compare two revisions in a FARO Scene Project

Post by SAttaya »

Daniel,

Have you thought of comparing two revisions in a FARO Scene project?

You'd have to process the .LSproj (alternatively, for some, a workspace project?).
I specify the .lsproj file and the revision number instead of files to compare.
[Would have the advantage of comparing entire project to another entire
project (or maybe cluster, due to RAM limitations)].

Potentially there would only be one set of point clouds if the
only thing that changed between them was the transformations,
probably due to different registrations, but maybe nudging with
the manual manipulator or transformation properties change.
Regardless how the transformation is changed, you'd just reference
the registration. (It's possible the underlying point
clouds were modified as well as the transformation, and that
could be an option: use the point clouds that go with a specific
revision (more RAM) or just use the final/current point cloud
(which would use 1/2 (one-half) the RAM as you'd only need one copy
of the point cloud) with the select revision transformation. The
results would not be exactly the same, but the points deleted
would probably be noise and for the addition capacity and reduced
I/O time, it would be fine for evaluation purposes).

Saves the time to export the individual files out of scene and the time (and RAM)
to import them.

Just a thought for consideration down the road.
(I'm trying to do some process development and need to compare
different registration results
.)

Steve,

It *should* be possible to use the 'Save Copies of Scans' function in a revision. This will very quickly output the current status of the project to .FLS files. I say should, because I haven't actually tried to do this after loading an earlier revision. However, I know that some of the export functions aren't permitted in loaded revisions.

Hi Steve,

Sorry for the slow reaction, I somehow missed your post.

Do you mean that in a single Scene project you can have multiple revisions and you can choose the one you want to restore? If yes I'm not sure to have access to this information as the LS SDK is quite limited (there's a new and more advanced SDK but last time we tested it for the I/O plugin it wasn't 100% functional yet).

Scene projects do have multiple revisions which you can restore to at any time. You can restore to exactly the way a project was at any time you manually saved. After that, it stands to logic that you can save a copy of scans and have that revision registered exactly as it was shown in Scene. Remember though that it only creates a new revision when you save. Not sure if it does the same for auto saves.

To check for your revisions go to file > scan project > project history
