Hi Matlabbe,
I'm using RTabMap Desktop to reconstruct indoor environments.
First of all really thank you for your work, it's really amazing.

To accomplish my work, which is not only 3D reconstruction, I use to save the final sqlite DB to extract the information needed to trigger my postprocessing pipelines. Sometimes it happens that the DB contains multisession mapping info.

The question is: I don't find in any place in the DB the transform between map0, map1, map2 and so on...
Is it possibile to extract this info directly from the DB? Could you please help me?

Thanks a lot
Andrea
