  1. 11. Vision-based Human Detection from Mobile Machinery in Industrial Environments

    Författare :Rafael Mosberger; Achim J. Lilienthal; Henrik Andreasson; Jürgen Gall; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Industrial Safety; Mobile Machinery; Human Detection; Computer Vision; Machine Learning; Infrared Vision; High-visibility Clothing; Reflective Markers; Datavetenskap; Computer Science;

    Sammanfattning : The problem addressed in this thesis is the detection, localisation and tracking of human workers from mobile industrial machinery using a customised vision system developed at Örebro University. Coined the RefleX Vision System, its hardware configuration and computer vision algorithms were specifically designed for real-world industrial scenarios where workers are required to wear protective high-visibility garments with retro-reflective markers.

  4. 13. Bird Vision: Spatial acuity and colour discrimination in bright and dim light

    Författare :Olle Lind; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal vision; Visual ecology; Colour vision; Spatial acuity; Spatial contrast sensitivity; Dim light; Visual modelling; Behavioural experiments; Birds; Psittaciformes;

    Sammanfattning : Birds use vision to guide navigation, foraging and mate choice, and studies of the limitations in bird visual perception are most helpful for the understanding of bird ecology. Here, I present four studies of bird vision in bright and dim light. LÄS MER

  5. 14. Den unge Manfred Björkquist : Hur en vision av kristendomens möte med kultur och samhälle växer fram

    Författare :Torbjörn Aronson; Oloph Bexell; Kjell Blückert; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; vision; »folk church»; confessional Lutheranism; Pietism; consensus; civil society; Christian Student Association; nationalism; Young Church movement; Church history; Kyrkohistoria;

    Sammanfattning : This thesis is a biographical study of Manfred Björkquist’s early life and addresses questions concerning the development of his vision of Christianity, culture and soci-ety. A comparison is also made between Björkquist’s vision and the classical typol-ogy of H. Richard Niebuhr. LÄS MER

  7. 15. On Robot Control using Range Sensors : with Special Reference to Active Uncertainty Reduction

    Författare :Bernt Nilsson; Aarne Halme; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Robot Gripping and Docking; Gripper-Object Feedback; Non-contact Sensing; Laser Ranging; Flexible Arm; Mobile Robot; Probing; Dual Control; LQG-Feedback;

    Sammanfattning : This thesis addresses the problem of positioning robots relative to objects in the surrounding work space. The object's position and orientation (posture) are measured using a non-contact sensor on-board the robot. For gripping/docking tasks the goal posture is specified relative to the object and not in a fixed coordinate system of the robot. LÄS MER
