Rapid modeling method for detecting sugar content of navel orange based on spectral peak area in high spectral transmission technology

Abstract

The invention discloses a rapid modeling method for detecting the sugar content of a navel orange based on the spectral peak area in a high spectral transmission technology, and relates to the technical field of nondestructive detection of the fruit internal quality. The rapid modeling method comprises the following steps: (1) obtaining semi-transmissive hyperspectral patterns of a navel orange sample; (2) detecting the sugar content of the navel orange sample according to a chemical method; (3) selecting the average hyperspectral pattern of the navel orange sample; (4) calculating the spectral peak area of the average hyperspectral pattern; (5) establishing a sugar content predictive model for the navel orange sample, and utilizing the model for quality detection. The rapid modeling method has the advantages that the hyperspectral patterns of the navel orange sample are acquired in a semi-transmissive manner based on the high spectral transmission technology, so that the internal quality information of the navel orange sample can be effectively obtained, and the detection level and the detection efficiency for the fruit internal quality can be improved; the rapid modeling method is high in modeling efficiency, accuracy and model calculation speed, and can be utilized for rapidly detecting the sugar content and other indexes of the fruit internal quality, and then evaluating the fruit internal quality.

Description

technical field [0001] The invention relates to the technical field of non-destructive detection of fruit quality, in particular to a rapid modeling method for navel orange sugar detection based on the spectral peak area of ​​hyperspectral transmission technology. Background technique [0002] my country is a big fruit producing country, and its output ranks first in the world all the year round, accounting for about 19% of the world's total fruit output. The fruit industry is developing rapidly, showing an upward trend every year. The fruit industry has developed into a pillar industry for farmers in many parts of our country to generate income, and it has greatly promoted and developed agriculture and the economy. Although my country is a large fruit producing country, the overall export volume is still very small, and it is not a strong country in fruit trade. Citrus fruit is the largest fruit in the world. my country's citrus production ranks third among countries in th...

Problems solved by technology

However, for thick-skinned navel oranges, it is difficult to obtain internal information, and the data volume of hyperspectral image information is large, which increases the difficulty and time of data processing
