  1. 1. Camera Modelling and Calibration with Machine Vision Applications

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

    Abstract : 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. READ MORE

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

    Author : Henrik Andreasson; Achim Lilienthal; Jim Little; Örebro universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  4. 4. Vision-Based Perception for Localization of Autonomous Agricultural Robots

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

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE
