This is a small python binding to the pointcloud library. Currently, the following parts of the API are wrapped (all methods operate on PointXYZ) point types
- I/O and integration; saving and loading PCD files
- segmentation
- SAC
- smoothing
- filtering
- registration (ICP, GICP, ICP_NL)
The code tries to follow the Point Cloud API, and also provides helper function for interacting with NumPy. For example (from tests/test.py)
import pcl
import numpy as np
p = pcl.PointCloud(np.array([[1, 2, 3], [3, 4, 5]], dtype=np.float32))
seg = p.make_segmenter()
seg.set_model_type(pcl.SACMODEL_PLANE)
seg.set_method_type(pcl.SAC_RANSAC)
indices, model = seg.segment()or, for smoothing
import pcl
p = pcl.load("C/table_scene_lms400.pcd")
fil = p.make_statistical_outlier_filter()
fil.set_mean_k (50)
fil.set_std_dev_mul_thresh (1.0)
fil.filter().to_file("inliers.pcd")Point clouds can be viewed as NumPy arrays, so modifying them is possible using all the familiar NumPy functionality:
import numpy as np
import pcl
p = pcl.PointCloud(10) # "empty" point cloud
a = np.asarray(p) # NumPy view on the cloud
a[:] = 0 # fill with zeros
print(p[3]) # prints (0.0, 0.0, 0.0)
a[:, 0] = 1 # set x coordinates to 1
print(p[3]) # prints (1.0, 0.0, 0.0)More samples can be found in the examples directory, and in the unit tests.

- Install PCL Module.
$ sudo apt-get update -y $ sudo apt-get install libpcl-dev -y Reference `here <https://packages.ubuntu.com/search?keywords=libpcl-dev>`_.PCL 1.8.x/1.9.x and Ubuntu16.04/18.04(build module)([CI Test Timeout])
Build Module
Reference here.
Case1. use homebrew(PCL 1.9.1 - 2018/12/25 current)
Install PCL Module.
$ brew tap homebrew/science
$ brew install pcl
Case1. use old homebrew(PCL 1.8.1 - 2017/11/13 current)
Check git log.
$ cd /usr/local/Library/Formula
$ git log ...
git checkout (target hash) pcl.rb
write after.
Warning:
Current Installer (2017/10/02) Not generated pcl-2d-1.8.pc file.(Issue #119)
Reference PointCloudLibrary Issue.
circumvent:
copy travis/pcl-2d-1.8.pc file to /usr/local/lib/pkgconfig folder.
This is the simpliest method on windows. The wheel contains the PCL binaries _ and thus you do not need to install the original PCL library.
- Go in the history on the appveyor page
- Click on the last successful revision (green) and click on the job corresponding to your python version
- Go in the artfacts section for that job and download the wheel (the file with extension whl)
- In the command line, move to your download folder and run the following command (replacing XXX by the right string)
pip install python_pcl-XXX.whlIf the method using the procompiled wheel does not work you can compile the binding from the source.
Case1. use PCL 1.6.0
Windows SDK 7.1

- install python-pcl with conda (solved)
conda create -n ipk # create a new conda env.
conda activate ipk # activate env.
conda update -n base -c defaults conda # update conda
conda config --add channels conda-forge # add conda-forge channels
conda install -c sirokujira python-pcl # pcl installation
conda install -c jithinpr2 gtk3 # Gtk+ Gui dependency
conda install -y ipython # install ipython
conda install -y jupyter # install jupyter
After that, run jupyter notebook or ipython shell to test pcl installation.

Point Cloud is a heavily templated API, and consequently mapping this into Python using Cython is challenging.
It is written in Cython, and implements enough hard bits of the API (from Cythons perspective, i.e the template/smart_ptr bits) to provide a foundation for someone wishing to carry on.
For deficiencies in this documentation, please consult the PCL API docs, and the PCL tutorials.
