Intelligent regulation and control method and system for light of terminal public area

The invention discloses an intelligent regulation and control method and system for terminal public area lamplight, and belongs to the technical field of lamplight regulation and control. The intelligent regulation and control method comprises the steps that an overall channel of a terminal is divided into at least two fixed areas, and the divided fixed areas are numbered; and on the basis of the field video stream of the target area, analyzing the field people stream condition of the target area, and adjusting the field illumination intensity of the target area and/or the adjacent area according to the field people stream condition of the target area. The intelligent regulation and control system comprises a region division module, a people flow analysis module and a light intensity adjustment module. The system can accurately monitor real-time pictures and light illumination conditions on site, check people flow identities through face comparison, combine flight information and people flow directions, perfo
