How do I create and map pointcloud data?
Hello, I'm new to ROS (did the basic/intermediate tutorials) and want to try and map pointcloud data.
My question: How do I generate pointcloud data (preferably without an actual camera/robot - a simulation) and map it (using rviz?)?
My thought process on the steps to do so (this is what I think I need to do - could be wrong):
1.) Create catkin workspace
2.) Create 3 nodes in my package (point cloud generating node, mapping node, display node)
3.) Send pcl data (Once generated) to mapping node (and map it somehow), then mapping data to display node (and display it somehow)
If you know of any good tutorials on how to do this, please link them. Or give me your own tips/guide.
Additional info:
I have my catkin workspace set up
I downloaded the sample bag file from http://wiki.ros.org/slam_gmapping/Tutorials/MappingFromLoggedData#download and tried to display it on rviz to no success
Now I'm here :)
Thanks for the help in advance!
