Abstract: A method for supporting aerial operation over a surface includes obtaining a representation of the surface that comprises a plurality of flight sections, and identifying a flight path based on the representation of the surface. The flight path allows an aircraft, when following the flight path, to conduct an operation over the flight sections.

Abstract: A method for identifying a photovoltaic panel includes: acquiring a grayscale image of an infrared image captured by a camera mounted on a UAV, the grayscale image including an image of a photovoltaic panel; performing edge extraction processing on an image in the grayscale image to obtain a monochrome image including a plurality of horizontal lines and a plurality of vertical lines, the horizontal lines being lines in a first direction, an average length of the lines in the first direction being greater than a preset length, the vertical lines being lines in a second direction, and an average length of the lines in the second direction being less than the preset length; and identifying the photovoltaic panel in the monochrome image based on a relative positional relationship between the horizontal lines and the vertical lines in the monochrome image.

Abstract: An image processing method includes obtaining an acquired image captured by an image acquisition device and obtaining vibration information associated with the acquired image and generated while the image acquisition device capturing the acquired image. The vibration information includes an angle of vibration. The method further includes performing a distortion correction to the acquired image to obtain a distortion-corrected image based upon the vibration information and a preset distortion correction parameter, and determining a target image from the distortion-corrected image based upon the vibration information.

Abstract: A method for supporting aerial operation includes obtaining a real-time location of an aircraft, obtaining a location of a supply station, obtaining a location of a next waypoint, and controlling the aircraft based on a status parameter related to a flight status of the aircraft associated with the real-time location of the aircraft. Controlling the aircraft includes controlling, in response to the status parameter satisfying a first preset condition, the aircraft to fly to the next waypoint; and controlling, in response to the status parameter satisfying a second preset condition, the aircraft to fly to the supply station.
