Re: Unable to make use of context based features

Ok, I figured it out. This is how you structure the config file, # NAMES OF YOUR POINT CLOUDS cloud: PC1=railway_000033_rail.laz # Point cloud for training cloud: corepoints=railway_000033_rail_sub04.laz # CORE POINTS core_points: corepoints # Feature points cloud: CTX=railway_000033_rail.laz # SCAL...

Unable to make use of context based features

When I try to run the 3DMASC -> train classifier through CloudCompare (ver. 2.13.2), I fail when trying to include the context based features DZx and DHy. I have read the manual, but still cannot figure out how to correctly structure the config file. This is how it looks like at the moment, # NAMES ...

Re: Error when loading classifier

I have now tried to re-run the process from scratch, using several different point clouds, without being able to reproduce the error. So, this is resolved.

Thank you again for your help!

Re: Error when loading classifier

Ok, thank you very much. I really appreciate your help! Regarding this, Are you sure about your configuration? Could you clarify? Do you mean if I installed CC and its dependencies correctly, or do you mean the 3DMASC settings/configuration? Anyway, I will give it another try. Sounds like it would b...

Re: Error when loading classifier

I launched the training on the railway_000033.laz file at once, without using a subset as core_points. This is the initial parameter file, # NAMES OF YOUR POINT CLOUDS #cloud: PC1=railway_000033_rail.laz # Point cloud for training cloud: PC1= #cloud: corepoints=railway_000033_rail_sub04.laz # CORE P...

I used the following settings,

Max depth: 25
Max tree count: 100
Active var count: 0
Min sample count: 10

Scales: 0.5:0.5:2

Re: Error when loading classifier

Thank you for the reply!

I used the railway_000033.laz file.

The classifier.yaml file is large (8,53 GB (9 160 938 366 bytes)). I will try to find a way to share it.
Is the size of the .yaml file as expected?
