Visual Marker Detection In The Presence Of Colored Noise for Unmanned Aerial Vehicles
(Georgia Institute of Technology, 2010-04)
This paper develops a vision-based algorithm to detect a visual marker in real time and in the presence of excessive colored noise for Unmanned Aerial Vehicles. After using various image analysis techniques, including ...
Guidance, Navigation, Control, and Operator Interfaces for Small Rapid Response Unmanned Helicopters
(Georgia Institute of Technology, 2008-04)
This paper focuses on the development of small rapid response reconnaissance unmanned helicopters (1 to 3 kg, electric), for use by the military in urban areas and by civilian first responders, in terms of system ...
Flight Results of Autonomous Fixed-Wing UAV Transitions to and from Stationary Hover
(Georgia Institute of Technology, 2006-08)
Fixed-wing unmanned aerial vehicles (UAVs) with the ability to hover have significant potential for applications in urban or other constrained environments where the combination of fast speed, endurance, and stable ...
Vision-Aided Inertial Navigation for Flight Control
(Georgia Institute of Technology, 2005-09)
Many onboard navigation systems use the Global Positioning System to bound the errors that result from integrating inertial sensors over time. Global Positioning System information, however, is not always accessible since ...
Flight-Test Results of Autonomous Airplane Transitions Between Steady-Level and Hovering Flight
(Georgia Institute of Technology, 2008-03)
Linear systems can be used to adequately model and control an aircraft in either ideal steady-level flight or in ideal hovering flight. However, constructing a single unified system capable of adequately modeling or ...
Methods for Localization and Mapping Using Vision and Inertial Sensors
(Georgia Institute of Technology, 2008-08)
The problems of vision-based localization and mapping are currently highly active areas of research for aerial systems. With a wealth of information available in each image, vision sensors allow vehicles to gather data ...
