  1. 1. An investigation of detecting potholes with UAV LiDAR and UAV Photogrammetry

    University essay from Högskolan i Gävle/Samhällsbyggnad

    Author : Linus Hedenström; Sebastian Eriksson; [2021]
    Keywords : UAV; LiDAR; photogrammetry; potholes; point clouds; SfM; paved; pavement; road; drone; UAV; LiDAR; fotogrammetri; potthål; drönare; asfalt; väg; punktmoln; SfM;

    Abstract : Potholes are caused by erosion and as such always emerging on our roadnetwork. Potholes may not only cause great damages to vehicles, but can alsocause road accidents, which in the worst case are fatal. READ MORE

  3. 2. 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

  4. 3. Photogrammetry for health monitoring of bridges : Using point clouds for deflection measurements and as-built BIM modelling

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Joel Delehag Lundmark; [2019]
    Keywords : ;

    Abstract : Road and railway bridges play a crucial role for the infrastructure network in Sweden to work smoothly and keep the traffic flowing. Damage to a bridge can have catastrophic consequences if they are not corrected properly and in due time. READ MORE

    Abstract : The master ‘s thesis focused on forest inventory process based on the photogrammetric point cloud. The study deals with forest stand data collecting using terrestrial and aerial photogrammetry. READ MORE

  6. 5. Photogrammetric 3d-mapping using low-cost unmanned aerial vehicle - Analysis of accuracy

    University essay from Lunds universitet

    Author : Johan Svensson; Alex Andersson; [2018]
    Keywords : drone; uav; photogrammetry; point cloud; bim; Technology and Engineering;

    Abstract : The UAV (unmanned aerial vehicle) is a part of the digital transformation in the construction industry. With increased options of low-cost UAVs, more companies will want to integrate UAVs into their business. By capturing a large amount of data in a short time, it could be very useful for several applications within the construction industry. READ MORE
