  1. 1. Flood Simulation in the Colombian Andean Region Using UAV-based LiDAR : Minor Field Study in Colombia

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Simon Höglund; Linus Rodin; [2023]
    Nyckelord :UAV; Unmanned aerial vehicle; LiDAR; Light detection and ranging; UAV-based LiDAR; UAV photogrammetry; Aerial photogrammetry; Flooding Colombia; UN Sustainability Development Goals; UAV; Obemannade flygfordon; LiDAR; Ljus- och avståndsdetektion; UAV-baserad LiDAR; UAV-fotogrammetri; Flygfotogrammetri; Översvämning Colombia; FN; hållbarhetsutvecklingsmål;

    Sammanfattning : Flooding is a worldwide problem that every year causes substantial damage for the environment and stakeholders nearby, and this impact relates to several of the United Nations Sustainable Development Goals. Colombia is specially prone to flooding as 17% of its surface area is at risk of extreme flooding. LÄS MER

  3. 2. A Photogrammetric Workflow to Produce 3D-Models of Geological Samples

    Kandidat-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Fanny Bjugger; [2023]
    Nyckelord :photogrammetry; S-f-M; digital 3D models; geoscience; rock samples; earth sciences;

    Sammanfattning : Photogrammetry and Structure-from-Motion (S-f-M) is a low-cost method of producing digital 3D models of rock samples that can be used for many different research and educational purposes. A 3D model of a delicate rock sample would enable the preservation of the sample and reduce the need of physical manipulation. LÄS MER

  4. 3. Trunk Poetry

    Uppsats för yrkesexamina på avancerad nivå, KTH/Arkitektur

    Författare :Moa Eriksson Takman; [2023]
    Nyckelord :full scale;

    Sammanfattning : Trunk poetry is an investigation of a tree, its natural form shaped by its environment, how it can be disassembled and understood through different methods and tools, and how its parts can be reassembled to form structural elements based on the capacity of the natural forms. This research consists of three phases which are a combination of a historical perspective on identifying and harvesting construction timber, digital processing such as photogrammetry and physical experiments connected to the construction of structural elements.

  5. 4. Transcending Memories Beyond Borders: Carrying Memorabilia from Home to Abroad. : Transferring Personal Memorabilia for a Meaningful Cross-Country Experience.

    Master-uppsats, Uppsala universitet/Människa-datorinteraktion

    Författare :Ruby Abeywickrama; [2023]
    Nyckelord :Migrants; Souvenirs; Culture; Preservation; Research through design; Materiality; Physical to digital; rematerialization; 3D printing; Augmented Reality; Identity; Symbolic Values;

    Sammanfattning : Collecting memorabilia has been a longstanding practice as it evolved around cultures and societies. Despite existing research about preserving memorabilia, meaningful preservation methods remain unclear due to the individual and idiosyncratic nature of practices [18,22,40,43,47,59]. LÄS MER

  7. 5. Deformationsmätning av kubhörnsreflektorer med fotobaserad skanning och terrester laserskanning

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Erkkilä; Torkel Pettersson; [2022]
    Nyckelord :close-range photogrammetry; terrestrial laser scanning; deformation measurement; corner reflectors; InSAR; fotobaserad skanning; Terrester laserskanning; deformationsmätning; kubhörnsreflektor; InSAR;

    Sammanfattning : Kubhörnsreflektorer används som måltavlor med kontinuerlig och identifierbar reflekterad signalstyrka vid fjärranalys, bland annat för tekniken ”interferometric synthetic aperture radar” [InSAR]. Kubhörnsreflektorer tillämpas exempelvis för bevakning av sättningar i jordytan och kalibrering av [SAR]-system (”synthetic aperture radar”). LÄS MER
