Abstract
A target tracking method for an air vehicle includes steps of: during a flight of an air vehicle main body to a position corresponding to a global positioning system (GPS) positioning signal, taking pictures of an area where a reference target is located by a camera, and obtaining a reference image; extracting reference image characteristics of the reference target and initial position information of the reference target in the reference image from the reference image; when the camera obtains a temporary image showing a temporary target, extracting temporary image characteristics of the temporary target and temporary position information of the temporary target in the temporary image from the temporary image; if the reference image characteristics are consistent with the temporary image characteristics, calculating a deviation direction according to a difference between the initial position information and the temporary position information; and tracking the temporary target in the deviation direction.
