  1. 1. Inertial Navigation and Mapping for Autonomous Vehicles

    Författare :Martin Skoglund; Fredrik Gustafsson; Thomas Schön; Tim Bailey; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SLAM; Inertial Navigation; Filtering; Smoothing; Cameras; Optimisation; Autonomous;

    Sammanfattning : Navigation and mapping in unknown environments is an important building block for increased autonomy of unmanned vehicles, since external positioning systems can be susceptible to interference or simply being inaccessible. Navigation and mapping require signal processing of vehicle sensor data to estimate motion relative to the surrounding environment and to simultaneously estimate various properties of the surrounding environment.

  3. 2. Visual Inertial Navigation and Calibration

    Författare :Martin A. Skoglund; Fredrik Gustafsson; Thomas Schön; Henk Luinge; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Processing and interpretation of visual content is essential to many systems and applications. This requires knowledge of how the content is sensed and also what is sensed. Such knowledge is captured in models which, depending on the application, can be very advanced or simple. LÄS MER

  4. 3. Adaptations for nocturnal vision in insect apposition eyes

    Författare :Birgit Greiner; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; temporal and spatial summation; optical and neural adaptations; theoretical modelling.; Djurs anatomi och morfologi; Zoologi; dim light; vision; landmark navigation; nocturnal bees and wasps; Zoology; Animal anatomy; animal morphology;

    Sammanfattning : Due to our own preference for bright light, we tend to forget that many insects are active in very dim light. The reasons for nocturnal activity are most easily seen in tropical areas of the world, where animals face severe competition for food and nocturnal insects are able to forage in a climate of reduced competition and predation.

  5. 4. On Landmark Densities in Minimum-Uncertainty Motion Planning

    Författare :Jonas Nordlöf; Daniel Axehill; Gustaf Hendeby; Patric Jensfelt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Accurate self-positioning of autonomous mobile platforms is important when performing tasks such as target tracking, reconnaissance and resupply missions. Without access to an existing positioning infrastructure, such as Global Navigation Satellite Systems (GNSS), the platform instead needs to rely on its own sensors to obtain an accurate position estimate.
