1. 6. 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. 7. Investigation and calibration of pulsed time-of-flight terrestrial laser scanners

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

   Sammanfattning : 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. LÄS MER

4. 8. 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

5. 9. Studies in Robotic Vision, Optical Illusions and Nonlinear Diffusion Filtering

   Författare :Henrik Malm; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; hand-eye calibration; camera calibration; nonlinear diffusion filtering; robotic vision; optical illusions; Mathematics; Matematik;

   Sammanfattning : This thesis is divided into three parts, which all deal with computational analysis and processing of images. However, the settings are quite diverse.They range from robotic camera sensors, over human perception, to physical measurement setups. LÄS MER

7. 10. CONTRIBUTION TO QUANTITATIVE MICROWAVE IMAGING TECHNIQUES FOR BIOMEDICAL APPLICATIONS

   Författare :Tommy Henriksson; Ylva Bäcklund; Magnus Otterskog; Hans Sköld; Jean-Charles Bolomey; Nadine Joachimowicz; Alain Joisel; Paul M. Meaney; Christian Pichot; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantitative Microwave Imaging. Inverse Problems; Nonliear Inverse Scattering; Diffraction Tomography; Breast Tumor Detection; Biomedical Imaging; Mammography; Calibration; Modeling; Planar 2.45 GHz Microwave Camera; Robot-based flexible multi-frequency data acquisition; Electrophysics; Elektrofysik; Elektronik; Electronics;

   Sammanfattning : This dissertation presents a contribution to quantitative microwave imaging for breast tumor detection. The study made in the frame of a joint supervision Ph.D. thesis between University Paris-SUD 11 (France) and Mälardalen University (Sweden), has been conducted through two experimental microwave imaging setups, the existing 2.
