Hi Ahmad, this feature is on our internal roadmap and we are working on it.

Hello Ahmad.  
Could you share how it is done. I have downloaded RealityCapture and Jawset Postshot. I was able to use output from COLMAP for Postshot but struggle to find out, how i can use RC for Postshot.  
Could you please explain it to me? I really dont know what to export. If you could help i would appreciate your help. Thanks!

Really great to hear the team is working on it, especially since the kapture workflow has been described a year ago in this thread - and that the black strips bug on undistorted camera export has been fixed in an earlier version, this workflow is now even simpler.

For anyone watching this thread, colmap export directly from RC is now live in latest release RC 1.5, see [changelog](https://www.capturingreality.com/release-notes)

Added a feature-request [here](https://forums.unrealengine.com/t/registration-export-allowing-exporting-rcinfo-companion-especially-for-shifted-project-output/2156624) to allow exporting rcinfo xml for registration exports

Hello everyone, as mentioned in @jochemla’s previous post, we introduced the Colmap export option and the Radiance Fields transform.json export option in the latest RealityCapture 1.5, which was released on November 20th.

Currently, the Colmap exporter always exports undistorted images based on the undistortion settings you specify in the export settings.

Is this sufficient for your workflows or would you also prefer to have an option to export the Colmap txt files that correspond to the original distorted images?

The Radiance field transforms.json export supports both original distorted images and also undistorted images.

Also, any other feedback you might have will be invaluable. Thank you!

Best regards,  
Jakub

Hello liang, this is a question for Unreal Engine forum, not RealityCapture.

On our side it would be useful to support exporting input images as either undistorted - like now - or original raw (distorted) + colmap text files with registration intrinsics per input.

This would help avoid duplication of almost identical data (original and undisorted input images) when we support real-time image undistorting (JS in-browser, or on unreal-engine) via libs like [mbredif/photogrammetric-camera](https://github.com/mbredif/photogrammetric-camera)

Thanks for the feedback @jochemla. We’ll look into that.
