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 controlling a movable object includes receiving, at one or more processors, a plurality of images from a plurality of imaging devices carried by the movable object; determining, with aid of the one or more processors, an environment type of an environment surrounding the movable object; identifying a target based on the plurality of images and the environment type; determining information of the target based on the plurality of images; and controlling the movable object to avoid the target based on the information of the target. The plurality of imaging devices includes a first imaging device arranged at an upper surface of a body of the movable object and a second imaging device arranged at a lower surface of the body. Each of the first imaging device and the second imaging device has a field of view greater than 150 degrees.

Abstract: An imagery method includes obtaining a plurality of images of an object and selecting one or more images related to a moment from the plurality of images based on a selection rule. The plurality of images are captured by one or more imaging devices within a period of time while the object is being tracked. A plurality of triggers each are configured to trigger at least one of a starting time or a stopping time of the period of time for capturing the plurality of images. The plurality of triggers include a detection based on motion/state estimation of the object.

Abstract: The present disclosure provides a focusing method for an electronic device having a camera. The focusing method includes while capturing a target scene, determining a change in a relative position between the electronic device and the target scene. The relative position includes a distance between the electronic device and the target scene and/or an orientation of the target scene with respect to the electronic device. The focusing method further includes determining a focusing scheme according to the change in the relative position between the electronic device and the target scene; and focusing on an object to be tracked and photographed according to the determined focusing scheme. The object to be tracked and photographed is a part of the target scene.

Abstract: A method for controlling a movable object includes obtaining current location information of an obstacle while the movable object tracks a target, and determining whether a location of the obstacle corresponds to a reactive region relative to the movable object based on the current location information of the obstacle. In response to determining that the location of the obstacle corresponds to the reactive region, one or more movement characteristics of the movable object is adjusted in a reactive manner to prevent the movable object from colliding with the obstacle. In response to determining that the location of the obstacle does not correspond to the reactive region, the one or more movement characteristics of the movable object is adjusted in a proactive manner to maintain a distance between the movable object and the obstacle to be larger than a predefined distance.

Abstract: An obstacle detection method includes obtaining a base image captured by a camera of a moveable object while the moveable object is at a first position and extracting an original patch from the base image. The original patch corresponds to a portion of the base image that includes a feature point. The method further includes obtaining a current image captured by the camera while the moveable object is at a second position, determining a scale factor between the original patch and an updated patch in the current image that corresponds to a portion of the current image that includes the feature point with an updated location, and obtaining an estimate of a corresponding object depth for the feature point in the current image based on the scale factor and a distance between the first position and the second position.
