  1. 11. 3D Reconstruction from Satellite Imagery Using Deep Learning

    University essay from Linköpings universitet/Datorseende

    Author : Tim Yngesjö; [2021]
    Keywords : 3D reconstruction; Deep learning;

    Abstract : Learning-based multi-view stereo (MVS) has shown promising results in the domain of general 3D reconstruction. However, no work before this thesis has applied learning-based MVS to urban 3D reconstruction from satellite images. In this thesis, learning-based MVS is used to infer depth maps from satellite images. READ MORE

  3. 12. Methods for assessing the consistency of the New National Height Model

    University essay from KTH/Fastigheter och byggande

    Author : Sandra Rangelova; [2021]
    Keywords : DEM; LiDAR; Air-borne LiDAR; strip adjustment; quality control; DEM; LiDAR; Luftburna LiDAR; bandjustering; kvalitetskontroll;

    Abstract : Digital Elevation Models (DEM) are a simple representation of the Earth’s surface. DEMs play an important role in the field of remote sensing and GIS and are used as basis for mapping and analysis for a vest majority of scientific applications. READ MORE

  4. 13. Methods for rockfall risk assessment and estimation of runout zones: A case study in Gothenburg, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Laura Catalina Agudelo Motta; [2020]
    Keywords : Rockfall hazard; rockfall simulation; Gothenburg; Fjällbo; runout zones; Earth and Environmental Sciences;

    Abstract : Rockfalls occur around Sweden every year and the country lacks a national risk evaluation and an adequate regulatory framework for construction related to this natural hazard. The aim of this study is to address this problem by mapping areas under possible threat of rockfalls, considering two fundamental aspects: i) identification of the source areas and ii) estimation of the runout zones.

  5. 14. Material parameter identification of a thermoplastic using full-field calibration

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Nikhil Prabhu; [2020]
    Keywords : DIC; FFC; Thermoplastics; Material parameter identification; multi-point history; Polyamide 6; GISSMO; Response Surface Methodology;

    Abstract : Finite element simulation of thermoplastic components is gaining importance as the companies aim to avoid overdesign of the components. Cost of the component can be minimized by using an adequate amount of material for its application. READ MORE

  6. 15. Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Jip Jan van Zoonen; [2020]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Digital Elevation Model; DEM; Glaciology; Earth and Environmental Sciences;

    Abstract : Aspects of Error Quantification and Evaluation in Digital Elevation Models for Glacier Surfaces This study explores methods to quantify and evaluate error in digital elevation models (DEMs) built from remotely sensed elevation data of the Hintereisferner glacier. A special focus lies on glacier surfaces because glaciers are often inaccessible for field observations but at the same time prone to measurement errors. READ MORE
