  3. 2. Visual-Inertial SLAM Using a Monocular Camera and Detailed Map Data

    University essay from Linköpings universitet/Reglerteknik

    Author : Viktor Ekström; Ludvig Berglund; [2023]
    Keywords : SLAM; localisation; monocular camera; GTSAM; factor graphs; iSAM2;

    Abstract : The most commonly used localisation methods, such as GPS, rely on external signals to generate an estimate of the location. There is a need of systems which are independent of external signals in order to increase the robustness of the localisation capabilities. READ MORE
