libRSF - A Robust Sensor Fusion Library

The libRSF is an open source C++ library that provides the basic components for robust sensor fusion. It can be used to describe an estimation problem as a factor graph and solves it with least squares, powered by the Ceres Solver. More information can be found under libRSF - A Robust Sensor Fusion Library.

Main features are:

• A sliding window filter for online applications, including marginalization.
• A set of predefined cost functions for various localization problems.
• Several robust error models for non-Gaussian problems, including self-tuning Gaussian mixtures.

Build and Test Status

Platform	Status
Ubuntu 20.04
Ubuntu 18.04

Installation

The libRSF is a CMake project that requires the installation of several dependencies. For convenience, we provide a simple bash script that installs required packages. It is tested only for Ubuntu 18.04/20.04:

 git clone https://github.com/TUC-ProAut/libRSF.git
cd libRSF
bash InstallDependencies.bash

Alternatively, you can install them by your own:

• CMake (>= 3.5)

  sudo apt-get install cmake

• Eigen (>= 3.3.5)

  Only for Ubuntu 18.04, you have to install a current version of Eigen locally.

  mkdir -p externals/install
  git submodule update --init externals/eigen
  cd externals/eigen
  mkdir -p build &&cd build
  cmake -DCMAKE_INSTALL_PREFIX=../../install/ ..
  make install
  cd ../../..

  For Ubuntu >= 20.04 you can install Eigen straight-forward.

  sudo apt-get install libeigen3-dev

• Ceres (>= 2.0) and its dependencies

  sudo apt-get install libgoogle-glog-dev
  sudo apt-get libgflags-dev
  sudo apt-get install libatlas-base-dev
  sudo apt-get install libsuitesparse-dev
  mkdir -p externals/install git submodule update --init externals/ceres-solver
  cd externals/ceres-solver
  mkdir build &&cd build
  cmake -DEigen3_DIR=../install/share/eigen3/cmake -DCMAKE_INSTALL_PREFIX=../../install/ ..
  make all -j$(getconf _NPROCESSORS_ONLN)
  make install
  cd ../..

• yaml-cpp

  sudo apt-get install libyaml-cpp-dev

• GeographicLib

  sudo apt-get install libgeographic-dev

The library and its applications can be build following this instructions:

 git clone https://github.com/TUC-ProAut/libRSF.git
cd libRSF
mkdir build &&cd build
cmake ..
make all -j$(getconf _NPROCESSORS_ONLN)

You can install the libRSF using:

 make install

And remove it using:

 make uninstall

Usage

After building the library, some applications are provided which correspond directly to a publication. The following pages give you an overview, how to use them or how to build a custom application using the libRSF:

1. How to use the robust GNSS localization from our ICRA 2019 or IV 2019 paper?

2. How to use the robust Gaussian mixture models from our RA-L 2021 Paper?

3. How to build your own application on top of the libRSF? (under construction)
