AI Technical Summary

Technical Problem

Traditional porcelain identification methods rely on empirical visual evaluation, which is highly subjective, destructive, and has limited data dimensions. It is difficult to accurately identify the microscopic features of the glaze and the differences in material composition of modern imitations. Existing optical image analysis and spectral detection methods cannot effectively distinguish between natural crazing and artificial imitation patterns, and lack sensitivity to slight differences in chemical composition.

Method used

A multimodal data fusion method is used to obtain the grayscale information, bubble distribution status, spectral reflectivity and mineral element characteristics of the glaze image, and a multidimensional dynamic identification model is constructed. The authenticity of porcelain is identified by combining the microtexture, bubble group distribution, multispectral reflectivity and mineral element fingerprint characteristics.

Benefits of technology

It realizes non-destructive, high-precision authentication of porcelain authenticity, can effectively distinguish between natural and imitation patterns, improves the ability to identify highly simulated counterfeits, reduces the interference of artificial imitation patterns, and enhances the anti-interference ability and traceability of authentication.

Abstract

The invention relates to the technical field of image processing, in particular to a porcelain fingerprint verification method and device and a storage medium, and the method comprises the steps: collecting a glaze image and mineral element data; determining a texture coefficient of the glaze image; acquiring the diameter of each bubble in the grayscale image, partitioning the grayscale image, acquiring the bubble number of each partition, and judging the bubble distribution state of the glaze layer based on the bubble diameter and the bubble number of each partition; determining porcelain spectral characteristics; determining the authenticity of the porcelain based on the texture coefficient of the glaze image, the distribution state of bubbles in the glaze layer and the spectral characteristics of the porcelain; and determining an adjustment factor based on the porcelain glaze fluorescence decay time, determining porcelain mineral element fingerprints based on the collected mineral element data, and updating the porcelain authenticity determination process based on the element mineral fingerprints and the adjustment factor. According to the invention, the accuracy of porcelain fingerprint verification is effectively improved.
