Panoptic Mapping

This package contains panoptic_mapping, a general framework for semantic volumetric mapping. We provide, among other, a submap-based approach that leverages panoptic scene understanding towards adaptive spatio-temporally consistent volumetric mapping, as well as regular, monolithic semantic mapping.

combined

Multi-resolution 3D Reconstruction, active and inactive panoptic submaps for temporal consistency, online change detection, and more.

Installation

Installation instructions for Linux. The repository was developed and tested on Ubuntu 18.04 with ROS melodic and Ubuntu 20.04 with ROS noetic.

Ubuntu 18.04 + ROS Melodic.

Prerequisites

  1. If not already done so, install ROS (Desktop-Full is recommended).

  2. If not already done so, create a catkin workspace with catkin tools:

sudo apt-get install python-catkin-tools  
mkdir -p ~/catkin_ws/src
cd ~/catkin_ws
catkin init
catkin config --extend /opt/ros/melodic
catkin config --cmake-args -DCMAKE_BUILD_TYPE=RelWithDebInfo
catkin config --merge-devel

Installation

  1. Install system dependencies:
sudo apt-get install python-wstool python-catkin-tools autoconf libtool git  
  1. Move to your catkin workspace:
cd ~/catkin_ws/src
  1. Download repo using SSH or HTTPS:
git clone git@github.com:ethz-asl/panoptic_mapping.git  # SSH
git clone https://github.com/ethz-asl/panoptic_mapping.git  # HTTPS
  1. Download and install package dependencies using ros install:
  • If you created a new workspace.
wstool init . ./panoptic_mapping/panoptic_mapping_ssh.rosinstall    # SSH
wstool init . ./panoptic_mapping/panoptic_mapping_https.rosinstall  # HTTPS
wstool update
  • If you use an existing workspace. Notice that some dependencies require specific branches that will be checked out.
wstool merge -t . ./panoptic_mapping/panoptic_mapping.rosinstall
wstool update
  1. Compile and source:
catkin build panoptic_mapping_utils
source ../devel/setup.bash

Ubuntu 20.04 + ROS Noetic.

Prerequisites

Datasets

The datasets described in the paper and used for the demo can be downloaded from the ASL Datasets.

A utility script is provided to directly download the flat data:

roscd panoptic_mapping_utils
export FLAT_DATA_DIR="/home/$USER/Documents"  # Or whichever path you prefer.
chmod +x panoptic_mapping_utils/scripts/download_flat_dataset.sh
./panoptic_mapping_utils/scripts/download_flat_dataset.sh

Additional data to run the mapper on the 3RScan dataset will follow.

Examples

Running the Panoptic Mapper

This example explains how to run the Panoptic Multi-TSDF mapper on the flat dataset.

  1. First, download the flat dataset:

    export FLAT_DATA_DIR="/home/$USER/Documents"  # Or whichever path you prefer.
    chmod +x panoptic_mapping_utils/scripts/download_flat_dataset.sh
    ./panoptic_mapping_utils/scripts/download_flat_dataset.sh
    
  2. Replace the data base_path in launch/run.launch (L10) and file_name in config/mapper/flat_groundtruth.yaml (L15) to the downloaded path.

  3. Run the mapper:

    roslaunch panoptic_mapping_ros run.launch
    
  4. You should now see the map being incrementally built:

  5. After the map finished building, you can save the map:

    rosservice call /panoptic_mapper/save_map "file_path: '/path/to/run1.panmap'" 
    
  6. Terminate the mapper pressing Ctrl+C. You can continue the experiment on run2 of the flat dataset by changing the base_path-ending in launch/run.launch (L10) to run2, and load_map and load_path in launch/run.launch (L26-27) to true and /path/to/run1.panmap, respectively. Optionally, you can also change the color_mode in config/mapper/flat_groundtruth.yaml (L118) to change to better highlight the change detection at work.

    roslaunch panoptic_mapping_ros run.launch
    
  7. You should now see the map being updated based on the first run:

Monolithic Semantic Mapping

Panoptic Mapping supports also the monolithic use case. This example explains how to run the Panoptic Single-TSDF mapper on the flat dataset.

  1. If not already done so, download the flat dataset:

    export FLAT_DATA_DIR="/home/$USER/Documents"  # Or whichever path you prefer.
    chmod +x panoptic_mapping_utils/scripts/download_flat_dataset.sh
    ./panoptic_mapping_utils/scripts/download_flat_dataset.sh
    
  2. Replace the data base_path in launch/run.launch (L10) and file_name in config/mapper/single_tsdf.yaml (L15) to the downloaded path.

  3. To use the single-TSDF mapper and real segmentation predictions, set use_detectron in launch/run.launch (L6) to true and config in launch/run.launch (L22) to 'single_tsdf'.

  4. Run the mapper:

    roslaunch panoptic_mapping_ros run.launch
    
  5. You should now see the map being incrementally built.

  6. Varying visualization modes are supported, the classes (default) will color the mesh according to the predicted semantic class. Other modes, such as classification will show the confidence of the aggregated predictions.

Predicted classes (left) and corresponding fusion confidence (right, low to high in red to green).

Running the RIO Dataset

This example will follow shortly.
