    Abstract: A computer-implemented method for controlling a UAV includes identifying a set of target markers based on a plurality of images captured by an imaging device carried by the UAV, and controlling the UAV to fly based on the set of target markers. The set of target markers include at least two or more types of target markers and are in close proximity to be detected within a same field of view of the imaging device. Controlling the UAV to fly includes controlling the UAV to approach the set of target markers based at least in part on a spatial relationship between the UAV and a first type of target marker; and determining whether to control the UAV to land at or near the set of target markers based on information conveyed by a second type of target marker.

    Abstract: A method for recognizing a posture includes acquiring a depth image of a scene, and obtaining point clouds of an operator based on the depth image of the scene. The method also includes separating point clouds of an arm from the point clouds of the operator and obtaining a characteristic point from the point clouds of the arm. The method further includes determining a location relationship between the characteristic point and the operator and determining a posture of the operator based on the location relationship.

    Abstract: A method includes obtaining a spatial configuration of a plurality of imaging devices relative to one another and to a movable object. The imaging devices are coupled to the movable object and comprise a first imaging device configured to operate in a multi-ocular mode and a second imaging device configured to operate in a monocular mode. The method further includes determining at least one of a distance of the movable object to an object or surface lying within a field-of-view of at least one of the imaging devices, a disparity between matched points in stereoscopic images acquired by the first imaging device, or an environment in which the plurality of imaging devices are operated. The distance is determined based in part on the spatial configuration. The method also includes selecting either the first imaging device or the second imaging device to acquire image data based on the determination.

    Abstract: The present disclosure relates to systems, methods, and computer-readable storage devices for the coordination of actions between movable objects. For example, a method may coordinate actions between at least a first and a second movable object. The method may detect, by the first movable object, the position of a target. The method may control the position of a first movable object based on the position of the target. A command may be received for the first movable object to perform an action in coordination with the second movable object. In some embodiments, the command may be to take images of the target to create a bullet time effect.
