Abstract
The present disclosure relates to a method for identifying a visitor. The method for identifying a visitor is applied in an access control system. The access control system includes a control terminal, a door device and an illumination lamp. The illumination lamp provides lighting for a visitor. The method for identifying a visitor includes: receiving a real-time image of a current visitor outside a door from a door device; obtaining first encoded information extracted from a first optical signal corresponding to environmental light of the visitor's current environment; and identifying the visitor as an authorized visitor when the image matches with a preset image and the first encoded information contains preset encoded information. The preset image is pre-stored image information of the authorized visitor. The preset encoded information is consistent with encoded information embedded in an optical signal of an illumination lamp for illuminating the environment.
