  1. 1. Volume Calculation Based on LiDAR Data

    University essay from KTH/Fastigheter och byggande

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

    Abstract : 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. READ MORE

  6. 5. Observering Digitally - The use of Image-Based 3D Modelling Techniques for the documentation and study of Rune Stones

    University essay from Lunds universitet/Historisk arkeologi

    Author : Rasmus Friberg; [2015]
    Keywords : Rune Stone; Image Based Modelling; Low Cost; Documentation; Viking Age; Agisoft Photoscan; Meshlab; Radiance scaling; 3D; History and Archaeology;

    Abstract : This thesis aims to test and evaluate the use of image-based 3D modelling techniques on rune stones. To test the method a well-documented rune stone was chosen, Hyby stone 1. The stone has been dated to the Viking Age and contains 37 runes, whereof 29 are still visible, two crosses and a stag. READ MORE
