geo3dfeatures 0.4.0.post2

Description:

geo3dfeatures 0.4.0.post2

Extract geometry features from 3D point clouds
Content
The project contains the following folders:

geo3dfeatures contains source code
docs contains some mardown files for documentation purpose and
images
examples contains some Jupyter notebooks for describing data
tests; pytest is used to launch several tests from this folder

Additionally, running the code may generate extra subdirectories in a chosen
data repository (./data, by default).
How to install
This projects runs with Python3, every dependencies are managed
through poetry.
Installation from source
$ git clone ssh://[email protected]:10022/Oslandia-data/geo3dfeatures.git
$ cd geo3dfeatures
$ virtualenv -p /usr/bin/python3 venv
$ source venv/bin/activate
(venv)$ poetry install

Contribution
See CONTRIBUTING.md.
Run commands
In order to get the available program commands, consider the program help (geo3d -h):
usage: geo3d [-h] {info,sample,index,featurize,cluster,train,predict} ...

Geo3dfeatures framework for 3D semantic analysis

positional arguments:
{info,sample,index,featurize,cluster,train,predict}
info Describe an input .las file
sample Extract a sample of a .las file
index Index a point cloud file and serialize it
featurize Extract the geometric feature associated to 3D points
cluster Cluster a set of 3D points with a k-means algorithm
train Train a semantic segmentation model
predict Predict 3D point semantic class starting from a
trained model

optional arguments:
-h, --help show this help message and exit

Any further CLI documentation may be printed with geo3d <command> -h.
Documentation
Some documentation is available, that describes the set of considered geometric
features, the fixtures (i.e. dummy datasets) used for test purpose and a
practical pipeline use case:

Examples
The following example has been generated starting from
a CANUPO dataset (file scene.xyz, with 500k points, 50 neighbors and all the features):
