JATAYU: A Stereo Vision–Based UAV for Autonomous Navigation and Human Following in GPS-Denied EnvironmentsBy Cecilia Dinesh, Anas Fodkar, Amey Shelar, Tushar Nandy, Nilamabri G Narkar
Abstract: Traditional unmanned aerial vehicle (UAV) systems primarily rely on Global Positioning System (GPS)-based navigation and conventional computer vision techniques. However, these approaches face significant challenges in GPS-denied environments, such as dense urban areas, indoor spaces, and disaster-affected regions where GPS signals may be weak, unavailable, or unreliable. In addition, limitations in real-time processing, object detection accuracy, and environmental perception can reduce UAV effectiveness in dynamic and unpredictable situations. This paper …
