An unmanned aerial vehicle, comprising:

• a body;
• arms, connected to the body;
• a power apparatus, disposed on the arm and configured to provide power for the unmanned aerial vehicle to fly;
• a photographing device, disposed on the body, wherein the photographing device comprises a gimbal and a camera mounted on the gimbal;
• a vision chip, wherein the vision chip is disposed in the body and is configured to identify and lock a moving target;
• and
• a flight controller, wherein the flight controller is disposed on the body and is communicably connected to the vision chip and the flight controller is configured to:
• adjust a moving state of the unmanned aerial vehicle and/or parameters of the photographing device according to a moving state of the moving target, so that the moving target is always located on a display screen of a control terminal with a preset size, wherein the control terminal is communicably connected to the unmanned aerial vehicle;
• adjust a speed of the unmanned aerial vehicle according to a speed change rate of the moving target in a moving direction of the unmanned aerial vehicle, so that the moving target in the preset size is always located at a preset position on the display screen, wherein the vision chip is further configured to:
• acquire a plurality of images of the moving target through the photographing device;
• extract features of the moving target based on the plurality of images of the moving target, wherein the features of the moving target comprise at least one of a texture feature, a shape feature, or a spatial feature.
