    Sammanfattning : Indoor positioning systems (IPS) has seen an increase in demand because of the needto locate users in environments where Global Navigation Satellite Systems (GNSS) lacksaccuracy. The current way of implementing an IPS is often tedious and time consuming. LÄS MER

  4. 3. Automatic Room-Blueprint Extraction using SfM

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joakim Ericson; Filip Jardby; [2020]
    Nyckelord :Technology and Engineering;

    Sammanfattning : In this thesis the possibility of automatically generating a blueprint of an indoor area, for example a grocery store, using a smartphone camera and images from existing analytic or surveillance cameras was examined. The method used for the transition between 2D camera images and 3D reconstruction was Structure from Motion. LÄS MER
