Autonomous flight at low altitude with vision-based collision avoidance and GPS-based path following
13 years 6 months ago
The ability to fly at low altitude while actively avoiding collisions with the terrain and other objects is a great challenge for small unmanned aircraft. This paper builds on top ...
