Abstract: The present disclosure provides a data processing method for a direct memory access (DMA) controller. The method includes acquiring feature information of two or more original output feature maps, and generating DMA read configuration information and DMA write configuration information of the original output feature maps based on the feature information of each original output feature map; and reading input data from the original output feature map based on the DMA read configuration information of the original output feature map, and storing the read input data to a target output feature map based on the DMA write configuration information of the original output feature map for each original output feature map.

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: A method is provided for controlling flight of an aircraft carrying an imaging device. The imaging device is mounted at a gimbal. The method includes in response to receiving a triggering operation that triggers the aircraft to operate in an image control mode, obtaining an environment image captured by the imaging device, recognizing a gesture of a target user in the environment image, and in response to recognizing that the gesture of the target user is a start-flight gesture, generating a takeoff control command to control the aircraft to take off. Obtaining the environment image includes after obtaining the triggering operation, controlling the gimbal to rotate to control the imaging device to scan and photograph in a predetermined photographing range, and obtaining the environment image including a characteristic part of the target user that is captured by the imaging device through scanning and photographing in the predetermined photographing range.
