7. 5. Drones for Sea Rescue: Lab and Field Experiments on Camera Gimbal Control

   Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

   Författare :Alexander Sandström; [2023]
   Nyckelord :Drones; Search and Rescue; Unmanned Aerial Vehicle; UAV; gimbal; camera control; ArduPilot; Quality of Experience; QoE; Technology and Engineering;

   Sammanfattning : The objective of this thesis has been to improve the camera controls of a fixed-wing drone to be used in maritime search-and-rescue operations by the Swedish Sea Rescue Society (SSRS). A gimbal control interface (GCI) has been implemented that displays the video feed of the drone camera while taking control inputs from a joystick that moves its view in real-time. LÄS MER
