Abstract
A method of controlling flight of an unmanned aerial vehicle (UAV) includes collecting, while the UAV traverses a flight path, a first set of images corresponding to different fields of view of an environment around the UAV using multiple image capture devices. Each of the multiple image capture devices has one of the different fields of view. The method further includes extracting a first set of feature points from the first set of images, controlling the UAV to traverse a return path, and while the UAV traverses the return path, collecting a second set of images corresponding to the different fields of view using the multiple image capture devices and comparing the first set of feature points with a second set of feature points extracted from the second set of images.
