Visual terrain classification by flying robots [PDF]

2012 IEEE International Conference on Robotics and Automation, 2012
In this paper we investigate the effectiveness of SURF features for visual terrain classification for outdoor flying robots. A quadrocopter fitted with a single camera is flown over different terrains to take images of the ground below. Each image is divided into a grid and SURF features are calculated at grid intersections.
