Bad loop closure results

[Yan, Qiao]

Hi @ziv-lin Thanks for your great work!

I collected my own data indoors with Livox Horizon and ran your code with "roslaunch loam_livox rosbag_loop.launch".
However, it seems that the "loop closure" did not achieve with good result. There are clearly a few drifts in the mapping.

Any solutions ?
Thanks in advance.
