1. 1. Experiments with Visual Odometry for Hydrobatic Autonomous Underwater Vehicles

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

   Författare :Somnath Balaji Suresh Kumar; [2023]
   Nyckelord :Hydrobatic AUVs; VO; Stonefish; ORB-SLAM2; VISO2; Hydrobatiska AUV:er; VO; Stonefish; ORB-SLAM2; VISO2;

   Sammanfattning : Hydrobatic Autonomous Underwater Vehicles (AUVs) are underactuated robots that can perform agile maneuvers in challenging underwater environments with high efficiency in speed and range. The challenge lies in localizing and navigating these AUVs particularly for performing manipulation tasks because common sensors such as GPS become very unreliable underwater due to their poor accuracy.

3. 2. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Kim Klöckner; [2023]
   Nyckelord :NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

   Sammanfattning : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. LÄS MER

4. 3. Quadcopter stabilization based on IMU and Monocamera Fusion

   Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Arturo Pérez Rodríguez; [2023]
   Nyckelord :Machine Vision; Sensor Fusion; Unmanned Aerial Vehicles; Drone Stabilization; Frontal Monocamera;

   Sammanfattning : Unmanned aerial vehicles (UAVs), commonly known as drones, have revolutionized numerous fields ranging from aerial photography to surveillance and logistics. Achieving stable flight is essential for their successful operation, ensuring accurate data acquisition, reliable manoeuvring, and safe operation. LÄS MER

5. 4. Camera Distortion Calibration through Fringe Pattern Phase Analysis

   Master-uppsats, Linköpings universitet/Datorseende

   Författare :Karl Karlsson; [2023]
   Nyckelord :fringe-pattern; distortion; monogenic signal; phase analysis;

   Sammanfattning : The goal of this thesis is to use fringe-pattern phase analysis to calibrate the distortion of a camera lens. The benefit of using this method is that the distortion can be calculated using data from each individual pixel and the methodology does not need any model. LÄS MER

7. 5. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

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

   Författare :Kyle William Coble; [2023]
   Nyckelord :Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

   Sammanfattning : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. LÄS MER
