Abstract
The invention discloses a lamp control system based on a mode of starting light regionally. The system comprises a camera, an image analysis module, a processor, a controller, and a plurality of brightness sensors and a plurality of LED laps mounted in different regions. The camera is used for photographing a dynamic image of a user. The image analysis module is used for analyzing the region in which the user is located according to the dynamic image of the user. The processor generates a data collection instruction to the brightness sensor corresponding to the region in which the user is located. The brightness sensor collects a brightness value of the region in which the user is located, and feeds back the brightness value to the processor. The processor judges whether the brightness value is smaller than a preset brightness threshold value corresponding to the region in which the user is located or not. The processor generates a control instruction to the controller if the brightness value is smaller than the preset brightness threshold value. The controller controls the LED lamp corresponding to the region in which the user is located to be started according to the control instruction.
