Hi. I am new to Autoware. I am currently using Autoware 1.14 on ROS melodic, ubuntu 18.04. I have tried creating 3d map using bag file from demo moriyama file. What I did was that, I upload the bag file on the simulation page using ref button; play for 1 sec, then pause it; I went to computing tab and selected ndt_mapping. I run rviz using the button on the right corner on the GUI. I set the config of the rviz to be ndt-mapping as well. Then, I unpause the button on the simulation tab to continue the running. Basically, I could see the point cloud map result from the rviz. All is well. I followed this tutorial and I successfully created the map: https://www.youtube.com/watch?v=ss6Blrz23h8&list=WL&index=1&ab_channel=%E3%81%86%E3%81%99%E3%81%A0%E3%81%B2%E3%81%95%E3%81%97
However, now, I want to use another rosbag file, which was recorded by other people, not moriyama. It is a 28 GB rosbag file containing LiDAR and IMU scanning data. I would like to create the 3D map by using Autoware, but I don't know how to do that. I tried to upload the bag file on the simulation tab, but it could not show the detail of the bag file after I uploaded it. Maybe it is due to the file that is too big? How can I deal with big rosbag file in simulation? Do I need to do pre-processing steps to my rosbag data before I use it in Autoware for creating the map? Is there any tutorial step by step that I can follow to build this 3D map with our own rosbag file? Thank you.
