Edit your launch file. for me it was mapping_horizon.launch
change line 9 from
  1. <param name="map_file_path" type="string" value=" " />
Copy the code

to:
  1. <param name="map_file_path" type="string" value=" /home/yourname/Documents/livox_pcd_files" />
Copy the code

Or where ever you would like to store it.

Make sure you create the folder first and you have rights to write to it.

On my Jetson AGX I have to open the folder once when I start up the computer or else nothing will write to it. The reason being is its and external harddrive. On my other machines I do not have to open it first. As long as the folder exists it writes to it.

Strange it does not run offline. I record the point cloud using ROS on a raspberry pie. Then copy the bag file to another computer. I then launch lidar_mapping in one terminal and rosbag play the file in another. When done playing I close livox_mapping with control C and it saves the file.

I have successfully parsed the point cloud data in *.lvx format into PLY and PCD formats (expandable to various common formats you need). Contact me if necessary, email: www.fxw66697@gmail.com
