Embodiment 1

[0044] A kind of non-destructive detection method for leather based on spectral analysis provided by the present invention, the specific steps are as follows, as figure 1 Shown:

[0045] S101. Establish a spectral database:

[0046] The manufacturer or developer of the leather detection system is responsible for using known types of leather samples, pre-collecting leather sample spectral data, and setting attribute label information (leather sample type) for each set of sample spectral data, and converting all The sample spectral data and the corresponding attribute label information are stored in the spectral database;

[0047] S102, spectral data acquisition and preprocessing:

[0048] Classify the sample spectral data of the spectral database according to the attribute label information, and obtain a leather spectral model, and store it in a leather spectral model library;

[0049] S103. Real-time detection of leather spectrum:

[0050] In the shopping mall, consumers use...

Embodiment 2

[0062] Another aspect of the present invention, such as figure 2 As shown, in order to realize the above-mentioned leather non-destructive testing method based on spectral analysis, the present invention also provides a leather non-destructive testing system based on spectral analysis, including a spectral detection terminal and a server end, the spectral detection terminal is used for pre-collecting The sample spectral data of leather, and set attribute tag information for each group of described sample spectral data; And collect the leather spectral data that needs to detect; Described server end comprises spectral database, comparison processing module and leather spectral model storehouse; All The spectral database is used to store the sample spectral data and the corresponding attribute label information, and the comparison processing module is used to classify the sample spectral data through a machine learning algorithm to obtain a leather spectral model, which is store...

Abstract

The invention discloses a leather nondestructive testing method and a leather nondestructive testing system based on spectral analysis and aims at solving the problem that an existing leather detecting method cannot quickly and accurately carry out nondestructive testing on leather. The method comprises the following steps: establishing a spectral database; acquiring sample spectra data of the leather in advance, setting attribute tag information for each group of sample spectra data, and storing the sample spectra data and the corresponding attribute tag information in the spectral database; preprocessing the spectral data; classifying the sample spectra data of the spectral database according to the attribute tag information, obtaining a leather spectral model, and storing the leather spectral model into a leather spectral model base; detecting a leather spectrum in real time; and acquiring the leather spectra data needing to be tested, comparing the acquired leather spectra data with the leather spectral model, and outputting a leather testing result needing to be tested.

Description

technical field [0001] The invention relates to the technical field of leather identification, in particular to a nondestructive detection method and system for leather based on spectral analysis. 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. There is a special grain layer on the surface, which has natural grain and luster, and feels comfortable. Leather products are common daily necessities in life, such as boxes, bags, gloves, ticket holders, belts, etc., are indispensable daily necessities in people's lives, and the demand for leather in shoes, clothing, bags, furniture, auto parts, decoration, etc. is also Every day. Generally speaking, the fabrics of medium and high-end bags and bags are mainly natural leather materials. At present, there are many kinds of leather o...
