g2o: A General Framework for Graph Optimization

Last update: Dec 30, 2022

Overview

g2o - General Graph Optimization

Linux: Windows:

g2o is an open-source C++ framework for optimizing graph-based nonlinear error functions. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code. The current implementation provides solutions to several variants of SLAM and BA.

A wide range of problems in robotics as well as in computer-vision involve the minimization of a non-linear error function that can be represented as a graph. Typical instances are simultaneous localization and mapping (SLAM) or bundle adjustment (BA). The overall goal in these problems is to find the configuration of parameters or state variables that maximally explain a set of measurements affected by Gaussian noise. g2o is an open-source C++ framework for such nonlinear least squares problems. g2o has been designed to be easily extensible to a wide range of problems and a new problem typically can be specified in a few lines of code. The current implementation provides solutions to several variants of SLAM and BA. g2o offers a performance comparable to implementations of state-of-the-art approaches for the specific problems (02/2011).

Requirements

C++14 compiler (CI pipeline runs with gcc, clang and MSVC)
cmake http://www.cmake.org
Eigen3 http://eigen.tuxfamily.org

On Ubuntu / Debian these dependencies are resolved by installing the following packages.

cmake
libeigen3-dev

Optional requirements

suitesparse http://faculty.cse.tamu.edu/davis/suitesparse.html
Qt5 http://qt-project.org
libQGLViewer http://www.libqglviewer.com

On Ubuntu / Debian these dependencies are resolved by installing the following packages.

libsuitesparse-dev
qtdeclarative5-dev
qt5-qmake
libqglviewer-dev-qt5

Mac OS X

If using Homebrew, then

brew install brewsci/science/g2o

will install g2o together with its required dependencies. In this case no manual compilation is necessary.

Windows

If using vcpkg, then

scripts\install-deps-windows.bat

will build and install the required dependencies. The location of vcpkg and required triplet are determined by the environment variables VCPKG_ROOT_DIR and VCPKG_DEFAULT_TRIPLET.

Compilation

Our primary development platform is Linux. Experimental support for Mac OS X, Android and Windows (MinGW or MSVC). We recommend a so-called out of source build which can be achieved by the following command sequence.

mkdir build
cd build
cmake ../
make

The binaries will be placed in bin and the libraries in lib which are both located in the top-level folder.

On Windows with vcpkg the following two commands will generate build scripts for Visual Studio 2017 MSVC 14 tool set:

mkdir build
cd build
cmake -G "Visual Studio 14 2017 Win64" -DG2O_BUILD_APPS=ON -DG2O_BUILD_EXAMPLES=ON -DVCPKG_TARGET_TRIPLET="%VCPKG_DEFAULT_TRIPLET%" -DCMAKE_TOOLCHAIN_FILE="%VCPKG_ROOT_DIR%\scripts\buildsystems\vcpkg.cmake" ..

If you are compiling on Windows and you are for some reasons not using vcpkg please download Eigen3 and extract it. Within cmake-gui set the variable G2O_EIGEN3_INCLUDE to that directory.

Cross-Compiling for Android

mkdir build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../script/android.toolchain.cmake -DANDROID_NDK=<YOUR_PATH_TO_ANDROID_NDK_r10d+> -DCMAKE_BUILD_TYPE=Release -DANDROID_ABI="armeabi-v7a with NEON" -DEIGEN3_INCLUDE_DIR="<YOUR_PATH_TO_EIGEN>" -DEIGEN3_VERSION_OK=ON .. && cmake --build .

Acknowledgments

We thank the following contributors for providing patches:

Simon J. Julier: patches to achieve compatibility with Mac OS X and others.
Michael A. Eriksen for submitting patches to compile with MSVC.
Mark Pupilli for submitting patches to compile with MSVC.

Memory Corruption and Segfault on basic example

Hi everybody,

first of all thanks for this great piece of software! I have used g2o before, but I get segfault and memory corruption errors with a fairly new version of g2o. Note that compiling works like a charm, no errors there. I have also used g2o before with an older version (latest tag). Here are my details:

OS: Ubuntu 16.04 G2O Revision: 653c9eedc51f73394451cd8f55463c962b4092ab GCC: gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609 CMake: cmake version 3.5.1

I have created a very simple example which crashes in my setup all the time.

#include <g2o/core/block_solver.h>
#include <g2o/core/optimization_algorithm_levenberg.h>
#include <g2o/solvers/csparse/linear_solver_csparse.h>
#include <g2o/types/slam3d/edge_se3.h>
#include <g2o/types/slam3d/vertex_se3.h>

typedef g2o::LinearSolverCSparse<g2o::BlockSolverX::PoseMatrixType> SlamLinearSolver;

int main(int argc, char **argv)
{
    g2o::SparseOptimizer optimizer;


    auto linearSolver = g2o::make_unique<SlamLinearSolver>();
    linearSolver->setBlockOrdering(false);

    auto blockSolver =
        g2o::make_unique<g2o::BlockSolverX>(std::move(linearSolver));

    g2o::OptimizationAlgorithm *algorithm =
        new g2o::OptimizationAlgorithmLevenberg(std::move(blockSolver));

    optimizer.setVerbose(true);
    optimizer.setAlgorithm(algorithm);

    g2o::VertexSE3 *v = new g2o::VertexSE3();
    v->setId(0);
    v->setEstimate(g2o::Isometry3::Identity());
    v->setFixed(false);
    optimizer.addVertex(v);

    v = new g2o::VertexSE3();
    v->setId(1);
    v->setEstimate(g2o::Isometry3::Identity());
    v->setFixed(false);
    optimizer.addVertex(v);

    g2o::EdgeSE3 *e = new g2o::EdgeSE3();
    e->setInformation(g2o::EdgeSE3::InformationType::Identity());
    e->setMeasurement(g2o::Isometry3::Identity());
    e->vertices()[0] = optimizer.vertex(0);
    e->vertices()[1] = optimizer.vertex(1);
    optimizer.addEdge(e);

    optimizer.initializeOptimization();
    optimizer.optimize(100);

    return 0;
}

The crash creates direct command line output stating a memory corruption as follows:

cs.h no such file or directory

I went through the issue mentioned here https://github.com/RainerKuemmerle/g2o/issues/23 But I am still facing the error even after making the suggested changes. I am downloading the g2o package from github as I have mentioned the link to download the package in my Makefile. I tried making the suggested changes to the files that are downloaded but I get the error again and again.

Any help on it will be appreciated.

Thanks

C++11 support

C++11 completely changes the way that random numbers are generated, and deprecates things such as tr1.

I was thinking of setting up a separate branch to look at the C++11 issues and to see if it works okay on various platforms. (In particular, the Mavericks clang build on a Mac is currently broken as a result.)

Any concerns?

compilation error in ceres/jet.h

Hello,

I am trying to build g2o. I got the following error.

/home/anindya/g2o/EXTERNAL/ceres/jet.h:980:8: error: ‘ScalarBinaryOpTraits’ is not a class template struct ScalarBinaryOpTraits<ceres::Jet<T, N>, T, BinaryOp> { ^~~~~~~~~~~~~~~~~~~~ /home/anindya/g2o/EXTERNAL/ceres/jet.h:984:58: error: type/value mismatch at argument 3 in template parameter list for ‘template<class BinaryOp, class T, int N> struct Eigen::ScalarBinaryOpTraits’ struct ScalarBinaryOpTraits<T, ceres::Jet<T, N>, BinaryOp> { ^ /home/anindya/g2o/EXTERNAL/ceres/jet.h:984:58: note: expected a constant of type ‘int’, got ‘BinaryOp’

Please let me know if this is a bug or if I am missing something. I have all the dependencies installed in my PC though.

thank you for your response.

regards, Anindya

How to put in constraints like GPS (or any other global positioning) for slam

I am currently working on an outdoor slam solution with pose graphs and the results are good in general but unfortunately the graph drifts too much for building a complete consistent map.

The graph is build up by connecting the poses either with odometry or scan matching measurements (if available). The robot has an gps but now i am not sure how to put constraints with this new measurement source.

I thought about connecting each pose with the fixed one (the first) and add the computed distance of the gps readings? Therefore i would not need to transform the gps fix to the map frame.

Is there any example or advise how someone can feed global positions (with uncertainty) into such an pose graph?

thanks

Segmentation fault optimizing with EdgeSE3PointXYZ

Hello everyone.

I receive the following message from gdb when I try to call g2o::SparseOptimizer::optimize () in a graph that has 2 vertex SE3, which one is fixed, and one vertex PointXYZ ( representing Landmark ), 2 EdgeSE3 connecting the 2 vertex SE3 and a EdgeSE3PointXYZ connecting a vertex SE3 to a vertex PointXYZ. The solver is "lm_var_cholmod"

0x00007ffff7c3d042 in double __vector(2) Eigen::internal::pload<double __vector(2)>
(Eigen::internal::unpacket_traits<double__vector(2)>::type const*) () from /usr/local/lib/libg2o_core.so

If I use the solver "lm_fix6_3_cholmod" it throws another error:

graph_optimization_node: /usr/include/Eigen/src/Core/PlainObjectBase.h:281: void
Eigen::PlainObjectBase<Derived>::resize(Eigen::Index, Eigen::Index) [with Derived = 
Eigen::Matrix<double, 6, 6, 0>; Eigen::Index = long int]: Assertion `(!(RowsAtCompileTime!=Dynamic) ||

(!(ColsAtCompileTime==Dynamic && MaxColsAtCompileTime!=Dynamic) || (cols<=MaxColsAtCompileTime)) && rows>=0 &&
cols>=0 && "Invalid sizes when resizing a matrix or array."' failed.

It works fine with only VertexSE3 and EdgeSE3. It is launched in Ubuntu 20.04, with the last g2o version and Eigen versrion 3.3.7. Has anyone any idea how to solve this? Maybe with some compilation flag.

Thank you in advance for your attention.

Are there any multiple edge tutorial? a multiple edge use error?
Hi, I have a new optimization problem. I think I need a multiple edge struct which link three vertex to optimize. Specifically, 1st and 2nd vertices are g2o::VertexSE3. 3rd vertex is a real number, so I think g2o::BaseVertex<1, double> is good. Meanwhile, I have some prior terms and I think I should use g2o::BaseUnaryEdge<1, double, MyRealNumberVertexType>.

In conclusion, I inherit 3 class. Respectively,
class MyRealNumberVertexType : public g2o::BaseVertex<1, double> To represent a real number variable.

class MyPriorEdge : public g2o::BaseUnaryEdge<1, double, MyRealNumberVertexType > As a weight to link MyRealNumberVertexType

class MyMultiEdge: public g2o::BaseMultiEdge<6, Eigen::Isometry3d> To link three vertices, two g2o::VertexSE3 and one MyRealNumberVertexType. By the way, this edge's measurement is a rigid transformation in 3 dimension world.

When I try optimize() after initializeOptimization(). I get a assert crash

Assertion failed: (!(RowsAtCompileTime!=Dynamic) || (nbRows==RowsAtCompileTime)) && (!(ColsAtCompileTime!=Dynamic) || (nbCols==ColsAtCompileTime)) && (!(RowsAtCompileTime==Dynamic && MaxRowsAtCompileTime!=Dynamic) || (nbRows<=MaxRowsAtCompileTime)) && (!(ColsAtCompileTime==Dynamic && MaxColsAtCompileTime!=Dynamic) || (nbCols<=MaxColsAtCompileTime)) && nbRows>=0 && nbCols>=0 && "Invalid sizes when resizing a matrix or array.", file eigen\eigen3\eigen\src\core\plainobjectbase.h, line 241

After debugging, I find the problem comes from

//in g2o/core/sparse_block_matrix.hpp line 101 _block=new typename SparseBlockMatrix<MatrixType>::SparseMatrixBlock(rb,cb);

The assert is triggered because rb=1, cb=1, but MatrixType is Eigen::Matrix<double,6,6,0,6,6> when program is running. That is it try create a SparseMatrixBlock which col=1 and row =1, while MatrixType is 6x6 matrix.

My question is why the template MatrixType is not change to Eigen::Matrix<double,1,1,0,1,1>? Not only do I have g2o::VertexSE3 vertex, but I also have real number vertex<1, double>.

Where is my wrong?

Any help would be appreciated.

Configuring with `FetchContent`

I'm trying to configure a simple test project with g2o using FetchContent like so:

cmake_minimum_required(VERSION 3.24)
project(testlib)

add_library(testlib SHARED library.cpp)
target_compile_features(testlib PUBLIC cxx_std_14)

include(FetchContent)
FetchContent_Declare(
        Eigen3
        GIT_REPOSITORY https://gitlab.com/libeigen/eigen.git
        GIT_TAG 3.4.0
        OVERRIDE_FIND_PACKAGE
)
FetchContent_Declare(
        g2o
        GIT_REPOSITORY https://github.com/RainerKuemmerle/g2o.git
        GIT_TAG origin/master
)
FetchContent_MakeAvailable(g2o)

target_link_libraries(testlib g2o)

This doesn't work: configuration finishes without errors (although there are warnings "BLA_VENDOR has been set to All but blas libraries could not be found or check of symbols failed") and I see g2o's CMake output, but during build I get /usr/bin/ld: cannot find -lg2o: No such file or directory. Same happens if I do target_link_libraries(testlib g2o_core) instead.

I also tried to use find_package for g2o:

FetchContent_Declare(
        g2o
        GIT_REPOSITORY https://github.com/RainerKuemmerle/g2o.git
        GIT_TAG origin/master
        OVERRIDE_FIND_PACKAGE
)

find_package(g2o REQUIRED)

target_link_libraries(testlib g2o)

But this gives the same result (also tried with target_link_libraries(testlib g2o_core) instead).

Is it possible to configure g2o with FetchProject?

failed to add vertex?

Hello,

I tried using a simple example to optimize poses. I have a class encapsulates several g2o items to do this, and all of pointers of them are initialized in the constructor, see


class Pose{

private:
	g2o::BlockSolver_6_3 * mog2oBS63;  // Solver type for pose matrix type.
	g2o::LinearSolverCSparse<g2o::BlockSolver_6_3::PoseMatrixType> * mog2oLSCSparse; // Linear solver.
	g2o::OptimizationAlgorithmLevenberg * mog2oOALeven;  // Levenberg optimizer.
	g2o::SparseOptimizer mog2oSOpt;
};

Pose::Pose(){
	// Allocating memory for g2o things.
	mog2oLSCSparse = new g2o::LinearSolverCSparse<g2o::BlockSolver_6_3::PoseMatrixType>();  // Linear solver initialization.
	mog2oLSCSparse->setBlockOrdering(false);
	mog2oBS63 = new g2o::BlockSolver_6_3(mog2oLSCSparse);  // Block solver ```
initialization.
	mog2oOALeven = new g2o::OptimizationAlgorithmLevenberg(mog2oBS63); // Optimizer initialization.
	mog2oSOpt.setAlgorithm(mog2oOALeven);  // Set algorithm for optimizer.
	mog2oSOpt.setVerbose(false);
}

In main(), an object of Pose is declared and then a member function Run() of Pose is called to get everything working. In Run(), I tried to add vertices into mog2oSOpt but failed to do that and don't know why. Here is a part of the code in Run()

Pose::Run(){
	g2o::VertexSE3 * pg2oVSE3 = new g2o::VertexSE3();
	pg2oVSE3->setId(0);
	pg2oVSE3->setEstimate(Eigen::Isometry3d::Identity());
	pg2oVSE3->setFixed(true);
	if (mog2oSOpt.addVertex(pg2oVSE3))
	{
		std::cout << "- vertex added: " << mog2oSOpt.vertices().size() << std::endl;
	}
	else
		std::cerr << "- vertex adding failed!" << std::endl;
}

The output is simply bizarre, see

vertex added: 6888592

Seg fault and infinite loop in computeEntry() while computing marginal covariance

Hallo, I am using the g2o for 3d pose graph optimization under the ros kinetic environment. For some usecases, we need the information about the uncertainty of 3d pose. So I tried to compute the marginal covariance. However sometimes the segmentation fault and infinite loop happens.

Following is the gdb backtrace for the case of infinite loop:
