  1. 1. Skyline Delineation for Localization in Occluded Environments : Improved Skyline Delineation using Environmental Context from Deep Learning-based Semantic Segmentation

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Kyle William Coble; [2023]
    Keywords : Skyline delineation; Skyline detection; Semantic segmentation; Terrain based navigation; Digital elevation models; Uncrewed surface vessel; Planetary exploration robots; Horisont avgränsning; Horisont upptäckt; Semantisk segmentering; Terrängbaserad navigering; Digitala höjdmodeller; Obemannat ytfartyg; Planetariska utforskningsrobotar;

    Abstract : This thesis addresses the problem of improving the delineation of skylines, also referred to as skyline detection, in occluded and challenging environments where existing skyline delineation methods may struggle or fail. Delineated skylines can be used in monocular camera localization methods by comparing delineated skylines to digital elevation model data to estimate a position based on known terrain. READ MORE

    Abstract : Can an outward facing camera on a bus, be used to recognize its location in GPS denied environment? Observit, provides cloud-based mobile surveillance services for bus operators using IP cameras with wireless connectivity. With the continuous gathering of video information, it opens up new possibilities for additional services. READ MORE

  4. 3. Deep Feature UAV Localization in Urban Areas and Agricultural Fields and Forests

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Markus Mäkelä; [2021]
    Keywords : UAV Localization; Deep Learning; Lucas-Kanade; Absolute Localization; Visual localization; UAV lokalisering; Djupinlärning; Lucas-Kanade; Absolut lokalisering; Visuell lokalisering;

    Abstract : The reliance on GPS for Unmanned Aerial Vehicle (UAV) localization limits the areas of application to places with a stable GPS signal. The emergence of deep learning in computer vision has made deep learning methods for visual UAV navigation a promising candidate for autonomous GPS denied localization. READ MORE

  5. 4. The Effects of Sensor Fusion on Localisation in a Sparse, Outdoor Environment

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Kayla Kearns; [2020]
    Keywords : ;

    Abstract : This thesis compares the results of a localisation algorithm for a mobile robot in both a sparse and a densely featured environment whilst varying key parameters. The software and hardware required to enable the mobile robot to localise itself in the sparsely featured, GPS-denied, outdoor environment is described. READ MORE
