Abstract: A method of controlling flight of an unmanned aerial vehicle (UAV) includes collecting, while the UAV traverses a flight path, a set of images corresponding to different fields of view of an environment around the UAV using multiple image capture devices, extracting one or more image features from the set of images, constructing a map of the environment using one or more selected image features from the one or more image features, and generating a return path for the UAV using the map of the environment. Each of the multiple image capture devices includes one of the different fields of view.

Abstract: Automatic terrain evaluation of landing surfaces, and associated systems and methods are disclosed herein. A representative method includes receiving a request to land a movable object and, in response to the request, identifying a target landing area on a landing surface based on at least one image of the landing surface obtained by the movable object. The method can further include directing the movable object to land at the target landing area.

Abstract: A method of controlling flight of an unmanned aerial vehicle (UAV) includes collecting, while the UAV traverses a flight path, a 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 includes one of the different fields of view. The method further includes extracting a set of feature points from the set of images and selecting a subset of feature points from the set of feature points to be stored based on a number of image capture devices that collect images including the subset of feature points to aid navigation of the UAV.

Abstract: A method for acquiring an obstacle distance including determining a detection mode for detecting an obstacle distance of an obstacle; detecting the obstacle distance using the detection mode. Detecting the obstacle distance includes in response to determining a monocular mode as the detection mode: capturing a first image and a second image using a lens of an imaging device at two different times with a predetermined monocular imaging interval at two different locations; and calculating the obstacle distance via a monocular triangulation based on the first image, the second image, and a displacement of the imaging device between the two different times. Both the first image and the second image contain the obstacle. The predetermined monocular imaging interval varies based upon an altitude of the imaging device changes.

Abstract: A method of distance measuring includes obtaining a depth map and a stereo pair of images of a scene of interest, and enhancing a precision of the depth map based on disparity values of corresponding points between the images. The images have a higher resolution than the depth map. Enhancing the precision of the depth map includes optimizing an energy function of the images over a predetermined range of disparity values to obtain an optimized energy function; determining the disparity values based on the optimized energy function; and replacing low precision values of the depth map with corresponding high precision values based on the disparity values.
