Patchwork++, an extension of Patchwork, is a fast, robust, and self-adaptive ground segmentation algorithm on 3D point cloud.

📂 What's in this repo

If you are familiar with ROS1, you can also visit here and try executing ROS1-based Patchwork++!

📦 Prerequisite packages

What we need are just minimal dependencies.

sudo apt-get install g++ build-essential libeigen3-dev python3-pip python3-dev cmake -y

⚙️ How to build & Run

Python

Pure installation

make pyinstall

Then, you can use Patchwork++ by import pypatchworkpp, which is super simple!

Installation to run demo

Only Open3D (> 0.17.0) is additionally installed for visualization purposes.

make pyinstall_with_demo

How to run Python demos is explained here.

C++

Pure installation

make cppinstall

Installation with demo

Only Open3D (> 0.17.0) is additionally installed for visualization purposes.

make cppinstall_with_demo

How to run the C++ demos is explained here.

ROS2

You should not need any extra dependency, just clone and build:

mkdir -p ~/ros2_ws/src
cd ~/ros2_ws/src
git clone https://github.com/url-kaist/patchwork-plusplus.git
cd ~/ros2_ws
colcon build --packages-select patchworkpp
source ./install/setup.bash

How to launch ROS2 nodes is explained here.
