Hum, those stripes look like the big coordinates were not handled properly and some accuracy has been lost... It may not help the classification process!

Hi there,

I read here and on the CC Github page (https://github.com/CloudCompare/CloudCompare/issues/520 and https://github.com/CloudCompare/CloudCompare/issues/749) that the qCanupo plugin is not (yet) Open Source.

Is the author somewhere in this forum? Is it possible to change the license of the qCanupo plugin to make it Open Source ? As CloudCompare and the canupo source code http://nicolas.brodu.net/code/canupo

I've another Canupo related question: do you think it's possible to classify different types of rock (limestone, granite or marl) from a 3D scene with a cliff, some vegetation and mass of fallen rocks ?

Thank you
daniel

Sorry for the delay (I was in vacations ;)).

I just asked Dimitri (the author) about making Canupo open-source.

And for the other question, I'm not the expert here, but I would say that if the scans resolution is high enough, there might be some chances to actually achieve that kind of result.

Hi,

I'm just a co-author of Canupo with N. Brodu, but it's money from projects I run that funded the implementation in Cloudcompare.
I've now asked Daniel to make qCanupo open source

As for your request, Canupo is a binary classifier using geometry. If the difference between limestome, marls etc... is only related to intensity or RGB information Canupo will not help. But for vegetation, it works really well on cliffs, especially as it is fully 3D (e.g., it does not presuppose that the ground is horizontal and the vegetation is above it). If you want to create 3 classes, you'll have to perform 2 successive classification operations.

Cheers

Dimitri

Thank you Daniel & Dimitri for your answers.

Make qCanupo Open Source is a very good news! I'm looking forward to see this plugin in the CloudCompare source project.

Daniel: do you have an idea when you'll be able to release the code?

Thank you !

Hi Everyone,

Done! qCANUPO is now open-source! A big thank to Dimitri ;)

It is now part of the official CC repository:
