This repository contains a fork of OpenGV

Author: Steffen Urban (urbste at googlemail.com).

This fork contains three additional algorithms

MLPnP - a central absolute pose solver
a central relativ orientation solver (needs >= 6 pts) for small baselines, based on the ideas of MLPnP
and the multi-camera motion algorithm by Jonathan Ventura code

I could not compile latter on Windows, but on Linux it should compile fine. This is due to the the file approx_relpose_generalized_fast_computeA.cpp which the Microsoft compilter won't compile. If you like to compile this algorithm in Linux just uncomment the lines in this file.

For examples on how to use MLPnP and the relativ pose algorithm have a look at the Matlab scripts. Also have a look in the MLPnP repositories MLPnP,MLPnP_toolbox that contain Matlab implementations.

Results for MLPnP

These results can be reproduced by running benchmark_absolute_pose_cov.m
