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

---

Install

pip install genz-icp

If you also want to install all the dependencies, like Open3D/Polyscope for visualization (recommended):

pip install "genz-icp[all]"

Running the system

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.

Config

You can generate a default config genz_icp.yaml by typing:

genz_icp_dump_config

Now, you can modify the parameters and pass the file to --config when running genz_icp_pipeline as follows:

genz_icp_pipeline --config /path/to/genz_icp.yaml --visualize /path/to/data --topic /pointcloud_topic

Built-in pre-tuned configs (installed with pip)

Pre-tuned YAML files are packaged together with genz-icp, so you can use them by filename directly.

Available pre-tuned configs:

• corridor.yaml: Ground-Challenge dataset, Corridor1 and Corridor2 sequences (topic: /velodyne_points)
• exp07.yaml: Hilti-Oxford dataset, Exp07 sequence (topic: /hesai/pandar)
• kitti.yaml: KITTI odometry dataset (topic: /velodyne_points)
• long_corridor.yaml: SubT-MRS dataset, Long_Corridor sequence (topic: /velodyne_points)
• newer_college.yaml: Newer College dataset, 01_short_experiment, 02_long_experiment, 07_parklandmount sequences (topic: /os1_cloud_node/points)
• indoor.yaml: General indoor environments (topic set by user input)
• outdoor.yaml: General outdoor environments (topic set by user input)

Example:

genz_icp_pipeline --config long_corridor.yaml --visualize /path/to/data --topic /velodyne_points

You can still pass your own local YAML path:

genz_icp_pipeline --config /path/to/my_config.yaml --visualize /path/to/data --topic /pointcloud_topic

Install Python API (developer mode)

If you plan to modify the code, the main requirements are a modern C++ compiler and pip. In Ubuntu-based systems:

sudo apt install g++ python3-pip

Then clone and install editable mode:

git clone https://github.com/cocel-postech/genz-icp.git
cd genz-icp
python3 -m pip install -e ./python --no-build-isolation

Install Python API (expert mode)

If you want more control over the build, install CMake and dependencies explicitly:

sudo apt install build-essential libeigen3-dev libtbb-dev pybind11-dev ninja-build
