  1. 1. 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

  3. 2. Pixel correspondences for SLAM using sidescan sonar with canonical representations

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

    Author : Weiqi Xu; [2022]
    Keywords : ;

    Abstract : Acoustic instruments play an important role in autonomous underwater vehicles (AUVs). Sidescan sonar (SSS) detects a wider range, provides photo-realistic images in high resolution, and has lower price than the multibeam echo sounder (MBES). READ MORE

  4. 3. AUV SLAM constraint formation using side scan sonar

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

    Author : Marco Schouten; [2022]
    Keywords : AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Abstract : Autonomous underwater vehicle (AUV) navigation has been a challenging problem for a long time. Navigation is challenging due to the drift present in underwater environments and the lack of precise localisation systems such as GPS. Therefore, the uncertainty of the vehicle’s pose grows with the mission’s duration. READ MORE

  5. 4. Marine Habitat Mapping Using Image Enhancement Techniques & Machine Learning

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Mudasar Mureed; [2022]
    Keywords : Coral Reef; Habitat Mapping; Convolutional Neural Network; Transfer Learning; Fine Tuning; CLAHE;

    Abstract : AbstractThe mapping of habitats is the first step that is done in policies that target theenvironment, as well as in spatial planning and management. The biodiversityplans are always centered around habitats. Therefore, constant monitoring ofthese delicate species in terms of health, changes, and extinction is a must inbiodiversity plans.

  6. 5. Ocean Exploration with Artificial Intelligence

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Sarah Al-Khateeb; Lisa Bodlak; [2021-07-06]
    Keywords : computer science; deep learning; generative adversarial networks; data augmentation; object detection; underwater image; computer vision;

    Abstract : Large and diverse data is crucial to train object detection systems properly and achieve satisfactory prediction performance. However, in some areas, such as ma rine science, gathering sufficient data is challenging and sometimes even infeasible. Working with limited data can result in overfitting and poor performance.
