  1. 21. Underwater Change Detection by Fusing Multiple Sonar Images

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

    Author : Daniel Eriksson; [2019]
    Keywords : ;

    Abstract : Underwater change detection can be used for monitoring the seafloor and automatically alert when something changes on it. This could be especially useful in harbors or other critical sea-infrastructure. READ MORE

  3. 22. Monocular Visual Odometry for Underwater Navigation : An examination of the performance of two methods

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

    Author : Maxime Voisin-Denoual; [2018]
    Keywords : Visual Odometry; Orbslam; AUV; autonomous underwater vehicle; monocular;

    Abstract : This thesis examines two methods for monocular visual odometry, FAST + KLT and ORBSLAM2, in the case of underwater environments.This is done by implementing and testing the methods on different underwater datasets. The results for the FAST + KLT provide no evidence that this method is effective in underwater settings. READ MORE

  4. 23. Generic 6-DOF Added Mass Formulation for Arbitrary Underwater Vehicles based on Existing Semi-Empirical Methods

    University essay from KTH/Marina system

    Author : Josefine Severholt; [2017]
    Keywords : ;

    Abstract : The KTH Maritime Robotics Lab is developing a simulation framework for experimental autonomous underwater vehicles in MATLAB and Simulink. This project has developed a formulation for added mass of the vehicle, to be implemented in this simulation frame-work. READ MORE

  5. 24. Evaluation of the LSTS Toolchain for Networked Vehicle Systems on KTH Autonomous Maritime Vehicles

    University essay from KTH/Marina system

    Author : Elias Strandell Erstorp; [2015]
    Keywords : ;

    Abstract : The department of Naval Architecture at the Royal Institute of Technology is in posession of one Autonomous Underwater Vehicle (AUV) and a second is under construction. A project for doing hydrographic mapping using an Autonomous Surface Vehicle (ASV) is also initiated. READ MORE

  6. 25. Application for Debugging and Calibration of an Underwater Robot

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Patrik Lannebjer; Alexander Forssman; [2014]
    Keywords : AUV; calibration; debugging; logging; Zlog; Log4c; grammar; lexical analysis; parsing; TCP; UDP;

    Abstract : In this thesis we present a suitable way of calibrating and debugging an autonomous underwater vehicle (AUV). The issues that occur when working with an AUV are the inconvenient way of having to constantly recompile the software to change the behavior of the AUV and the lack of feedbacksreceived. READ MORE
