Abstract

Some ancient murals were found to be repainted on the surface of the original murals to form multi-layer murals. The patterns on the original layer are of great significance for studying the social and cultural behavior in that time. The hyperspectral imaging covers the visible and near-infrared bands, which has advantages for the information extraction of multi-layer murals. Therefore, a method to study the transmission performance of hyperspectral imaging on multi-layer simulated mural samples is proposed. By making mural samples, the mineral pigment painted on the surface is covered with 0-11 different layers of lime water. Then the samples were collected with hyperspectral images, and the method of principal component analysis and band calculation were used to analyze the enhancement effect of the mural patterns covered by different layers of lime water. The results show that hyperspectral imaging has certain transmittance to the interior of the mural and can enhance internal pigment information. The research results can support the information extraction of multi-layer murals to some extent.
