  1. 21. 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

  3. 22. Testing aerosol vertical profiling methods with portable instruments on unmanned and manned aircraft

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Ellen Grace Soroka; [2023]
    Nyckelord :Physical Geography; Ecosystem Analysis; Aerosols; Vertical Profile; Black Carbon; PM2.5; Nanoparticles; UAV; Drone; Master degree thesis; 30 credits in Atmospheric Science Biogeochemical Cycles; Earth and Environmental Sciences;

    Sammanfattning : This thesis employed several portable sensors on board an unmanned aerial vehicle (UAV) and manned aircraft in order to test new methods of measuring vertical profiles of aerosol particles and contribute to knowledge of aerosol distributions in the atmosphere. More data in this area is required to improve atmospheric modelling and future climate scenarios. LÄS MER

  4. 23. Coverage Motion Planning for Search and Rescue Missions : A Costmap Based Approach for fixed wing UAVs using Simulated Annealing &Cubic Splines

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Fredrik Rönnkvist; [2023]
    Nyckelord :Motion planning; Path planning; Cubic splines; Coverage path planning.;

    Sammanfattning : The present study proposes a novel approach to Coverage Path Planning for unmanned aerial vehicle (UAV) inspired by the Orienteering Problem. The main goal is to develop an algorithm suitable for Search and Rescue Missions, which can produce a search pattern with dynamical constrains, that is not limited to the traditional back-and-forth motion or spiral patterns.

    Sammanfattning : This project presents a motion planning algorithm for an unmanned aerial vehicle (UAV).UAVs have become more popular in recent years because of their maneuverability. This has causedthe need for motion planning algorithms to increase. LÄS MER

  7. 25. Optimization-Based Path Planning For Indoor UAVs in an Autonomous Exploration Framework

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

    Författare :Marco Cella; [2023]
    Nyckelord :Optimal Path Planning; B-Splines; Autonomous Exploration; Indoor UAV; Crisis and Disaster Management; Trajectory Estimation; SITL; Optimal Banplanering; B-Splines; Autonom Utforskning; Inomhus-UAV; Kris- och Katastrofhantering; Uppskattning av Banor; SITL;

    Sammanfattning : Exploration is a fundamental problem in robotics that requires robots to navigate through unknown environments to autonomously gather information about their surroundings while executing collision-free paths. In this project, we propose a method for producing smooth paths during the exploration process in indoor environments using UAVs to improve battery efficiency and enhance the quality of pose estimation.
