CloudCompare forum

Hi,
I am trying to save a point cloud to a pcd file using cloudcompare command line, but I am having issues with the global shift. It doesn't seem to shift back to the original coordinates when saved. I have tried setting -GLOBAL_SHIFT AUTO but it still outputs the wrong coordinates. This is the command line I am using at the moment:

CloudCompare -SILENT -C_EXPORT_FMT PCD -o -GLOBAL_SHIFT AUTO /home/chris/Documents/ResearchArea.las -NO_TIMESTAMP -SAVE_CLOUDS

Using asc as output like this:

CloudCompare -SILENT -C_EXPORT_FMT ASC -o -GLOBAL_SHIFT AUTO /home/chris/Documents/ResearchArea.las -NO_TIMESTAMP -SAVE_CLOUDS

does give me the right coordinates. Any idea how I can fix this?

The current implementation of the PCD filter uses 32 bits floating point values to save coordinates in PCD files. Which means that you can't save large coordinates in such files.

I don't know if PCD files can handle 64 bits float values (I'm not the one who implemented this filter, and I don't know much about PCL).
