(May 19, 2026) pip installation is now live:
pip install genz-icp

GenZ-ICP is a Generalizable and Degeneracy-Robust LiDAR Odometry Using an Adaptive Weighting

Install

pip install genz-icp

Next, follow the instructions on how to run the system by typing:

genz_icp_pipeline --help

This should print a help message with supported dataloaders and options.

For advanced instructions on the Python package please see this README

ROS support

ROS 1

Build

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
git clone https://github.com/cocel-postech/genz-icp.git
cd ..
catkin build genz_icp --cmake-args -DCMAKE_BUILD_TYPE=Release
source ~/catkin_ws/devel/setup.bash

Run with pre-tuned config

roslaunch genz_icp odometry.launch topic:=<topic_name> config_file:=<config_file_name>.yaml
rosbag play <rosbag_file_name>.bag

Run with only topic

roslaunch genz_icp odometry.launch topic:=<topic_name>
rosbag play <rosbag_file_name>.bag

Examples and download links for demo datasets are available in ros/README.md.

Parameter tuning guide: ros/config/parameter_tuning_guide.md

ROS 2

Build

mkdir -p ~/colcon_ws/src
cd ~/colcon_ws/src
git clone https://github.com/cocel-postech/genz-icp.git
cd ..
colcon build --packages-select genz_icp --cmake-args -DCMAKE_BUILD_TYPE=Release --symlink-install
source ~/colcon_ws/install/setup.bash

Run with pre-tuned config

ros2 launch genz_icp odometry.launch.py topic:=<topic_name> config_file:=<config_file_name>.yaml
ros2 bag play <rosbag_file_name>.db3

Run with only topic

ros2 launch genz_icp odometry.launch.py topic:=<topic_name>
ros2 bag play <rosbag_file_name>.db3
