Problems solved by technology

According to the search results, the current near-infrared spectroscopy and computer vision technologies are mainly used for the classification, grading and internal active ingredient detection of tea products. There are no relevant patents at home and abroad on the use of these technologies to identify the authenticity of famous teas
In addition, from the perspective of the technical means used, most of them only use a single detection technology, which has certain limitations

Embodiment Construction

[0022] The present invention has universality for fast and non-destructive identification of the authenticity of famous and high-quality teas, but because there are many kinds of famous and high-quality teas, the present invention only gives an implementation example for the authenticity identification of the famous and excellent tea Biluochun, a special product in Jiangsu, and the authenticity of other famous and high-quality teas can be referred to According to the method of the implementation example, a new authenticity identification model is established specifically for the tea sample to be tested, so that the authenticity of the famous tea sample can be tested.

[0023] Example implementation steps refer to figure 1 , for an example implementation see figure 2 . First select a batch of authentic and counterfeit Biluochun samples (generally more than 100 samples) for model calibration. The authenticity of the Biluochun samples is identified through sensory evaluation by...

Abstract

The invention discloses a hyperspectrum image technique-based method and a hyperspectrum image technique-based device for identifying true and false famous tea, which relate to a method and a device for identifying true and false famous tea. The device consists of the following parts: a camera (1), an imaging spectrometer (2), a light source (3), a Y-type optical fiber (4), a sample cell (5), a mobile platform (6), a closed light both (7) and a computer (8), wherein the camera (1) and the imaging spectrometer (2) are closely connected and vertically arranged above a conveying device on the mobile platform (6); the sample cell (5) is arranged on the mobile platform (6); the light source (3) is connected with the Y-type optical fiber (4); and emitted light enters the closed light both (7) through the Y-type optical fiber (4) and uniformly projected onto the sample cell (5). The hyperspectrum image technique-based method comprises the following steps: (1) building a knowledge base first;(2) acquiring hyperspectrum image data; (3) preprocessing data and extracting characteristic information; and (4) building a model and identifying an unknown sample. The device and the method have the advantages of quick detection speed and simple and convenient operation.

Description

Technical field [0001] The invention relates to a method and device for identifying the authenticity of famous tea, in particular to a method and device for authenticating famous tea based on hyperspectral image technology. Background technique [0002] At present, China's tea market is relatively chaotic, especially in the famous tea market. Due to the high price of famous tea and the large profit margin of products, this has led to the phenomenon of shoddy and fake ones in my country's famous tea market to a certain extent. In pursuit of higher profits, some unscrupulous tea processing enterprises buy fresh leaves from other places, use the same processing method as the famous tea to obtain counterfeit products with very similar external shape and characteristics, and then brand them as famous tea trademarks in the market. , This not only damages the interests of consumers, but also is not conducive to the brand protection of my country's famous tea. For a long time, the i...
