Illumination control method and system based on relative positions of indoor personnel and lamp

The invention provides an illumination control method and system based on relative positions of indoor personnel and lamps. The method comprises the following steps: acquiring a video image including the personnel and the lamps; processing the acquired video images through a multi-target detection algorithm to obtain image coordinates of the personnel and the lamps; processing the obtained video image through a monocular depth estimation algorithm to obtain a depth value of each pixel in the video image; according to the depth value of each pixel in the video image and the image coordinates of the personnel and the lamps, the relative positions of the personnel and the lamps are calculated; and according to the relative positions of the personnel and the lamps, clustering analysis is carried out by adopting a K-Median clustering algorithm, and the lamps are controlled to be turned on according to a clustering analysis result. The position is subjected to clustering analysis by adopting a K-Median clustering a
