  1. 1. Movement Estimation with SLAM through Multimodal Sensor Fusion

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Jimmy Cedervall Lamin; [2024]
    Nyckelord :slam; discrete-slam; continuous-slam; synchronous; asynchronous; computer vision; BRISK; opencv; ceres; visual; inertial; sensor fusion; multimodal; Simultaneous Localization and Mapping; time offset; pose estimation; quaternions; movement estimation;

    Sammanfattning : In the field of robotics and self-navigation, Simultaneous Localization and Mapping (SLAM) is a technique crucial for estimating poses while concurrently creating a map of the environment. Robotics applications often rely on various sensors for pose estimation, including cameras, inertial measurement units (IMUs), and more. LÄS MER

  3. 2. Slice regular functions (Gentili er al., 2022) : Quaternions

    Master-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Mitra Fathian Pourkondori; [2023]
    Nyckelord :slice regular; quaternions;

    Sammanfattning : This thesis constitutes a comprehensive study of the fundamental properties of an analytic function theory over quaternions, which is known as slice regularity, as introduced in Gentili et al. (Gentili et al., 2022). In 2006, an approach to analysis over quaternions was introduced by G. LÄS MER

  4. 3. Development of a Level-0 Geoprocessing Platform for a Multispectral Remote Sensing Payload

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sergio Santiago Bernabeu Peñalba; [2022]
    Nyckelord :Infrared imagery; VIS; NIR; LWIR; geoprocessor; geolocation; quaternions; Aistech Space; image processing; ORB; RANSAC; Sentinel; Landsat; Infraröda bilder; VIS; NIR; LWIR; geoprocessor; geolokalisering; kvarternioner; Aistech Space; bildbehandling; ORB; RANSAC; Sentinel; Landsat;

    Sammanfattning : This thesis presented an overview of the development of a geolocating algorithm as part of a geoprocessor for raw satellite imagery. This algorithm was devised for and limited by the specifications of a state-of-the-art multispectral telescope designed by Aistech Space, hosted onboard the Guardian spacecraft, which will observe Earth through the visible, near infrared, and thermal infrared bands of the electromagnetic spectrum.

  5. 4. Clifford Algebra - A Unified Language for Geometric Operations

    Kandidat-uppsats, KTH/Fysik

    Författare :Leo Gordin; Henrik Taro Hansson; [2022]
    Nyckelord :clifford algebra; geometric algebra; algebra; tensors;

    Sammanfattning : In this paper the Clifford Algebra is introduced and proposed as analternative to Gibbs' vector algebra as a unifying language for geometricoperations on vectors. Firstly, the algebra is constructed using a quotientof the tensor algebra and then its most important properties are proved,including how it enables division between vectors and how it is connected tothe exterior algebra.

  7. 5. Quaternionic Analysis

    Kandidat-uppsats, Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Författare :Mitra Fathian Pourkondori; [2022]
    Nyckelord :Quaternion;

    Sammanfattning : In this thesis, we study Quaternionic Analysis, which is the most natural and close generalization of complex analysis. Quaternion Analysis conserves many of its important features by key reference A. Sudbery. LÄS MER
