  1. 1. Potentialities of Unmanned Aerial Vehicles in Hydraulic Modelling : Drone remote sensing through photogrammetry for 1D flow numerical modelling

    Master-uppsats, KTH/Byggvetenskap

    Författare :Andrea Reali; [2018]
    Nyckelord :UAV; remote sensing; structure from motion; photogrammetry; 1D steady flow hydraulic numerical modelling; hydraulic modelling;

    Sammanfattning : In civil and environmental engineering numerous are the applications that require prior collection of data on the ground. When it comes to hydraulic modelling, valuable topographic and morphology features of the region are one of the most useful of them, yet often unavailable, expensive or difficult to obtain. LÄS MER

  2. 2. Early detection and recommendation of higher precision in treatment of late blight in potato crops by using drone photos

    Master-uppsats, Lunds universitet/Riskhantering (CI)

    Författare :Anna Lindéus; [2018]
    Nyckelord :Bayesian network; Decision Support systems; Drone photo; Late blight; Potato; Precision Agriculture; Remote sensing; Risk classification model; Risk prediction; Technology and Engineering;

    Sammanfattning : In this thesis an evaluation was performed for the potential use of drone photos in Decision Support System (DSS) to detect outbreak of late blight and provide recommend treatment with fungicides. Late blight is a common crop infection on potato in Sweden. A DSS with and without information from drones were developed in three steps. LÄS MER

  3. 3. Planning semi-autonomous drone photo missions in Google Earth

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för data- och systemvetenskap

    Författare :Per Johan Fredrik Nilsson; [2017]
    Nyckelord :Google Earth; Robotics; Pathfinding; A*; Theta*; Path smoothing; Traveling Salesman Problem; Branch-and-Bound; Swift; C ;

    Sammanfattning : This report covers an investigation of the methods and algorithms required to plan and perform semi-autonomous photo missions on Apple iPad devices using data exported from Google Earth. Flight time was to be minimized, taking wind velocity and aircraft performance into account. LÄS MER
