CloudCompare forum

Hello,

I have been looking around and can't find a clear answer regarding this after looking through the RANSAC article (http://citeseerx.ist.psu.edu/viewdoc/do ... 1&type=pdf), what units does the algorithm measure height and radius of cylinders in? Is it meters? Apologies if I missed it.

Thank you,
Angela

For me it's the same units as the cloud. They have to be consistent.

And CC does not manage units, it reads the points (coordinates) as they are stored in the file. Almost no file format gives this information.

Great plugin, thank you!

After running RANSAC, how can you get plan info to transform the point cloud and align with X, Y, or Z plane?

There's no simple way to do that right now. You can just right click on a plane and ask CC to orient the camera so that it's facing the plane. Then the corresponding matrix is displayed in the Console (F8). You can then copy this matrix and paste it in the 'Apply transformation' tool... But that's limited to this particular case...

It worked! Thank you. Now on to cleaning up the offground data
