Abstract: Described is a method that involves operating an unmanned aerial vehicle (UAV) to begin a flight, where the UAV relies on a navigation system to navigate to a destination. During the flight, the method involves operating a camera to capture images of the UAV's environment, and analyzing the images to detect features in the environment. The method also involves establishing a correlation between features detected in different images, and using location information from the navigation system to localize a feature detected in different images. Further, the method involves generating a flight log that includes the localized feature. Also, the method involves detecting a failure involving the navigation system, and responsively operating the camera to capture a post-failure image. The method also involves identifying one or more features in the post-failure image, and determining a location of the UAV based on a relationship between an identified feature and a localized feature.

Abstract: Systems and methods for image based localization for unmanned aerial vehicles (UAVs) are disclosed. In one embodiment, a method for navigating a UAV includes: flying a UAV along a flight path; acquiring an image of a ground area along the flight path with a camera carried by the UAV; and sending the image to a base station. The method further includes receiving navigation data from the base station, based upon a comparison of the image of the ground area to at least one terrestrial map of the flight path.
