Leather product material identification method based on hyperspectral imaging technology

Abstract

The invention discloses a leather product material identification method based on hyperspectral imaging technology. The method specifically comprises the following steps: step 1, collecting a leather product sample; step 2, identifying the leather product sample by using a hyperspectral imaging device: scanning the collected leather product sample by using the hyperspectral imaging device, collecting a hyperspectral image, extracting a characteristic wavelength of a spectral curve of each pixel of the hyperspectral image, establishing a standard characteristic library based on the characteristic wavelengths of the collected leather product sample, establishing a verification set based on the characteristic wavelength of the leather product to be detected; step 3, establishing a set of classifiers based on multiple groups of characteristic wavelengths of different leather products in the standard characteristic library; and step 4, obtaining the material components of the leather product to be detected. The invention relates to the field of leather product identification, and particularly provides a method for identifying a leather product material based on a hyperspectral imaging technology, which can quickly, conveniently, accurately and losslessly obtain material attributes of textiles.

Description

technical field [0001] The invention relates to the field of leather product identification, in particular to a method for material identification of leather products based on hyperspectral imaging technology. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning; leather is composed of natural protein fibers tightly woven in three-dimensional space, and its surface has a special grain layer with natural grain.
