1. 1. Using NeRF- and Mesh-Based Methods to Improve Visualisation of Point Clouds

   University essay from Lunds universitet/Matematik LTH

   Author : Vilma Ylvén; Oscar Montelin; [2024]
   Keywords : Technology and Engineering; Mathematics and Statistics;

   Abstract : In recent years, the field of generating synthetic images from novel view points has seen some major improvements. Most importantly with the publication of Neural Radiance Fields allowing for extremely detailed and accurate 3D novel views. READ MORE

3. 2. Effectiveness of Iterative Algorithms for Recovering Phase in the Presence of Noise for Coherent Diffractive Imaging

   University essay from Göteborgs universitet / Institutionen för fysik

   Author : Henry Wittler; [2023-11-29]
   Keywords : ;

   Abstract : Methods of coherent diffractive imaging (CDI) rely on iterative algorithms to reconstruct the complex exit-surface wave (ESW) of the object being imaged from the measured diffraction intensity only. In this thesis we investigate by simulation the artifacts on reconstruction when noise are present in the measurement. READ MORE

4. 3. Surface Reconstruction using Multipath Propagation in Indoor MIMO Radar

   University essay from Lunds universitet/Matematisk statistik

   Author : Elias Olson; Jakob Henningsson; [2023]
   Keywords : Multiple-input multiple-output MIMO radar; multipath recognition; geometry reconstruction; Mathematics and Statistics;

   Abstract : Using active radar for localization in indoor environments is challenging. By signal reflection off walls and other static objects, false targets occur, referred to as multipath "ghosts". These are a significant hinder in interpreting the data. READ MORE

5. 4. Streamlining 3D City Modeling for Urban Flow Simulations by Automatic Integration of Multisource Topography

   University essay from Umeå universitet/Institutionen för fysik

   Author : Klara Lindroth; [2023]
   Keywords : automatic 3D city models; surface reconstruction; geometry pre-processing; CFD; OSM height attributes;

   Abstract : In the workflow of computational fluid dynamics, geometry preparation is commonly the most time-consuming step. For a fast CFD simulation, automatic surface reconstruction to obtain 3D city models for a chosen area is essential. To address this need, a literature study was conducted to map available data suitable for 3D city models. READ MORE

6. 5. Image Analysis for Compliant Measurements and Calibration of Visual Projector Systems

   University essay from Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

   Author : Daniel Westberg; [2023]
   Keywords : Absolute Geometry; Absolute Surface Shape; Three-dimensional Reconstruction; Flight Simulator; Projector Calibration;

   Abstract : A realistic visualization that enhances a virtually authentic experience is the ambition of any visualization system in a simulator environment. But calibrating and maintaining a high quality visualization system entail large costs, resources and time. READ MORE
