  1. 21. Pose Estimation and Calibration Algorithms for Vision and Inertial Sensors

    Författare :Jeroen Diederik Hol; Fredrik Gustafsson; Thomas Schön; Patric Jensfelt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pose estimation; Sensor fusion; Computer vision; Inertial navigation; Calibration; Automatic control; Reglerteknik;

    Sammanfattning : This thesis deals with estimating position and orientation in real-time, using measurements from vision and inertial sensors. A system has been developed to solve this problem in unprepared environments, assuming that a map or scene model is available. LÄS MER

  3. 22. Sensor Fusion and Calibration of Inertial Sensors, Vision, Ultra-Wideband and GPS

    Författare :Jeroen D. Hol; Thomas Schön; Fredrik Gustafsson; Bo Bernhardsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor fusion; calibration; inertial sensors; vision; UWB; GPS; Automatic control; Reglerteknik;

    Sammanfattning : The usage of inertial sensors has traditionally been confined primarily to the aviation and marine industry due to their associated cost and bulkiness. During the last decade, however, inertial sensors have undergone a rather dramatic reduction in both size and cost with the introduction of MEMS technology. LÄS MER

  4. 23. Human Postural Sway Modeling and Balance Impairment Detection

    Författare :Hedyeh Jafari; Thomas Gustafsson; George Nikolakopoulos; Fredrik Öhberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Reglerteknik;

    Sammanfattning : Falls, Fear of falling (FoF), and low balance confidence pose significant threats to health and independence among older people. This thesis aims to study humans’ postural and balance mechanisms, from analyzing the effect of multisensory inputs on balance performance and balance-related concerns to modeling the postural sway through physical dynamics and data-driven approaches.

  5. 24. Selection of Decentralized Control Configuration for Uncertain Systems

    Författare :Ali Kadhim; Wolfgang Birk; Thomas Gustafsson; Miguel Castaño Arranz; Torsten Wik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Industrial processes nowadays involve hundreds or more of variables to be maintained within predefined ranges to achieve the production demands. However, the lack of accurate models and practical tools to design controllers for such large processes motivate the engineers/practitioners to break the processes down into smaller subsystems and applying decentralized controllers.

  7. 25. Probabilistic modeling for positioning applications using inertial sensors

    Författare :Manon Kok; Thomas Schön; Fredrik Gustafsson; Gabriele Bleser; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In this thesis, we consider the problem of estimating position and orientation (6D pose) using inertial sensors (accelerometers and gyroscopes). Inertial sensors provide information about the change in position and orientation at high sampling rates. LÄS MER
