Distributed Pose Graph Optimization

Overview

DPGO

Introduction

This repository contains implementation of synchronous and asynchronous Distributed Pose Graph Optimization (DPGO). The algorithms are described in the following publications:

Building the C++ Library

Install dependencies.

sudo apt-get install build-essential cmake-gui libsuitesparse-dev

Inside the C++ directory, execute the following commands.

mkdir build
cd build
cmake ../
make

The built executables are located in directory build/bin. For a serialized demo of distributed PGO on one of the benchmark datasets, inside the build directory run:

./bin/multi-robot-example 5 ../data/smallGrid3D.g2o

Optionally, run the unit tests by,

./bin/testDPGO

ROS Support

A ROS wrapper of dpgo is provided: dpgo_ros. If you want to use dpgo with ROS, please follow instructions in the README.
