Hi,

1) Can you rerun rtabmap node with --udebug argument? I suspect it is creahsing in the cv::hconcat here. However, based on the check if they are empty, it should not happen. The debug log may help to understand which line is problematic.

2) It is not possible. For more info, you are dealing with two different SLAM approaches, if they don't detect and close loop closures exactly the same way, the two maps will drift from each other.
