[0034] Specific implementation mode 1. Combination figure 1 As shown, the present invention provides a kind of method for distinguishing alcoholic goods from the outside of the light-transmitting packaging bottle, including the identification of authenticity:

[0035] Model training: Obtain conventional Raman spectra of different brands of wine products with light-transmitting packaging bottles, use principal component analysis to reduce the dimensionality of conventional Raman spectra to obtain spectral data after dimensionality reduction, and use spectral data after dimensionality reduction to analyze SVM The classification model is trained so that the spectral data after dimension reduction obtains the classification area represented by the classification label, thereby determining the SVM classification detection model;

[0036] Commodity identification: use a Raman spectrum detector to collect the Raman scattering spectrum of alcoholic products from the outside of the tra...

Abstract

The invention discloses a method for identifying wine commodities from the outside of a light-transmitting packaging bottle, and belongs to the technical field of wine commodity identification. The invention aims to solve the problem that the difference of Raman spectrums of different wine commodities is fine, so that wine identification is difficult to carry out by a method for identifying the difference between the spectrums. The method comprises the following steps: determining an SVM classification detection model by adopting dimension-reduced spectral data; collecting the Raman scattering spectrum of the wine commodity from the outside of the light-transmitting packaging bottle by adopting a Raman spectrum detector; carrying out dimension reduction processing on the Raman scattering spectrum by using a principal component analysis method to obtain a dimension-reduced spectrum to be identified; inputting the to-be-identified spectrum after dimension reduction into an SVM classification detection model to obtain a classification region represented by a classification label; comparing the classification areas with known classification areas of the to-be-identified wine commodity, and if the classification areas are the same, determining that the identification result is true wine, otherwise, determining that the wine is adulterated wine. The method is used for lossless identification of wine commodities.

Description

technical field [0001] The invention relates to a method for identifying wine products from the outside of a transparent packaging bottle, and belongs to the technical field of wine product identification. Background technique [0002] Liquor products include various types of liquor, wine, beer, rice wine and foreign wine. As a commodity, wine has a large price range according to its brand and year: the price of a bottle of wine ranges from tens of yuan to thousands of yuan; therefore, some criminals use ordinary wine with the same packaging to pretend to be high-end Wine sales, and then seek high profits. Because the appearance and packaging of fake wine are exactly the same as genuine wine, it is difficult for dealers or consumers to identify the authenticity, which will incur economic losses. [0003] At present, there are two main methods to identify the authenticity and age of wine products: one is to invite wine tasting experts to conduct manual identification by tas...
