Hello,

Are there any current extensions for camera calibration and registration?

I think @drouin-simon plans to implement a Slicer module for it, and collaborators of @tokjun worked on releated topics in the past. They may be able to give you more information.

I will see if it’s being built on the build machines.

Edit: Tests are failing on precursor extension, making a build now to fix tests.

Sorry for the massive delay, tonight’s (tomorrow morning’s) build should show us whether my fixes worked.

Hi Adam,

I can’t get the extension to work on 3D Slicer 5.6.1. Has the extension been discontinued?  
In addition, I was also wondering: would it be possible to implement the kalibr toolbox ([GitHub - ethz-asl/kalibr: The Kalibr visual-inertial calibration toolbox](https://github.com/ethz-asl/kalibr)) as a Slicer extension? I am quite new to Slicer, so before delving into it I would like to hear some feedback.

Thank you

Hi,

Yes, I have discontinued support. I will remove it from the extension index. It wouldn’t take much work to renew, but there wasn’t enough of a need to keep maintaining it.
