Integrating visual and inertial sensors has become a common practice in navigation due to the increase in computer power, in algorithms advancement and in sensor improvements. One of the problems yet to be solved is the Simultaneous Localisation And Mapping (SLAM). SLAM is a term used in the robotics community to describe the problem of mapping the environment... In this paper, the methodology is presented, differences with other SLAM solutions are pointed out, and numerical tests are provided and discussed.
