patchwork-plusplus-ros

This is ROS package of Patchwork++ (@ IROS'22), which is a fast and robust ground segmentation method.

If you are not familiar with ROS, please visit the original repository.

If you follow the repository, you can run Patchwork++ in Python and C++ easily.

📂 What's in this repository

• ROS based Patchwork source code (patchworkpp.hpp)
• Demo launch file (demo.launch) with sample rosbag file. You can execute Patchwork++ simply!

📦 Prerequisite packages

You may need to install ROS, PCL, Eigen, ...

⚙️ How to build Patchwork++

To build Patchwork++, you can follow below codes.

$ mkdir -p ~/ros2_ws/src
$ cd ~/ros2_ws
$ colcon build --packages-select patchworkpp --symlink-install

🏃 To run the demo codes

There is a demo which executes Patchwork++ with sample rosbag file. You can download a sample file with the following command.

download Kitti dataset for ros2 [kittiRos2link]: https://github.com/umtclskn/ros2_kitti_publishers/tree/main

Then, you can run demo as follows.

# Start Patchwork++
$ ros2 launch patchworkpp demo.launch
# Start the bag file
$ ros2 bag play kitti_00_sample.db3

📌 TODO List

• Update additional demo codes processing data with .bin file format
• Generalize point type in the source code
• Add visualization result of demo codes in readme
