CloudCompare forum

Hi,

I have to have access to the unfiltered scans of a Faro Focus 3D. I have 27 projects, with 5 scans per project. I am able to this in Faro Scene, which is very tedious. More over, you can't let Scene work by itself since the default filtered is deactivated during the processing, and you have to accept by clicking in a window upon the loading/processing of each scan. In other words, very long process,that cannot be automated.

I would thus like to use the command line operation of CloudCompare. The workflow would thus be:
- load the original, unprocessed .fls file (with the -O {filename} command line option). However, I would like to know if the Faro default filter (in Scene, Tools/Options/Default filter box checked) is applied. If it is, is there a possibility of not passing through the default filter when loading in CC?
- transform the data using the registration information obtained from Scene registration process ? (with the -APPLY_TRANS {filename} option)
- export in .xyz file (with the -C_EXPORT_FMT {format} option)

The questions are thus:
- is it possible to import a .fls file without the default filter ?
- and by chance, does anyone know if one can export the registration information in Faro Scene 6.2 to build the transformation matrix ?

Thanks !

Robert

What is the default 'filter' in Scene (I don't know how Scene works :D). Is it a kind of clipping box? If yes I assume CloudCompare will ignore it (or at least we don't have access to this information via the Faro LS SDK).

If you simply load the file in CloudCompare, do you see this 'filter' applied? The command line will actually behave exactly as the standard version.

All the other options are technically possible, assuming you can save each transformation as a separate text file...

Daniel,

I remember a related question came up a few years ago.

Perhaps the newer Faro units are now saving their data with RGB values for each point, however, the older ones use the panoramic images to apply the color as some type of mapping in Faro's software after the laser data is captured

So the raw scan, if I recall does not contain RGB values, and the Faro plugin for CloudCompare at the time did not support the image mapped color ... has this changed?

Thanks Daniel. I'll look into in the next few days.
