Problems solved by technology

However, its invention is for quantitative analysis of seeds, and cannot be used for qualitative analysis of seeds to identify the authenticity of seeds.
[0005] Another example is W.Kong et al. (2013) used near-infrared hyperspectral imaging technology combined with multivariate data analysis methods to identify four rice varieties, and compared the identification results of the optimal spectral section and the full-band s

Abstract

The invention relates to rice seed identification and particularly discloses a construction method of a rice seed variety authentication identifying model and application thereof. Specifically, the construction method comprises the steps of collecting diffuse reflection and diffuse transmission spectra of samples, selecting effective wavelength to sequentially average and standardize moving windows, utilizing PCA + LDA to perform dimensionality reduction, utilizing BPR to perform modeling, conducting the same processing on the samples to be detected, then performing comparison and judging variety authentication. The optimal dimensionality reduction method is adopted to perform dimensionality reduction processing and improve the correct identification rate for different varieties of samples.

Description

technical field [0001] The invention relates to rice seed identification, in particular to a construction method and application of a rice seed variety authenticity identification model. Background technique [0002] Agriculture is the foundation of the country. Seeds are extremely important means of production in the process of agricultural production. The quality of seeds will directly affect the yield, quality and benefits of food. In my country, a country with a rapidly developing market economy, a vast territory and a large population, the supervision of the seed market is not enough, and the relevant laws and regulations and the supervision mechanism are not perfect, which gives some criminals an opportunity to take advantage of the counterfeit and shoddy products in the market. Illegal phenomena such as illegal phenomena occur frequently, criminals use non-brand seeds to fake real ones, pretend to be other well-known varieties, or replace seeds of this brand with half-...
