Near infrared spectrum gentian identification method and system

Abstract

The invention relates to a near-infrared spectrum gentian identification method and system. According to the near-infrared spectrum gentian identification method provided by the invention, the spectral data of the to-be-detected gentian is obtained, and the to-be-detected gentian can be rapidly, losslessly, efficiently and accurately detected by utilizing the constructed partial least square method identification model, so that the specific type of the to-be-detected gentian can be identified. Therefore, the near-infrared spectrum gentian identification method and system provided by the invention have the characteristics of low cost, simplicity in operation, high detection speed, few required samples, no pollution, high detection precision, strong reliability and the like.

Description

technical field [0001] The invention relates to the field of spectrum detection, in particular to a near-infrared spectrum gentian identification method and system. Background technique [0002] Plants of the genus Gentiana mostly grow in high mountains or plateaus, where the climate conditions are extreme and changeable. Due to the difference in the growth environment and the growth period of Yunnan gentian, there are obvious differences between domestic species and wild species in some aspects. In appearance, the domestic species is fat and loose, while the wild species is thin and firm. In addition, the wild ones generally have a longer growth period, more balanced and rich ingredients, and better curative effect. There are problems such as irregular planting techniques and hormone abuse in domestically grown medicinal materials. Therefore, it is particularly important to identify wild Chinese herbal gentian. [0003] In terms of traditional technical means, the quality ...

Problems solved by technology

Moreover, the wild ones generally have a longer growth period, more balanced and rich ingredients, and better curative effect. There are problems such as irregular planting techniques and hormone abuse in domestically grown medicinal materials.

[0003] In terms of traditional technical means, the quality of gentian is mainly determined by chemically measuring the composition ratio and content value of various nutrients in gentian. This method has the advantages of good repeatability and high accuracy, but it has the disadvantages of high labor cost and high operating cost. Complicated and other shortcomings, and it takes a long time from sampling to result output, which cannot meet the needs of real-time and rapid detection in the market
