    Parar eliminar éste vínculo hay que hacer dos pasos más...
    5 - Seleccionar ahora toda la tabla (en el word) y copiarla de nuevo [Ctrl + C]

    6 - Pegarla de nuevo en el documento word (en su posición definitiva) Manteniendo el formato de origen (M)
    Así queda (más o menos) la nueva tabla (sin vínculos) en word

    SLAMICP Library: Accelerating Obstacle Detection in Mobile Robot Navigation via Outlier Monitoring following ICP Localization, Sensors 2023, 23, 6089.

    This work proposes to speed up the obstacle detection process by directly monitoring outliers (discrepant points between the LIDAR scans and the full map) spotted after Iterative Closest Point (ICP) matching instead of spending time performing an isolated task to re-analyze the LIDAR scans to detect those discrepancies.

    This paper features the SLAMICP Library: a Free and Open Source library that we developped to implement ICP matching returning the outliers detected and other internal matching parameters during mobile robot navigation.

    Point Cloud application example of the SLAMICP Library
    Mobile robot following a planned trajectory: the blue dots depict the 2D map of the facility; the dotted cyan points depict the planned trajectory and the green arrow the final position and orientation that must be achieved by the mobile robot; the solid olive line depict the real trajectory followed by the mobile robot and the brown arrow depit ist current position and orientation; the red points are the outliers detected after ICP matching that (in this case) reveal one side of an obstacle placed in the corridor.
