  1. 6. Monocular Visual Odometry for Autonomous Underwater Navigation : An analysis of learning-based monocular visual odometry approaches in underwater scenarios

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

    Author : Andrea Caraffa; [2021]
    Keywords : Deep Learning; Monocular Visual Odometry; Computer Vision; Autonomous Underwater Navigation; Autonomous Underwater Vehicle; Djupinlärning; Monokulär Visuell Odometri; Datorseende; Autonom Undervattensnavigering; Autonomt Undervattensfordon;

    Abstract : Visual Odometry (VO) is the process of estimating the relative motion of a vehicle by using solely image data gathered from the camera. In underwater environments, VO becomes extremely challenging but valuable since ordinary sensors for on-road localization are usually unpractical in these hostile environments. READ MORE

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

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

    Author : Hongsheng Chang; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  4. 8. Multi-method based characterization of calving events at Sálajiegna Glacier - Lake Sulitelma, Northern Sweden

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Martin Schulthess; [2021]
    Keywords : Glaciology; Glacier; Glaciers; Calving; calving front; detection algorithm; Acoustic; Acoustics; Photogrammetry; ice-ocean interactions; UAV; drone; time-lapse; Salajiegna;

    Abstract : Sea level rise concerns millions of people in coastal areas across the globe. One of the largest uncertainties to project future sea level rise is the frontal ablation (accounting for calving and submarine melt) at marine ice margins, around the Greenland and Antarctic Ice Sheet.

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

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

    Author : Li Ling; [2021]
    Keywords : ;

    Abstract : 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. READ MORE

  6. 10. Combining Sidescan Sonar and Multibeam Echo Sounder to Improve Bathymetric Resolution per Ping

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

    Author : Filip Hestell; [2021]
    Keywords : ;

    Abstract : The master thesis degree project is carried out in the area of robotics, particularly in the area of autonomous underwater vehicles (AUV) and seafloor mapping. The goal of this degree project is to investigate if sidescan sonar data can be used to increase the bathymetric resolution. READ MORE
