I'll keep this thread updated with our progress. Thanks.

[jmertic]

No worries @jamesmosys - let us know if you need any assistance or support.
