The result of paper

[lhthq]

Thank you for your excellent work. We have attempted to replicate the experiments as per the instructions outlined in the README file. However, we observed significant discrepancies in the obtained metrics compared to the reported results in the associated research paper. Specifically, the differences are on the order of magnitude. We propose the issue to seek guidance on potential factors or considerations that might account for these variations. Thank you!

Hello, from your description I feel that you at least successfully run the program, I would like to ask when I run GTmapping_nclt.launch, there is a problem with the phrase "~~~~/home/USER/roll_ws/src/FAST_LIO/ doesn't exist" as follows,Do you know what the cause is and how to solve it, thank you very much

It seems to that the launch file contains another /lasermapping node. But I do not meet this issue.

Thank you for your answer. I have solved this problem,but I ran into another question about localization test. When I run loc_nclt.launch,It worked successfully. But when I rosbag play xxx.bag, the following error will be reported

The picture may not be clear, it's "REQUIRED process [roll_mapOptmization-3] has died! process has died [pid 29535, exit code -11, cmd /home/sunsh/roll_ws/devel/lib/roll/roll_mapOptmization __name:=roll_mapOptmization __log:=/home/sunsh/.ros/log/7223798e-decf-11ee-b9c7-74563ca50fba/roll_mapOptmization-3.log]. log file: /home/sunsh/.ros/log/7223798e-decf-11ee-b9c7-74563ca50fba/roll_mapOptmization-3*.log Initiating shutdown!" I would like to know if you have encountered the same problem, or if you know the cause of this problem and how to solve it, which is important to me, thank you again

Hi, I'm experiencing the same problem when launch GTmapping_nclt.launch and loc_nclt.launch, can you please tell me if you have a good solution for it. Thank you!
