  1. 1. Charcoal Kiln Detection from LiDAR-derived Digital Elevation Models Combining Morphometric Classification and Image Processing Techniques

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Vaidutis Zutautas; [2017]
    Keywords : charcoal kilns; automatic feature extraction; LiDAR; morphometric classification; Hough Circle transfer; medžio anglies krosnis; automatinis objektų išgavimas; LiDAR; morformetrinė klasifikacija; Hough apskritimo transformacija; kolbottnar efter resmila; automatisk funktion extraktion; LiDAR; morfometrisk klassificering; Hough Circle överföring;

    Abstract : This paper describes a unique method for the semi-automatic detection of historic charcoal production sites in LiDAR-derived digital elevation models. Intensified iron production in the early 17th century has remarkably influenced ways of how the land in Sweden was managed. READ MORE

  2. 2. Reconstruction of trees from 3D point clouds

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : Martin Stålberg; [2017]
    Keywords : Bayes; Bayesian inference; point cloud; pointcloud; 3D; tree; trees; reconstruction; Matlab; Povray; Arbaro; model; LIDAR; Hough transform; cylinder; geometry; heuristic; Australia; Australian Centre for Field Robotics; spherical grid; icosahedron; likelihood; intersection; artificial data; color encoded; depth map; coordinate map; ray tracing;

    Abstract : The geometrical structure of a tree can consist of thousands, even millions, of branches, twigs and leaves in complex arrangements. The structure contains a lot of useful information and can be used for example to assess a tree's health or calculate parameters such as total wood volume or branch size distribution. READ MORE

  3. 3. Terrain sensor for semi active suspension in CV90

    University essay from Luleå tekniska universitet/Datavetenskap

    Author : Fredrik Nordin; [2017]
    Keywords : terrain sensor; cv90; slam; visual odometry; kinect; suspension; lidar; flir; lwir;

    Abstract : The combat vehicle, CV90 has a semi-active hydraulic suspension system which uses inertial measurements for regulation to improve accessibility. To improve performance further measurements of future terrain can be used to, for example, prepare for impacts. READ MORE

  4. 4. Backpack-based inertial navigation and LiDAR mapping in forest environments

    University essay from Umeå universitet/Institutionen för fysik

    Author : Tjernqvist Mattias; [2017]
    Keywords : lidar; gnss; ins; mls; forest;

    Abstract : Creating 3D models of our surrounding world has seen a rapid increase in research and development over the last few years. A common method is to use laser scanners. Mapping is done either by ground based systems or airborne systems. READ MORE

  5. 5. Dynamics of a retreating ice sheet : a LiDAR study in Värmland, SW Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Alastair Goodship; [2017]
    Keywords : LiDAR; SIS; retreat; deglacial; DEM; geomorphology; Värmland; Earth and Environmental Sciences;

    Abstract : Värmland in south central Sweden lies across the established zone of aquatic-terrestrial transition of the Scandinavian Ice Sheet margin during its rapid final retreat following the Younger Dryas. Recently acquired LiDAR data across Värmland allows more highly detailed observation and analysis of glacial landforms formed during this stage than has previously been possible. READ MORE
