  1. 1. Performance metrics and velocity influence for point cloud registration in autonomous vehicles

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Óscar Poveda Ruiz; [2023]
    Keywords : autonomous vehicle; localization; registration; metrics; error; classification; estimation; autonomt fordon; lokalisering; registrering; mätvärden; fel; klassificering; uppskattning;

    Abstract : Autonomous vehicles are currently under study and one of the critical parts is the localization of the vehicle in the environment. Different localization methods have been studied over the years, such as the GPS sensor, commonly fused with other sensors such as the IMU. READ MORE

  3. 2. Robust light source detection for AUV docking

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Joar Edlund; [2023]
    Keywords : Autonomous Underwater Vehicle; Docking; Detection; Poseestimation; Visual Navigation; Autonoma Undervattensfordon; Dockning; Detektering; Positionsestimering; Visuell Navigation;

    Abstract : For Autonomous Underwater Vehicles (AUVs) to be able to conduct longterm surveys, the ability to return to a docking station for maintenance and recharging is crucial. A dynamic docking system where a slowly moving submarine acts as the docking station provides increased hydrodynamic control and reduces the impact of environmental disturbances. READ MORE

  4. 3. Assisted GNSS Positioning using State Space Corrections

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Oskar Philipsson; [2023]
    Keywords : positioning; GNSS; SSR; EKF; sensor fusion;

    Abstract : Classical GNSS based positioning has accuracy limitations due to many sources oferror. The error sources range from clock errors and orbit errors toerrors due to variations in atmospheric propagation delays. One way to improve GNSSpositioning is to generate real time corrections using a GNSS reference network. READ MORE

  5. 4. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Tim Wiik; [2022]
    Keywords : Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Abstract : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

  6. 5. Utilising Raw GNSS Data from Android Units to Improve Positioning

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Karin Seifert; [2022]
    Keywords : ;

    Abstract : In this study it was examined if positioning can be improved by utilising raw Global Navigation Satellite System (GNSS) data from Android devices instead of using Android's existing Location API. If this is the case, the coworkers at BM System may modify their apps, one is called Loco, to develop one that calculates positions directly by utilising raw GNSS data instead of using Android's Location API which is done presently.
