Single hybrid rice seed variety identification method based on hyperspectrum

Abstract

The invention discloses a single hybrid rice seed variety identification method based on hyperspectrum, and relates to the technical field of key grain crop variety authenticity detection, in particular to a single hybrid rice seed variety identification method based on hyperspectrum. Comprising the following steps: S110, acquiring hyperspectral images of various different varieties of hybrid rice seed samples based on the wavelength of a halogen lamp light source; according to the method, the single-grain images of the rice seeds are extracted through cutting, and the average spectral reflectivity of each type of single-grain seed samples is obtained through complete image calculation, so that the credibility and the accuracy of acquired data are further improved; by utilizing the trained seed variety identification model, the variety of the extracted average spectral information of the hybrid rice seeds can be automatically judged, meanwhile, the variety of various types of hybrid rice seeds needing to be judged can be rapidly identified, meanwhile, the whole process is more rapid and convenient, and lossless judgment is achieved.

Description

technical field [0001] The invention relates to the technical field of authenticity detection of key food crop varieties, in particular to a hyperspectral-based single hybrid rice seed identification method. Background technique [0002] Rice is one of the most important food crops in my country and is the main food for nearly 50% of the world's population. The rice planting area in my country accounts for about 20% of the global planting area, and the total planting output ranks first in the world. Hybrid rice is a grain production increasing technology independently researched and developed by our country. The output of hybrid rice accounts for more than 50% of the total domestic rice production. With the continuous innovation and development of breeding technology, the development of hybrid rice in China has been leading the world. Therefore, the yield and quality of hybrid rice are of great significance to the world's agricultural and food security, so it is the long-te...

Problems solved by technology

The field identification method is an identification method recognized by most farmers, but this method takes a long time, is cumbersome to operate, and has a relatively large seasonal impact

Although chemical methods such as high performance liquid chromatography and gas chromatography have relatively accurate results and good repeatability, they are expensive, consume reagents, and require professional personnel to operate.

These methods have the disadvantages of seed damage, time-consuming and high cost, and can only be applied to a small number of samples. There is an urgent need for a simple, fast and effective new detection technology
