  1. 1. Long-Term Localization for Self-Driving Cars

    Författare :Erik Stenborg; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sequential semantic localization; self-driving; localization;

    Sammanfattning : Long-term localization is hard due to changing conditions, while relative localization within time sequences is much easier. To achieve long-term localization in a sequential setting, such as, for self-driving cars, relative localization should be used to the fullest extent, whenever possible. LÄS MER

  3. 2. Analysis of Retroreflection and other Properties of Road Signs

    Författare :Roxan Saleh; Hasan Fleyeh; Darko Babić; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Road traffic signs; retroreflective sheeting material; night-time visibility; supervised machine learning; principal component analysis; prediction; linear regression;

    Sammanfattning : Road traffic signs provide regulatory, warning, guidance, and other important information to road users to prevent hazards and road accidents. Therefore, the traffic signs must be detectable, legible, and visible both in day and nighttime to fulfill their purpose. The nighttime visibility is critical to safe driving on the roads at night.

  4. 3. Towards Robust Visual Localization in Challenging Conditions

    Författare :Carl Toft; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; benchmark; long-term localization; self-driving cars; camera pose estimation; Visual localization; autonomous vehicles;

    Sammanfattning : Visual localization is a fundamental problem in computer vision, with a multitude of applications in robotics, augmented reality and structure-from-motion. The basic problem is to, based on one or more images, figure out the position and orientation of the camera which captured these images relative to some model of the environment. LÄS MER

  7. 5. Impacts of urbanisation on birds : Disentangling the effects of multiple pollutants on avian behaviour and physiology

    Författare :Ann-Kathrin Ziegler; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; artificial light at night; ALAN; antioxidants; great tit; light pollution; LPS; multi-stressor; noise pollution; tropospheric ozone; urbanisation; zebra finch;

    Sammanfattning : Anthropogenic pollution is a pervasive feature of urbanisation, reaching into ecosystems worldwide and posing novel challenges to wildlife. Not surprisingly, differences in behaviour, and physiology, have been found between urban and rural populations. LÄS MER
