  1. 1. Automation of forest road inventory using computer vision and machine learning

    University essay from Umeå universitet/Institutionen för fysik

    Author : Jacques de Flon; [2023]
    Keywords : Computer vision; Machine Learning; Image recognition; forestry; road inventory; pothole; gravel road;

    Abstract : There are around 300, 000 kilometer of gravel roads throughout the Swedish countryside, used every day by common people and companies. These roads face constant wear due to harsh weather as well as from heavy traffic, and thus, regular maintenance is required to keep up the road standard. READ MORE

  3. 2. Identification of shape errors in a parabolic solar collector : An improvement to the analysing algorithms examining the solar collector from optical measurements

    University essay from Umeå universitet/Institutionen för fysik

    Author : Malin Gelfgren; [2023]
    Keywords : ;

    Abstract : Increasing global warming with droughts, forest fires and melting polar ice has forced the world to speed up the transition from fossil fuel to fossil free energy. A big part of it is the use of solar energy. To obtain solar thermal energy, different sorts of solar collectors have been developed. READ MORE

  4. 3. A Machine Learning Approach for Comprehending Cosmic Expansion

    University essay from KTH/Fysik

    Author : Ludvig Doeser; [2021]
    Keywords : Cosmology; Cosmic expansion; Galaxy Images; Machine learning; Kosmologi; kosmisk expansion; galaxbilder; maskininlärning;

    Abstract : This thesis aims at using novel machine learning techniques to test the dynamics of the Universe via the cosmological redshift-distance test. Currently, one of the most outstanding questions in cosmology is the physical cause of the accelerating cosmic expansion observed with supernovae. READ MORE

  5. 4. Indoor triangulation system using vision sensors

    University essay from Uppsala universitet/Signaler och system

    Author : Torun Nicander; [2020]
    Keywords : positioning; triangulation; vision sensor; computer vision;

    Abstract : This thesis aims to investigate a triangulation system for indoor positioning in two dimensions (2D). The system was implemented using three Pixy2 vision sensors placed on a straight baseline. A Pixy2 consists of a camera lens and an image sensor (Aptina MT9M114) as well as a microcontroller (NXP LPC4330), and other components. READ MORE

  6. 5. COMPARISON OF THE GRAPH-OPTIMIZATION FRAMEWORKS G2O AND SBA

    University essay from Mälardalens högskola/Akademin för innovation, design och teknik

    Author : Henning Victorin; [2016]
    Keywords : SLAM; g2o; SBA; graph-optimization; new college; venice; mono-slam; VSLAM;

    Abstract : This thesis starts with an introduction to Simulataneous Localization and Mapping (SLAM) and more background on Visual SLAM (VSLAM). The goal of VSLAM is to map the world with a camera, and at the same time localize the camera in that world. One important step is to optimize the acquired map, which can be done in several different ways. READ MORE
