Embodiment Construction

[0053] The invention is a traditional painting pigment identification system and identification method based on multi-spectral imaging technology. The system specifically includes an image acquisition and processing system based on a camera and an image processing unit, and a spectroscopic system composed of a band-pass filter set. The unit is equipped with a pigment spectral reflectance reconstruction algorithm, a painting pigment sample database and its spectral reflectance characteristic database.

[0054] see figure 1 , the components of the preferred embodiment of the paint identification system of the present invention include an illumination light source 1, a band-pass filter set 3 and a camera 5, and the band-pass filter set 3 consists of a plurality of optical filters 4 corresponding to different spectral bands Composition, the camera 5 is connected to the image processing unit 6 . The painting to be tested 2 is placed flat on the manuscript table, and the camera 5 is ...

Abstract

The invention relates to a painting pigment identification system based on multispectral imaging and a method thereof. The system comprises an illumination light source, a band-pass filter group and acamera, the band-pass filter group is composed of several optical filters corresponding to different spectrum segments, the camera is connected with an image processing unit, the illumination light source is used for emitting the illumination light to a to-be-measured paint, and the light reflected by the to-be-measured paint passes through the optical filters and then penetrates into the camera.The technical problems of intervention type, damage, and low efficiency existed in the current painting pigment identification methods based on chemical analysis or based on substance interaction effect can be solved. The identification system and the method have the advantages of high spatial resolution, high precision, non contacting, and no damage.

Description

technical field [0001] The invention relates to a system and method for identifying paint pigments based on multispectral imaging. Background technique [0002] At present, the identification methods of traditional painting pigments are mainly divided into three categories: the first category is the method of chemical analysis. This method has high analysis accuracy, but it needs to sample from the painting itself, and the analysis results are only valid for the samples and cannot be inferred. and the area outside the sampling location; the second type includes X-ray diffraction, laser Raman spectroscopy analysis methods based on the interaction of light or rays and matter, such methods have better analysis results, but because the analysis process often involves in molecular The excitation of pigments at the atomic level will lead to changes in the molecular structure of pigments, thus becoming a destructive analysis method. Due to the particularity of painting cultural rel...
