Hello Kailegh, Have you found something that worked better than BLAM! ? John

Hello Dan, I also would like to export my registered point cloud from RVIZ. Did you ever find a way to do that? Also for what it is worth, I created my registered point cloud using BLAM! from Erik Nelson, it has worked nicely. https://github.com/erik-nelson/blam

Hello Kailegh, I got sifdetracked but I am back. I have made some progress, I got BLAM! installed (not trivial) and it is working pretty good now. I am trying to select and export a group of points in RVIZ that were created by BLAM! so that is where I am at right now. Have you had any luck?

Hello chambana, I have the same question as you. I was wondering if you had any luck with the suggested tool?

Thanks, John

Hello Nikka, Sorry for the late response, I was away for the holidays. I have been trying to use BLAM, I am not getting good results at all. The successive point clouds are not registering properly. I am going to try and adjust the number of iterations that ICP algorithm takes, hope that will help.

Thanks for the input. I have been making some progress. What I need to do at this point is extract the pcap format packets out of the bag file. I am looking around, I will see if I can find a way to do that.

Hello, I am very new to ROS so excuse my simplicity. I have Velodyne Puck point cloud data that I would like to use to create a 3D map. My issue was that I was moving the puck as I collected the data and I have no odometer data. Would I use a ICP program? And if so any recommendations? I saw that Willow Garage has one, I assume that it is a good package.

Thank you so much. John
