Xu, Yabin (author), Nan, L. (author), Zhou, Laishui (author), Wang, Jun (author), Wang, C.C. (author)Reconstruction of high-fidelity 3D objects or scenes is a fundamental research problem. Recent advances in RGB-D fusion have demonstrated the potential of producing 3D models from consumer-level RGB-D cameras. However, due to the discrete nature and limited resolution of their surface representations (e.g., point or voxel based), existing...journal article 2022

Markhorst, Thomas (author)Proper maintenance and inspection of aircraft and their engines is important for society. These engine inspections are performed using borescopes of which the footage is manually analysed. Having the opportunity to reconstruct a 3D model of the rotors would ease the inspection and introduce the possibility to automate the process. Monocular SLAM...bachelor thesis 2021

Nonnemaker, Alec (author)To aid in damage assessment, creating 3D reconstruction from borescope videos of jet engines could be very beneficial. However, jet engines often have shiny and non-textured surfaces, and the performance of 3D reconstruction methods is unknown in this case. This paper aims to qualitatively and quantitatively evaluate Structure from Motion (SfM)...bachelor thesis 2021

Lieuw A Soe, Devin (author)With 3D reconstruction from borescope videos of jet engines, inspections can be made more efficient. Being able to reconstruct 3D models of the jet engines potentially contributes to making the inspections autonomous. Methods that will be used for this reconstruction require to be evaluated to ensure the accuracy of the 3D models that they...bachelor thesis 2021

Tongel, Alexander Van (author), Wilde, Lieven De (author), Shimamura, Yasunori (author), Sijbers, Jan (author), Huysmans, T. (author)Current classifications of midshaft clavicle fractures are based on radiography. The aim of the study was to evaluate the fracture pattern of clavicle fractures using 3-dimensional computed tomography (3D CT). A retrospective analysis was performed on CT scans of 65 acute clavicle fractures. Using quantitative 3D CT reconstruction techniques,...journal article 2021
