### 3.4 PCD file save
|
||||
|
||||
Set ``` pcd_save_enable ``` in launchfile to ``` 1 ```, every frame will be saved as an independent .PCD file in ``` FAST_LIO/PCD/ ``` directory.
|
||||
Set ``` pcd_save_enable ``` in launchfile to ``` 1 ```. All the scans (in global frame) will be accumulated and saved to the file ``` FAST_LIO/PCD/scans.pcd ``` after the FAST-LIO is terminated.
