  2. 1. Position Sensitive Detectors : Device Technology and Applications in Spectroscopy

    Author : Henrik Andersson; Hans-Erik Nilsson; Göran Thungström; Jan Linnros; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Position sensitive detectors; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis deals with the development, processing and characterization of position sensitive detectors and, in addition, to the development of compact and cost effective spectrometers. Position sensitive detectors are used to measure, with great accuracy and speed, the position of a light spot incident on the surface. READ MORE

  4. 2. Pose Estimation and Calibration Algorithms for Vision and Inertial Sensors

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

    Abstract : 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. READ MORE

  5. 3. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

    Author : Yuriy Reshetyuk; Lars E. Sjöberg; Stig-Göran Mårtensson; KTH; []
    Keywords : terrestrial laser scanning; error sources; calibration; coordinate precision accuracy;

    Abstract : This thesis has two aims. The first one is the investigation and analysis of the errors occurring in the measurements with pulsed time-of-flight (TOF) terrestrial laser scanners (TLS). A good understanding of the error sources and the relationships between them is necessary to secure the data accuracy. READ MORE

  6. 4. Sensor Fusion and Calibration of Inertial Sensors, Vision, Ultra-Wideband and GPS

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

    Abstract : 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. READ MORE

  7. 5. Inertial Sensor Arrays : Sensor Fusion and Calibration

    Author : Håkan Carlsson; Joakim Jaldén; Thomas Seel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Motion estimation using inertial sensors is today used in a wide range of applications, from aircraft navigation to inflatable bicycle helmets. The accuracy with which the motion can be estimated using inertial sensors depends on how large the measurement errors are. READ MORE
