  1. 11. Tracking motion in mineshafts : Using monocular visual odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Karl Suikki; [2022]
    Nyckelord :Monocular Visual Odometry; Tracking; ORB; SIFT;

    Sammanfattning : LKAB has a mineshaft trolley used for scanning mineshafts. It is suspended down into a mineshaft by wire, scanning the mineshaft on both descent and ascent using two LiDAR (Light Detection And Ranging) sensors and an IMU (Internal Measurement Unit) used for tracking the position.

  3. 12. Detecting and comparing Kanban boards using Computer Vision

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

    Författare :Humam Behnam; [2022]
    Nyckelord :Kanban Board; Sticky Notes; Computer Vison; OpenCV; Feature Detection; Feature Matching; Canny Edges; Contours; Perspective Transformation; Text Detection; Kanbantavla; Klisterlappar; Datorseende; OpenCV; Funktionsdetektering; Funktionsmatchning; Cannykanter; Konturer; Perspektivförvandling; Textigenkänning;

    Sammanfattning : This thesis investigates the problem of detecting and tracking sticky notes on Kanban boards using classical computer vision techniques. Currently, there exists some alternatives for digitizing sticky notes, but none keep track of notes that have already been digitized, allowing for duplicate notes to be created when scanning multiple images of the same Kanban board.

  4. 13. FPGA Implementation of Feature Matching in ORB-SLAM2

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hannah Lindström; [2022]
    Nyckelord :Autonomous navigation; SLAM; Feature matching; FPGA; ORB; Heterogeneous binary tree; Technology and Engineering;

    Sammanfattning : Simultaneous Localization And Mapping (SLAM) is an important component in solving the problem of autonomous navigation — allowing machines such as selfdriving cars and mobile robots to find their way in the world without human instruction. Though there is a steadily growing body of literature in the field of SLAM, far fewer works currently address using hardware acceleration to speed up this computationally heavy task. LÄS MER

  5. 14. 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. 15. Adaptive Losses for Camera Pose Supervision

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Marcus Dahlqvist; [2021]
    Nyckelord :camera pose supervision; camera pose; local features; feature descriptors; dense feature descriptors; correspondence image matching; feature matching;

    Sammanfattning : This master thesis studies the learning of dense feature descriptors where camera poses are the only supervisory signal. The use of camera poses as a supervisory signal has only been published once before, and this thesis expands on this previous work by utilizing a couple of different techniques meant increase the robustness of the method, which is particularly important when not having access to ground-truth correspondences.
