14/03/2024 - Dia del número π = 3,141592653... y 31 trillones de decimales más !
Es la fecha en notación inglesa de mes-día que representa el número:
03-14
Se supone que si se organiza alguna fiesta de celebración debería empezar a las
16 h
O... si se quiere ser más preciso... a las
15:56 h
El minuto 56 se obtiene redondeando la conversión en fracción de hora de 92653, es decir 60 min * 0,92653 = 55,59 min o
55 min 35 s

21/12/2023 - New version (5.1) of the SLAMICP-Library
This
new version 5.1 of the
SLAMICP-Library optimizes the "point_to_plane"
ICP matching by avoiding to compute the normals of the reference map in each iteration.
There is also a specific function to compute the normals (red arrows) of a point cloud (blue points).

01/08/2023 - New Scientific paper published by the Laboratory
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.

En cas de que durant l'arrencada o al crear un fitxer nou
Windows 11 tardi més del normal es pot fer servir SFC (System File Checker -
comprovador i reparador dels arxius del sistema):
1. Obrir un
CMD (consola o finestra de comandes) com administrador
2. Executar el
SFC, teclejant a la consola:
sfc /scannow
3. Esperar a que el procés de comprovació acabi
