  1. 31. Volymberäkning från punktmoln skapatgenom Structure from Motion medbildunderlag från mobilkamera

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Andreas Sigurdsson; Amadeus Lehr; [2021]
    Nyckelord :Structure from Motion; Smartphone camera; Volume calculation; 3Dmodelling; Digital photogrammetry.; Structure from Motion; Mobilkamera; volymberäkning; 3D-modellering; digital fotogrammetri.;

    Sammanfattning : Tekniken hos mobiler och utvecklingen av programvaror för digitalafotogrammetriska tjänster har haft en snabb utveckling, vilket har gjort detmöjligt att enkelt kunna skapa 3D-modeller.Syftet med denna studie är att undersöka om det är möjligt att med hjälp avbildunderlag från en mobiltelefon kunna volymberäkna objekt så som t.ex.

  3. 32. Deflection measurements with 3D close range photogrammetry

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Guillaume Defromont; [2021]
    Nyckelord :Photogrammetry; Computer Science; Optimization; Aero-elasticity; Fotogrammetry; Datvetenskap; Aeroelasticitet;

    Sammanfattning : Photogrammetry is a great technology to check and track deformations on anysurface. This information is critical in many tranportation industries such as aeronautics and the automotive industry. In this thesis report photogrammetry measurements were done using 2 Aicon cameras providing 3D targets coordinates. LÄS MER

  4. 33. Faster Environment Modelling and Integration into Virtual Reality Simulations

    Magister-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Jonas Nyman; [2021]
    Nyckelord :3D re-construction; Digital Photogrammetry; LiDAR; Remote Sensing; Point Cloud; Point cloud to mesh; Terrestrial Laser Scanning; Static Laser scan; Virtual Reality;

    Sammanfattning : The use of virtual reality in engineering tasks, such as in virtual commissioning, has increased steadily in recent years, where a robot, machine or object of interest can be simulated and visualized. Yet, for a more immerse experience, an environment for the object in question needs to be constructed. LÄS MER

  5. 34. Volume Calculation Based on LiDAR Data

    Master-uppsats, KTH/Fastigheter och byggande

    Författare :Worlanyo Yao Amaglo; [2021]
    Nyckelord :laser scanning; volume; stockpile; Photogrammetry; ALS; TLS; mining; MATLAB; SfM; laserskanning; volym; lagerföra; fotogrammetri; ALS; TLS; gruvdrift; MATLAB; SfM;

    Sammanfattning : In this thesis project, the main objective is to compare and evaluate different surveying methodsfor volume determination; Photogrammetry, Terrestrial Laser Scanning(TLS) and Aerial LaserScanning (ALS) based on time consumption, efficiency and safety in the mining industry. In addition,a volumetric computational method based on coordinates would be formulated to estimatethe volume of stockpiles using lidar data captured with a laser scanner. LÄS MER

  7. 35. Drones in Civil Engineering Projects : Areas of Application With a Focus On Photogrammetry

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Martin Matte; Daniel Rangne; [2021]
    Nyckelord :drones; photogrammetry; 3D-models; volumetric calculations; civil engineering; mapping; drönare; fotogrammetri; 3D-modell; volymberäkningar; anläggning; kartering;

    Sammanfattning : Drone technology has changed the way people work in construction and civil engineering activities. The aim of this report is to investigate how drones can and should be used in the best possible way. Autodesk ReCap Photo and Agisoft Metashape Professional are the two photogrammetry software programs that have been compared. LÄS MER
