  1. 1. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

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

    Author : Somnath Balaji Suresh Kumar; [2023]
    Keywords : Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

    Abstract : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

  3. 2. Robust Non-Linear State Estimation for Underwater Acoustic Localization : Expanding on Gaussian Mixture Methods

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

    Author : Diogo Antunes; [2023]
    Keywords : Robust state estimation; Underwater localization; Target tracking; Gaussian mixture; AUV; Estimação robusta de estado; Localização subaquática; Rastreamento de alvos; Mistura Gaussiana; AUV; Robust tillståndsuppskattning; Undervattenslokalisering; Målspårning; Gaussisk blandning; AUV;

    Abstract : Robust state estimation solutions must deal with faulty measurements, called outliers, and unknown data associations, which lead to multiple feasible hypotheses. Take, for instance, the scenario of tracking two indistinguishable targets based on position measurements, where each measurement could refer to either of the targets or even be a faulty reading.

  4. 3. AUV SLAM for Algae Farm Inspection : 3D Mosaicing using Sonar-Based SLAM

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

    Author : Julian Valdez; [2023]
    Keywords : ;

    Abstract : The progression of seaweed farming and cultivation to an industrial scale relies on automating its processes. Utilization of Autonomous Underwater Vehicle (AUV) can enable this process through their capacity to automate crop and structural inspections. READ MORE

  5. 4. Submap Correspondences for Bathymetric SLAM Using Deep Neural Networks

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

    Author : Jiarui Tan; [2022]
    Keywords : Underwater simultaneous localization and mapping; Multibeam echosounder; Point cloud registration; Deep learning; Undervattens simultan lokalisering och kartläggning; Multibeam ekolod; Punktmolnsregistrering; Djupinlärning;

    Abstract : Underwater navigation is a key technology for exploring the oceans and exploiting their resources. For autonomous underwater vehicles (AUVs) to explore the marine environment efficiently and securely, underwater simultaneous localization and mapping (SLAM) systems are often indispensable due to the lack of the global positioning system (GPS).

  6. 5. Terrain Referenced Navigation with Path Optimization : Optimizing Navigation Accuracy by Path Planning

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

    Author : Martin Gelin; [2022]
    Keywords : Terrain Referenced Navigation; Localization; Particle Filter; Rao-Blackwellized Particle Filter; Kalman Filter; Path Planning; Terrängbaserad navigering; Lokalisering; Partikelfilter; Rao-Blackwelliserat partikelfilter; Kalmanfilter; Banplanering;

    Abstract : Terrain referenced navigation is a method of navigation that uses measurements of altitude above ground to infer the position of the vehicle, mainly aerial or underwater. This method provides an alternative to the commonly used satellite-based navigation. READ MORE
