An image processing method for a unmanned aerial vehicle includes: aligning a subject matter by a camera of the unmanned aerial vehicle focusing on the subject matter at A first time, and recording images information in a focus flame as first reference pattern, presetting a separation distance of automatic movement of the unmanned aerial Vehicle, focusing on the subject matter at a second time, and recording image information in the focus frame as a second reference pattern, synthesizing a three-dimensional reference pattern of the subject matter according to the first reference pattern and the second reference pattern, automatically traversing images in whole camera aperture by the focus frame when the unmanned aerial vehicle detects interrupt of controlling signal, and comparing with the three-dimensional reference pattern. If the subject matter cannot be found, location of the unmanned aerial vehicle is automatically adjusted until the subject matter reappears on the camera aperture: presetting a reference straight line between the camera and the subject matter, controlling movement of the unmanned aerial vehicle along the reference straight line, and monitoring moving state of the unmanned aerial vehicle via a three-axis gyroscope. If the unmanned aerial vehicle deviates from the reference straight line in flight, a new reference straight line is reset and the movement of the unmanned aerial vehicle along the new reference straight line is controlled, obtaining distance of movement of the unmanned aerial vehicle along the reference straight line via the three-axis gyroscope, and recording a ratio of display widths of the subject matter before the camera is moving and after the camera is moving, and calculating measuring distance between the camera and the subject matter. If the measuring distance is more than a presetting reference distance, the unmanned aerial vehicle is controlled to move to subject matter until the measuring distance is less than or equal with the presetting reference distance.
