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

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

  4. 2. Efficient Remote Gas Inspection with an Autonomous Mobile Robot

    Author : Muhammad Asif Arain; Achim Lilienthal; Erik Schaffernicht; Victor Hernandez Bennetts; Marcello Cirillo; Marco Trincavelli; Pedro Lima; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; environmental monitoring; measurement planning; remote gas sensing; mobile robot olfaction; service robots;

    Abstract : Human-caused greenhouse gas emissions are one of the major sources of global warming, which is threatening to reach a tipping point. Inspection systems that can provide direct information about critical factors causing global warming, such as systems for gas detection and location of gas sources, are urgently needed to analyze the fugitive emissions and take necessary actions.

  5. 3. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning

    Author : Sahar Asadi; Achim Lilienthal; Amy Loutfi; Dominque Martinez; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

    Abstract : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. READ MORE

  6. 4. Truncated Signed Distance Fields Applied To Robotics

    Author : Daniel Ricão Canelhas; Achim Lilienthal; Todor Stoyanov; Giorgio Grisetti; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D mapping; pose estimation; feature detection; shape description; compression; unsupervised learning; Datavetenskap; Computer Science;

    Abstract : This thesis is concerned with topics related to dense mapping of large scale three-dimensional spaces. In particular, the motivating scenario of this work is one in which a mobile robot with limited computational resources explores an unknown environment using a depth-camera. READ MORE

  7. 5. People tracking by mobile robots using thermal and colour vision

    Author : Grzegorz Cielniak; Tom Duckett; Achim Lilienthal; Ben Kröse; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Abstract : This thesis addresses the problem of people detection and tracking by mobile robots in indoor environments. A system that can detect and recognise people is an essential part of any mobile robot that is designed to operate in populated environments. READ MORE
