  1. 1. AUV SLAM constraint formation using side scan sonar

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marco Schouten; [2022]
    Nyckelord :AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation; AUV; Side Scan Sonar; Pose Estimation; SLAM; Optimisation;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : Along Sweden’s east coast there are thousands of well-preserved shipwrecks after an extensive shipping that stretches far back in history. The Baltic Sea is a unique sea in the sense that the ship worm Teredo Navalis cannot live here, which means that the ship’s timber is well preserved under water. LÄS MER

  4. 3. Canonical Representation of sidescan sonar images for robotics application

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hongsheng Chang; [2021]
    Nyckelord :;

    Sammanfattning : Sidescan sonar (SSS) is crucial in underwater investigation as it is cheaper and provide wider detection range. Sidescan sonars are typically mounted on Autonomous Underwater Vehicles (AUVs) or vessels. LÄS MER

  5. 4. Local Feature Correspondence on Side-Scan Sonar Seafloor Images

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Li Ling; [2021]
    Nyckelord :;

    Sammanfattning : In underwater environments, the perception and navigation systems are heavily dependent on the acoustic wave based sonar technology. Side-scan sonar (SSS) provides high-resolution, photo-realistic images of the seafloor at a relatively cheap price. LÄS MER

  7. 5. Machine Learning for Inferring Depth from Side-scan Sonar Images

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yiping Xie; [2019]
    Nyckelord :;

    Sammanfattning : Underwater navigation using Autonomous Underwater Vehicles (AUVs), which is significant for marine science research, highly depends on the acoustic method, sonar. Typically, AUVsare equipped with side-scan sonars and multibeam sonars at the same time since they both have their advantages and limitations. LÄS MER
