E57 Files not Imported to Reality Capture

Hi,

I am trying to import E57 files to Reality Capture but they are not being imported.
For Few scans, it shows a warning: Sampling Estimation Failed. Probably, the imported data is not a scan.
For Few scans, it shows that the files are imported, but none of them are visible in the project. Even the lsp’s are not created.

I captured the Lidar data and stored it in a ROSBag .db3 format. By using a python script, i have created a txt file which has X,Y,Z and intensity with whitespaces in between.

The Scans are clearly visible when imported onto CloudCompare and in MeshLab, but RC is not recognizing them.

Summary of obtaining E57s:

Robot Scan → Data Stored in ROSBag (.db3) ->Read data from python script while playing the ROSBag → Txt File → Import onto Cloud Compare, Export as E57.

Lidar Used: 4D Lidar L1.

Any Suggestion?
