Dependences

• Eigen

       sudo apt install libeigen3-dev

• Optimization (own fork)

       git clone https://github.com/mergarsal/Optimization.git

• GNCSO

        git clone --recursive https://github.com/mergarsal/GNCSO.git 

• OpenGV

Build

git clone --recursive https://github.com/mergarsal/FastCertRelPose.git
cd GNCSO

mkdir build & cd build 

cmake .. 

make -jX

The compiled examples should be inside the bin directory. Run:

        ./bin/example_essential_matrix

Install

In build folder:

        sudo make install

We also provide the uninstall script:

        sudo make uninstall

How to use the library in your project

See the example in the folder example_install for the basic elements.

1. In your CMakeLists.txt, add the dependences:

        find_package(gncso REQUIRED)
        find_package(opengv REQUIRED)        
        find_package(Essential REQUIRED)

2. For your executable, add the library in

        target_link_libraries(XXX Essential opengv gncso)
