running and generating a pointcloud (.las) about livox_horizon_loam HOT 2 OPEN

Are you familiar enough with ROS to know that it publishes ‘messages’ on ‘topics’? - Mark West On Jun 12, 2020, at 4:38 AM, cfessler <[email protected]> wrote:  i successfully installed the loam following the guide, but now i am stuck a bit. Can you guide me how to generate a pointcloud out of that. as far as i have understood i have to choose the ros every time i open the console: source ~/catkin_ws/devel/setup.bash then i run roslaunch loam_horizon loam_livox_horizon_imu.launch to get the data from lidar and IMU? whilst rosbag play YOUR_DOWNLOADED.bag - in my case rosbag play 2020_open_road.bag will add the lidar data to the file? i do not really get it and to be honest i did not unterstand the ros documentation. So this is the point where i am standing, is there someone able and willing to point me into the right direction? When looking for the points mentioned i found the line rosrun pcl_ros pointcloud_to_pcd input:=/velodyne/pointcloud2 which looks like refering to the subscibe to /velodyne_cloud_registered and register, but i dont get it and i dont really get how the magic works. And what ist meant by registering them together? Anyone who is able to help me with that? — You are receiving this because you are subscribed to this thread.
