   Sammanfattning : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. LÄS MER

3. 17. One Image, Many Insights: A Synergistic Approach Towards Enabling Autonomous Visual Inspection

   Författare :Vignesh Kottayam Viswanathan; George Nikolakopoulos; Dimitrios Kanoulas; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Unified autonomy; aerial robotics; space robotics; Robotics and Artificial Intelligence; Robotik och artificiell intelligens;

   Sammanfattning : Visual inspection in autonomous robotics is a task in which autonomous agents are required to gather visual information of objects of interest, in a manner that ensures safety, efficiency and comprehensive coverage. It is, therefore, crucial for identifying key landmarks, detecting cracks or defects, or reconstructing the observed object for detailed analysis. LÄS MER

4. 18. Coordination of Multi-Agent Systems: Predictive and Vision-based Control for Aerial and Space Robotics

   Författare :Pedro Roque; Dimos V. Dimarogonas; Mikael Johansson; Soon-Jo Chung; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Aerial and space autonomous systems are safety-critical systems that need to operate safely and reliably for long periods of time. Their applications range from autonomous inspection of complex and sensitive structures, to surveillance and transportation of sensitive payloads. LÄS MER

5. 19. Computer Vision for Traffic Surveillance Systems : Methods and Applications

   Författare :Saleh Javadi; Mattias Dahl; Michael Cree; Blekinge Tekniska Högskola; []
