1. An aircraft, comprising:a camera;
a sensor configured to detect a flight height of the aircraft;
a light emitting apparatus; and
a processor configured to:
obtain ambient luminance data by using the camera, wherein the ambient luminance data indicates ambient luminance of an environment;
determine whether the flight height is less than a preset low-altitude height threshold;
determine whether the aircraft is in a low-light environment based on the ambient luminance data; and
adjust a working status of the light emitting apparatus based on a determination that the flight height is less than the preset low-altitude height threshold and that the aircraft is in the low-light environment.
