  4. 3. Drone Detection using Deep Learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Yating Liu; [2023]
    Nyckelord :Drone Detection; Real-time Tracking; Deep Learning; Computer Vision; Small Object Detection; YOLO; Drönardetektering; Realtidsspårning; Deep Learning; Computer Vision; Small Object Detection; YOLO;

    Sammanfattning : Drone intrusions have been reported more frequently these years as drones become more accessible in the market. The abuse of drones puts threats to public and individual safety and privacy. Traditional anti-drone systems use radio-frequency sensors widely to get the position of drones. LÄS MER

  5. 4. Online Camera-IMU Calibration

    Master-uppsats, Linköpings universitet/Datorseende; Linköpings universitet/Tekniska fakulteten

    Författare :Arvid Karlhede; [2022]
    Nyckelord :Computer vision; Online calibration; Camera; IMU; Euroc;

    Sammanfattning : This master thesis project was done together with Saab Dynamics in Linköping the spring of 2022 and aims to perform an online IMU-camera calibration using an AprilTag board. Experiments are conducted on two different types of datasets, the public dataset Euroc and internal datasets from Saab. LÄS MER

  7. 5. Modeling and Control of a PMSM Operating in Low Speeds

    Master-uppsats, Linköpings universitet/Fordonssystem
