DHP-Mapping: A Dense Panoptic Mapping System with Hierarchical World Representation and Label Optimization Techniques

🔔 News

🎊 We plan to integrate Grounded-Segment-Anything, Yolo-World, and OWLv2 into this mapping pipeline, for online open-world semantic-mapping. Additionally, we will support Habitat-Lab to advance developments in embodied-AI. Stay tuned for our upcoming feature releases and don’t forget to give us a star!

🔥 27/12/2024 Release experiment configs and launch files.

🔥 26/11/2024 Release main algorithms!

🎈 Getting Started

Step1: Dataset and Pre-process

SemanticKITTI: Prepare the dataset to desired format, following dataset.

flat: Download the dataset from the ASL Datasets.

Step2 Workspace setup

sudo apt-get install python3-pip python3-wstool
mkdir -p DHP_ws/src
cd DHP_ws/src
git clone git@github.com:hutslib/DHP-mapping.git
wstool init . ./DHP-mapping/panoptic_mapping_ssh.rosinstall    # SSH
cd ..
catkin init
catkin config --extend /opt/ros/noetic
catkin config --cmake-args -DCMAKE_BUILD_TYPE=RelWithDebInfo
catkin config --merge-devel
catkin build panoptic_mapping_utils
source ../devel/setup.zsh

Step3 Modify config and launch file to run an experiment

The launch files are located in: panoptic_mapping_ros/launch/iros_exp

The config files are located in: panoptic_mapping_ros/config/mapper/iros_exp

Key Modifications:

• Update base_path and config in the launch file.
• Note: For long sequences in SemanticKITTI, adjust max_frames in the launch file to limit the number of frames based on your device's memory.
• Update the following in the config file:
  • save_map_path_when_finished
  • label_info_print_path
  • save_mesh_folder_path
  • submap_info_path
  • Tr
  • P2
  • labels: file_name
  • visualization: colormap_print_path
• Note: The Tr and P2 parameters should be modified based on the extrinsics calculated in the data preprocess step.

# run the experiment
roslaunch panoptic_mapping_ros iros_exp_kitti_detectron_07.launch

To Do

The code is under cleaning and will be released gradually.

• Initial repo & paper
• Dataset process & player & visualization
• Main algorithms code
• Config and launch files
• Visualization and other tools
• Improve docs
• Feature imporve: integrate open-world segmentation/detection algorithms
• Feature improve: supporting Habitat-Lab
