  1. 21. Structure from Motion, a Cheaper Alternative for Three-Dimensional Modeling in Earth Science

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Viktor Fagerström; [2018]
    Keywords : Structure from Motion; photogrammetry; WebODM; “terrestrial laser scanning”; “open software”; Structure-from-Motion; Fotogrammetri; WebODM; LiDAR; markbunden laser-scanning; öppen källkod;

    Abstract : In this report, two methods for three-dimensional modeling are evaluated against each other. The first method is terrestrial laser scanning (LiDAR) that uses a laser beam to record the surrounding environment, and the second one is called Structure from Motion (SfM). READ MORE

  3. 22. Kontrolltaxering med stöd av drönare hos Norra Skogsägarna

    University essay from SLU/Dept. of Forest Resource Management

    Author : Oscar Jakobsson; [2017]
    Keywords : fotogrammetri; UAV; inventering; inventeringsdesign;

    Abstract : Varje år framställer Norra Skogsägarna ett stort antal skogsbruksplaner som måste uppfylla bestämda kvalitetskrav. Målet med studien är att med stöd av en drönare monterad med kamera utveckla kvalitetssäkringen av de skogsbruksplaner Norra Skogsägarna framställer. READ MORE

  4. 23. Unmanned Aerial Vehicles for Geographic Data Capture: A Review

    University essay from KTH/Geodesi och satellitpositionering

    Author : Hanna Gustafsson; Lea Zuna; [2017]
    Keywords : UAV; Drones; Geographic data collection;

    Abstract : In GIS-projects the data capture is one of the most time consuming processes. Both how to collect the data and the quality of the collected data is of high importance. Common methods for data capture are GPS, LiDAR, Total Station and Aerial Photogrammetry. READ MORE

  5. 24. Comparison of Photogrammetry Interpretation with Physical Structural Field Measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Osterman; [2017]
    Keywords : Fracture mapping; photogrammetry; 3D-modelling; rock classification; field safety; Sprickkartering; fotogrammetri; 3D-modellering; bergklassificering; säkerhet i fält;

    Abstract : Fracture mapping of bedrock and knowledge about how fractures influence rock strength and stability is of great importance in a constructional context. These factors largely dictate where one can build and not build in rock, and to what extent reinforcements and safety measurements are needed. READ MORE

  6. 25. MEASUREMENT AND MODELLING OF MULTICOPTER UAS ROTOR BLADE DEFLECTION IN HOVER

    University essay from KTH/Lättkonstruktioner

    Author : Nathalie Nowicki; [2016]
    Keywords : ;

    Abstract : Package deliveries, surveillance and entertainment are all areas where unmanned aerial systems, (UAS), face a growing market. Multicopters, being one of the most popular UAS, can both be bought and built rather easily due to the fairly simple design and low cost. READ MORE
