  1. 11. Learning with Synthetically Blocked Images for Sensor Blockage Detection

    Master-uppsats, Linköpings universitet/Datorseende

    Författare :Hoang Tran; [2022]
    Nyckelord :Machine learning; deep learning; neural networks; synthetic data; sensor blockage; domain adaptation;

    Sammanfattning : With the increasing demand for labeled data in machine learning for visual perception tasks, the interest in using synthetically generated data has grown. Due to the existence of a domain gap between synthetic and real data, strategies in domain adaptation are necessary to achieve high performance with models trained on synthetic or mixed data.

  3. 12. Gimbal stabilization of superzoom cameras

    Kandidat-uppsats, Lunds universitet/Industriell elektroteknik och automation

    Författare :Max Borglowe; [2022]
    Nyckelord :Image-stabilization; BLDC motor; Gimbal; IMU; FOC; Technology and Engineering;

    Sammanfattning : With today’s advancements in camera technology, image-stabilization is a crucial element for capturing sharp and steady images and video. Nowadays, cameras usually have built-in stabilizers that perform well in this task. In some cases, however, an additional stabilizer may be required to achieve optimal results. LÄS MER

  4. 13. Localization of Combat Aircraft at High Altitude using Visual Odometry

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Jenny Nilsson Boij; [2022]
    Nyckelord :Monocular Visual Odometry; Monocular SLAM; High Altitude; Combat Aircraft; X-Plane;

    Sammanfattning : Most of the navigation systems used in today’s aircraft rely on Global Navigation Satellite Systems (GNSS). However, GNSS is not fully reliable. For example, it can be jammed by attacks on the space or ground segments of the system or denied at inaccessible areas. LÄS MER

  5. 14. Autonomous Landing of an Unmanned Aerial Vehicle on an Unmanned Ground Vehicle using Model Predictive Control

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Emil Boström; Erik Börjesson; [2022]
    Nyckelord :Model predictive control; MPC; Unmanned aerial vehicle; UAV; Unmanned ground vehicle; UGV; Path planning; Vehicle dynamics; Autonomous systems; Autonomous landing; Quadcopter; Gazebo; ROS;

    Sammanfattning : The research on autonomous vehicles, and more specifically cooperation between autonomous vehicles, has become a prominent research field during the last cou- ple of decades. One example is the combination of an unmanned aerial vehicle (UAV) together with an unmanned ground vehicle (UGV). LÄS MER

  7. 15. Using Optical Flow to provide robustness for animage sensor based multiangulation positioning system

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Fredrik Anderson; [2022]
    Nyckelord :;

    Sammanfattning : The use of image sensors in positioning systems has increased significantly the last years, spanning from complex SLAM-systems to simpler triangulation based methods. In the latter case, occlusion of anchor points may render the triangulation unsolvable, and any practical implementation must address this problem. LÄS MER
