The invention discloses a method and a system for realizing uniform dimming of illumination in a high-power LED (light-emitting diode) area, and relates to the technical field of data processing. The method comprises the following steps: acquiring people flow distribution data of a target area and illumination data of a plurality of segmented illumination areas in the target area; based on the people flow distribution data, determining a distribution position and a coverage range of dense people flows in the target area; calculating a distance value between each segmented illumination area and the distribution position of the dense people stream, and determining an illumination demand level corresponding to each distance value; the illumination compensation value of each segmented illumination area is determined by combining the illumination demand level and the illumination data of each segmented illumination area, and the light emitting angle of each segmented illumination area is determined by combining the distribution position and the coverage range of the dense people stream; and adjusting the LED lamp group of each segmented illumination area according to the illumination compensation value and the light emitting angle of each segmented illumination area so as to illuminate the target area. By implementing the technical scheme provided by the invention, the effect of improving the efficiency of uniform dimming of area illumination is achieved.
