| 摘 要： | In order to effectively remove the surface paint of the cultural relic of white marble, the area extrapolation method and laser-induced plasma spectroscopy (LIPS) method were used to obtain the ablation threshold power of the gold, silver paint layer and white marble surface. On the basis of this, the optimal laser power for removing paint without damaging the white marble substrate was determined. The image processing method was used to study the cleaning degree and variation trend of cleaning rate of the gold and silver paint on the surface of 10 mm×10 mm white marble by laser cleaning, and the optimal laser spot overlap rate and the optimal cleaning times were obtained. Finally, the image processing method was used to evaluate the cleaning effect of laser cleaning of paint layer on the white marble surface. More than 93% of the cleaning degree shows that the synergistic use of the area extrapolation method, LIPS method and image processing method can effectively improve the laser cleaning efficiency of the paint layer on white marble surface.
