  1. 11. The three-dimensional normal-distributions transform : an efficient representation for registration, surface analysis, and loop detection

    Författare :Martin Magnusson; Achim Lilienthal; Wolfram Burgard; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NDT; 3D sensing; surface representation; registration; loop detection; surface analysis; mobile robotics; localisation; mapping; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : This dissertation is concerned with three-dimensional (3D) sensing and 3D scan representation. Three-dimensional records are important tools in several disciplines; such as medical imaging, archaeology, and mobile robotics. LÄS MER

  3. 12. Development of a Mobile Tomographic Gamma Camera Based on Ectomography - Cardiotom

    Författare :Mikael Persson; KTH; []
    Nyckelord :acute studies; myocardial infarction; scintigraphy; mobile gamma camera; tomography;

    Sammanfattning : Successful treatment of myocardial infarction requires anearly and accurate diagnosis. Recent studies have shown thatacute myocardial scintigraphy has a high predictive value forprognosis of myocardial events. Three dimensional (3D)perfusion data obtained with SPECT are however very rare in theemergency department (ED). LÄS MER

  4. 13. Navigation and Mapping for Aerial Vehicles Based on Inertial and Imaging Sensors

    Författare :Zoran Sjanic; Fredrik Gustafsson; Thomas Schön; Fulvio Gini; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Small and medium sized Unmanned Aerial Vehicles (UAV) are today used in military missions, and will in the future find many new application areas such as surveillance for exploration and security. To enable all these foreseen applications, the UAV's have to be cheap and of low weight, which restrict the sensors that can be used for navigation and surveillance. LÄS MER
