3D concrete printing surface smoothness evaluation method

The invention relates to the technical field of smoothness evaluation, in particular to a 3D concrete printing surface smoothness evaluation method which comprises the following steps: preparing a printing sample, selecting a standard 3D printing concrete material, and preparing the printing sample by utilizing 3D printing equipment according to preset printing parameters; performing preliminary surface detection, performing real-time monitoring by using a high-resolution camera, and performing preliminary evaluation on the surface of the printing sample in the printing process; adjusting parameters in real time; fine measurement is carried out, and after printing is completed, a surface roughness meter is used for carrying out fine surface smoothness measurement on the sample; scanning a three-dimensional surface; performing comprehensive processing on the data obtained in the step S1 to the step S5, and applying an image processing and data analysis technology to obtain a comprehensive evaluation index valu
