  1. 1. Local visual feature based localisation and mapping by mobile robots

    Författare :Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robotics; registration; localisation; SLAM; mapping; omnidirectional vision; 3D vision; appearance based; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This thesis addresses the problems of registration, localisation and simultaneous localisation and mapping (SLAM), relying particularly on local visual features extracted from camera images. These fundamental problems in mobile robot navigation are tightly coupled. LÄS MER

  3. 2. Vision-based Localization and Attitude Estimation Methods in Natural Environments

    Författare :Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Joni Kämäräinen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Over the last decade, the usage of unmanned systems such as Unmanned Aerial Vehicles (UAVs), Unmanned Surface Vessels (USVs) and Unmanned Ground Vehicles (UGVs) has increased drastically, and there is still a rapid growth. Today, unmanned systems are being deployed in many daily operations, e.g. LÄS MER

  4. 3. Camera Modelling and Calibration with Machine Vision Applications

    Författare :Anders Ryberg; Bengt Lennartson; Anna-Karin Christiansson; Anders Heyden; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Camera model; Camera calibration; Fisheye camera; Catadioptric camera; Stereo vision; Other technology; Övriga teknikvetenskaper; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Camera modelling and calibration are important parts of machine vision. They can be used for calculating geometric information from images. A camera model is a mathematical projection between a 3D object space and a 2D image. LÄS MER

  5. 4. Global Pose Estimation from Aerial Images : Registration with Elevation Models

    Författare :Bertil Grelsson; Michael Felsberg; Per-Erik Forssén; Kalle Åström; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Over the last decade, the use of unmanned aerial vehicles (UAVs) has increased drastically. Originally, the use of these aircraft was mainly military, but today many civil applications have emerged. LÄS MER

  7. 5. Vision-Based Perception for Localization of Autonomous Agricultural Robots

    Författare :Stefan Ericson; Björn Åstrand; Gert Kootstra; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production and Automation Engineering; Produktion och automatiseringsteknik; INF201 Virtual Production Development; INF201 Virtual Production Development;

    Sammanfattning : In this thesis Stefan investigates how cameras can be used for localization of an agricultural mobile robot. He focuses on relative measurement that can be used to determine where a weeding tool is operating relative a weed detection sensor. LÄS MER
