  1. 1. Flying Wing Drone Impact Study

    Master-uppsats, KTH/Flygdynamik

    Författare :Sara Nilsson; [2021]
    Nyckelord :Flying wing drone; Regulations; Risk assessmen; Mathematical modeling; Material properties; Flygande vinge; regelverk; riskbedömning; matematisk modellering; materialegenskaper;

    Sammanfattning : The Swedish Sea Rescue Society (SSRS) is exploring how small, remotely launched drones can help in making the rescue work safer and more efficient. The planned drone to be used for such purposes is a 1 kg, 1 m wide, foam constructed, flying wing drone. LÄS MER

  3. 2. Analys av lägesosäkerheter hos fotogrammetriskt framställda DTM - en jämförelse mellan två programvaror

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Olivia Sköld; [2020]
    Nyckelord :Photogrammetry; UAV UAS Unmanned Aircraft Vehicle System ; Digital Terrain Model DTM ; Control Calculations; Fotogrammetri; UAV UAS Unmanned Aircraft Vehicle System ; digital terrängmodell DTM ; kontrollberäkningar;

    Sammanfattning : Idag blir användningen av drönare allt mer vanlig för dokumentation av markytor. Det är ett billigare alternativ för att dokumentera små och otillgängliga områden. Genom tekniken går det bland annat att framställa olika digitala modeller som representerar jordens yta. LÄS MER

  4. 3. Modeling and characterization of forest stands using aerial and terrestrial photogrammetry

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Simon Trcka; [2019]
    Nyckelord :UAV; structure from motion; remote sensing; diameter at breast height; UAS; drone; photogrammetry; forest inventory; tree height; stem volume; stand model;

    Sammanfattning : The master ‘s thesis focused on forest inventory process based on the photogrammetric point cloud. The study deals with forest stand data collecting using terrestrial and aerial photogrammetry. LÄS MER

  5. 4. Evaluation of digital terrain models created in post processing software for UAS-data : Focused on point clouds created through block adjustment and dense image matching

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad, GIS

    Författare :Sabina Assefha; Matilda Sandell; [2018]
    Nyckelord :UAS; DTM; Pix4D; UAS Master; Block adjustment; Photogrammetry; UAS; DTM; Pix4D; UAS Master; Blockutjämning; Fotogrammetri;

    Sammanfattning : Lately Unmanned Aerial Systems (UAS) are used more frequently in surveying. With broader use comes higher demands on the uncertainty in such measurements. The post processing software is an important factor that affects the uncertainty in the finished product. LÄS MER

  7. 5. UAVs for railway infrastructure operations and maintenance activities

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :MADELEINE SHEIKH; ALEXANDER ÖRTENGREN; [2018]
    Nyckelord :: UAV; UAS; Drone; Railway; Maintenance; Infrastructure; Operations; Remote inspection; Research; Autonomous; Rotor; Fixed-wing; UAV; UAS; Drönare; Järnväg; Underhåll; Infrastruktur; Drift; Fjärrinspektion; Autonom; Rotor; Fixed-wing.;

    Sammanfattning : The railway infrastructure needs to be safe, reliable and efficient in order to meet the growing demand of sustainable transportation methods. One of the main problems the railway industry faces today is that a higher traffic load increases the need for maintenance, at the same time as it reduces the availability of gaps in the timetables to perform maintenance activities.
