Abstract: Disclosed are a tracking and identification method and system and an aircraft. The method includes: obtaining, by a first aircraft, a first feature parameter of a target object; if image data captured by the first aircraft does not match the first feature parameter, adjusting the first aircraft to a predetermined high-altitude area relative to the target object according to location information of a second aircraft that is sent by the second aircraft or location information of the target object, where the second aircraft is in a predetermined low-altitude area relative to the target object, and image data captured by the second aircraft matches a second feature parameter of the target object.

Abstract: The present invention relates to the field of electronic photographing technologies, and provides a method, a control apparatus and a system for tracking and shooting a target. The method includes: in a tracking and shooting process, controlling, by a control apparatus, a photographing apparatus on an unmanned aerial vehicle to collect an image, and obtaining the collected image; selecting a tracked target in the image; calculating a movement speed, a movement direction and a location on the current image that are of the tracked target according to comparison between consecutive neighboring frame images; and controlling, according to the calculated movement speed, movement direction and location on the current image, the unmanned aerial vehicle to track the tracked target, so that the tracked target is always located on the image collected by the photographing apparatus.

Abstract: A flight device and a flight control method are disclosed. The method includes: acquiring an image and a height of the flight device; determining a scene in which the flight device is currently located; calculating an image X-offset and an image Y-offset of a second image frame of two adjacent image frames relative to a first image frame of the two adjacent image frames; compensating for the image X-offset and the image Y-offset according to the acceleration and the angular velocity of the flight device to obtain image correction offsets comprising a corrected image X-offset and a corrected image Y-offset; calculating an X-offset and a Y-offset in world coordinates corresponding to the image correction offsets; and deriving a velocity of the flight device.

Abstract: This disclosure discloses a target tracking method and an aircraft. The method includes: obtaining an image captured by each of at least two cameras at a same time point, where photography directions of the at least two cameras are different; stitching the images to obtain a panoramic image; and if a target object is identified in the panoramic image, tracking the target object. Efficiency of identifying the target object may be improved by using the panoramic image, and effective tracking may be performed on the identified target object.
