  1. 1. Evaluation of SLAM based mobile laser scanning and terrestrial laser scanning in the Kiruna mine : A comparison between the Emesent Hovermap HF1 mobile laser scanner and the Faro Laser Scanner Focus3D X 330 terrestrial laser scanner

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Claes Gustafsson; [2023]
    Nyckelord :Terrestrial laser scanning; mobile laser scanning; simultaneous localization and mapping; underground mapping; Kiruna mine.;

    Sammanfattning : The mining industry has over the last few decades seen a drastic increase in the usage of laser scanning technologies as a way of creating 3D maps of the mines being exploited. Underground mapping in places such as mines has become more prevalent as the technology has progressed and made it easier to generate highly detailed point clouds faster. LÄS MER

  3. 2. Minimal Deformation Methods for Loop Closure

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Erik Tegler; [2021]
    Nyckelord :Mathematics and Statistics;

    Sammanfattning : This thesis proposes a method for how to find duplicated 3D points in a single Structure from Motion point cloud. Together with related articles, this forms a possible solution to the loop closure problem. The proposed method works by first selecting candidate pairs of 3D points by comparing BRIEF descriptors of all points. LÄS MER

  4. 3. Map Partition and Loop Closure in a Factor Graph Based SAM System

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Emil Relfsson; [2020]
    Nyckelord :SAM; Factor graph; Map partition; Smoothing and Mapping; SLAM;

    Sammanfattning : The graph-based formulation of the navigation problem is establishing itself as one of the standard ways to formulate the navigation problem within the sensor fusion community. It enables a convenient way to access information from previous positions which can be used to enhance the estimate of the current position. LÄS MER

  5. 4. Visual-LiDAR SLAM with loop closure

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yoshua Nava Chocron; [2019]
    Nyckelord :;

    Sammanfattning : State-of-the-art LIDAR odometry techniques are exceptionally precise. However, while they solve the localization problem, they perform mapping on-the-run, not being able to close loops, neither re-localize in previously visited environments. LÄS MER

  7. 5. Integrating membrane filtration forwater reuse in tissue mill

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ehsan Moslehi; [2018]
    Nyckelord :Membrane separation; Paper industry; Paper mill effluent; Water reuse ; Reverse Osmosis;

    Sammanfattning : Water is an essential and indispensable component is the pulp- and paper production industry.The increase in energy costs, stricter environmental regulations and water resource shortageshave caused a reduction of the water footprint in the industry as well as an increase in waterrecycling and water circuit closure.
