  1. 1. A Positioning System for Landing a UAV on a UGV in a GNSS-Denied Scenario

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Tim Wiik; [2022]
    Nyckelord :Sensor fusion; UAV; UGV; NIR-LED; Extended kalman filter; Unmanned Aerial Vehicle; Unmanned Ground Vehicle; Autonomous Landing; GNSS-denied Scenario;

    Sammanfattning : A system of an unmanned aerial vehicle (UAV) collaborating with an unmanned ground vehicle (UGV) for use in for example surveillance, reconnaissance, transport and target acquisition is studied. The project investigates the problem of estimating the relative position, velocity and orientation between the UAV and the UGV required to autonomously land the UAV on the UGV during movement.

  3. 2. Gait screening using a mobile phone application : horse asymmetry levels and usability of a mobile phone application for gait analysis, during a long format FEI eventing competition

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Anatomy, Physiology and Biochemistry

    Författare :Jonna Martinsson; [2022]
    Nyckelord :Gait analysis; motion asymmetry; performing horses; FEI eventing; Artificial intelligence; computer vision; kinematics; gait screening; mobile phone application;

    Sammanfattning : Orthopaedic disorders are the most common reason for unplanned rest in the performing horse population. Locomotor disorders which slowly build up to clear lameness might be avoidable with easy access objective motion measurement devices. LÄS MER

  4. 3. Automatic Calibration of Camera Parameters : A Steppingstone to Analysing Videos

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Wilma Hallén; [2022]
    Nyckelord :Smartphone; Video stabilisation; Calibration;

    Sammanfattning : The smartphone is commonly used for image and video capture. Due to the lightweight of the smartphone, small handshakes are noticeable in recorded videos. The image sensors in smartphones are typically CMOS, which introduces rolling shutter artefacts. Stabilisation is introduced to minimise the effects of the camera movement and artefacts. LÄS MER

  5. 4. Quantification and Detection of Motion Artifacts in Laser Speckle Contrast Imaging

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Dennis Amphan; [2022]
    Nyckelord :Laser speckle contrast imaging; Image registration; Motion artifacts; Detection;

    Sammanfattning : Laser speckle contrast imaging (LSCI) is a non-invasive method for assessment of microcirculatory blood flow. The technique is based on analysis of speckle patterns to build 2D maps of perfusion with high spatial and temporal resolution. LÄS MER

  7. 5. Noggrannhet inom projicerad förstärkt verklighet

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Richie Rizal; Raffi Bouyaji; [2022]
    Nyckelord :projected augmented reality; computer vision; augmented reality; depth-camera; projector; accuracy; pose detection; projicerad förstärkt verklighet; datorseende; förstärkt verklighet; djupkamera; projektor; noggrannhet; positionsuppskattning;

    Sammanfattning : Interaktiv projicerad förstärkt verklighet är ett delområde inom projicerad förstärktverklighet, där interaktiviteten handlar om att projicera virtuelldata på en entitet somär rörlig. Denna projektion kan åstadkommas genom att använda en kalibrerad projektor-djupkamerasystem som detekterar entitet med hjälp av datorseende. LÄS MER
