  1. 11. Acoustic-Inertial Forward-Scan Sonar Simultaneous Localization and Mapping

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

    Author : Aldo Teran Espinoza; [2020]
    Keywords : ;

    Abstract : The increasing accessibility and versatility of forward-scan (FS) imaging sonars (also known as forward looking sonars or FLS) has spurred the interest of the robotics community seeking to solve the difficult problem of robotic perception in low-visibility underwater scenarios. Processing the incoming data from an imaging sonar is challenging, since it captures an acoustic 2D image of the 3D scene instead of providing straightforward range measurements like other sonar technologies do (e.

  3. 12. Semantic segmentation of seabed sonar imagery using deep learning

    University essay from Linköpings universitet/Programvara och system

    Author : Petter Granli; [2019]
    Keywords : ;

    Abstract : For investigating the large parts of the ocean which have yet to be mapped, there is a need for autonomous underwater vehicles. Current state-of-the-art underwater positioning often relies on external data from other vessels or beacons. Processing seabed image data could potentially improve autonomy for underwater vehicles.

  4. 13. Implementation of an object-detection algorithm on a CPU+GPU target

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Gautier Berthou; [2016]
    Keywords : Object detection; Parallel processing; GPGPU; Haar-like features; Objektdetektering; Parallel bearbetning; GPGPU; Haar-lika egenskaper;

    Abstract : Systems like autonomous vehicles may require real time embedded image processing under hardware constraints. This paper provides directions to design time and resource efficient Haar cascade detection algorithms. It also reviews some software architecture and hardware aspects. READ MORE

  5. 14. Real-time fish type recognition in underwater images for sustainable fishing

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Fritjof Jonsson; [2015]
    Keywords : ;

    Abstract : It has been investigated if it is possible to selectivly catch farmed salmon (Salmo salar L., 1758) and sea trout (Salmo trutta L., 1758) without disturbing the wild fish. A image analysis software that can separate wild from farmed salmon and salmon from sea trout has been developed. READ MORE

  6. 15. Distributed Underwater Sonar

    University essay from Akademin för innovation, design och teknik

    Author : Ukrit Meesangphrao; [2011]
    Keywords : underwater sonar; distributed sonar;

    Abstract : This thesis is focused on possibility of constructing distributed underwater sonar which has an ability to increase or decrease number of sensor elements without any modification on its hardware. Each sonar module works individually. READ MORE
