Embodiment Construction

[0045] The present invention aims at proposing an automatic detection method for the quality of unstrained spirits in the liquor brewing process, and solves the problem that the detection and evaluation of unstrained spirits in the traditional technology in the process of liquor production relies on manual experience, has large errors and poor reproducibility . The core idea is: by collecting the image of the fermented grains to be tested, and using the real-time foreground extraction algorithm to obtain the region of interest; then, obtain the color features and texture features of the image, and use the improved maximum between-class variance method combined with connected domain filtering to calculate The size index of the material is calculated by wavelet texture analysis; the water content of the fermented grains is estimated by partial least squares regression analysis combined with color features, which balances speed and accuracy; the characteristic variables of ferment...

Abstract

The invention relates to the white spirit making field and the image processing field, discloses an automatic detection method for fermented grain quality in the white spirit making process, and solves the problems that in the white spirit production process, the traditional technology depends on artificial experience in detection and evaluation of fermented grains, has large error and poor reproducibility. The method comprises the following steps of: A, establishing a fermented grain quality evaluation model based on an adaptive fuzzy inference algorithm; B, training a fermented grain qualityevaluation model based on fermented grain samples with known quality grading and corresponding grading results; and C, detecting to-be-detected fermented grains by adopting the trained fermented grain quality evaluation model. The method is suitable for automatic detection and evaluation of the fermented grain quality in a grain preparation link in a full-automatic white spirit making process.

Description

technical field [0001] The invention relates to the fields of liquor brewing and image processing, in particular to an automatic detection method for the quality of grains in the liquor brewing process, which is suitable for automatic detection and evaluation of the quality of grains in the grain mixing link in the fully automatic liquor brewing process. Background technique [0002] my country is a big liquor producing country with a long history. The traditional liquor production method is mainly manual operation. With the advancement of technology, large-scale liquor factories have basically realized mechanization, which greatly reduces the labor intensity of workers and improves the production efficiency of liquor. Although a few large-scale liquor companies have achieved automation in some parts of the process, such as mixing ingredients, fermentation, and steaming wine, they have not yet realized the automation of the entire process of liquor production. The implement...
