Shop signboard health performance evaluation method and device

The invention discloses a shop signboard health performance assessment method and device, and belongs to the technical field of shop signboard health performance assessment, and the method comprises the steps: selecting a plurality of points on different light-emitting surfaces of a to-be-assessed shop signboard, measuring the brightness and spectrum corresponding to each point, and calculating the color coordinate of each measured point according to the spectrum; based on the chromaticity coordinates and the brightness value, calculating to obtain red, green and blue three-channel radiation brightness and nine-channel radiation brightness of the measured light source, and correspondingly generating a three-channel light-emitting material and a nine-channel light-emitting material; measuring and establishing a three-dimensional model of the signboard, and calculating the area of the luminous material; based on the three-channel light-emitting material and the three-dimensional model, simulating to obtain the
