I have the same problem that the [velodyne_nodelet_manager-1] process has died

Did you try the ways in #4 ? In particular, try docker.

Regarding the paper, I think I can send you it if you tell me your official address in your institute or organization.

I don't find the problem again , may be I adjust optimize iterations param

[koide3]

@autoperson , How did you change the iteration param? I want to figure out what causes this problem...

[autoperson]

I set the iteration param with 512

[koide3]

@autoperson , Thanks for the information. I'll try the setting...

@autoperson Where did you set the iteration param?? Was it the max number of ndt iterations or the number of iterations done during optimisation?

[autoperson]

It was the number of g2o optimization iterations in code @ekow-mensah, you can find other answers of 4# question.
