So far we have two problems, if we want to keep on working with Reality Capture:  
(-) export camera positions (alignment) into Colmap compatible format  
(-) export images as cropped without black bars:

> To me it clearly is a RC bug that these black strips are present with Fit: Inner Region parameter during undistortion. If you want to remove these black strips, you can do so with the below kapture utility - based on a kapture project. (with the kapture library, a bit verbose, but seem to do the job). Please follow the [full workflow](https://twitter.com/jo_chemla/status/1698985750367281499) for first converting bundle to kapture, then kapture to colmap.
