1. Self-calibration and direct georeferencing in terrestrial laser scanning
Sammanfattning : An important step in data processing from terrestrial laser scanning (TLS) is georeferencing, i.e. transformation of the scanner data (point clouds) into a real world coordinate system, which is important for their integration with other geospatial data. LÄS MER
2. Localization using Distance Geometry : Minimal Solvers and Robust Methods for Sensor Network Self-Calibration
Sammanfattning : In this thesis, we focus on the problem of estimating receiver and sender node positions given some form of distance measurements between them. This kind of localization problem has several applications, e.g. LÄS MER
3. Development of ultra-precision tools for metrology and lithography of large area photomasks and high definition displays
Sammanfattning : Large area flat displays are nowadays considered being a commodity. After the era of bulky CRT TV technology, LCD and OLED have taken over as the most prevalent technologies for high quality image display devices. LÄS MER
4. Computer Vision without Vision : Methods and Applications of Radio and Audio Based SLAM
Sammanfattning : The central problem of this thesis is estimating receiver-sender node positions from measured receiver-sender distances or equivalent measurements. This problem arises in many applications such as microphone array calibration, radio antenna array calibration, mapping and positioning using ultra-wideband and mapping and positioning using round-trip-time measurements between mobile phones and Wi-Fi-units. LÄS MER
5. Mapping and Merging Using Sound and Vision : Automatic Calibration and Map Fusion with Statistical Deformations
Sammanfattning : Over the last couple of years both cameras, audio and radio sensors have become cheaper and more common in our everyday lives. Such sensors can be used to create maps of where the sensors are positioned and the appearance of the surroundings. LÄS MER
