Fruit and vegetable surface damage detecting device based on hyperspectrum

Abstract

The invention discloses a fruit and vegetable surface damage detecting device based on hyperspectrum. The device comprises a hyperspectral scanning system, a fruit and vegetable rotating system and a fruit and vegetable conveying system, wherein the hyperspectral scanning system is arranged above the fruit and vegetable rotating system; the fruit and vegetable conveying system comprises a fruit and vegetable inputting track and a fruit and vegetable outputting track; the fruit and vegetable inputting track is arranged above the fruit and vegetable rotating system; the fruit and vegetable outputting track is arranged below the fruit and vegetable rotating system; the fruit and vegetable rotating system comprises an air cylinder, a first motor, a second motor, a first roller and a second roller; the first roller and the second roller are located in the same horizontal plane; the first roller is connected with the first motor and the air cylinder; the second roller is connected with the second motor; the air cylinder is used for controlling the first roller to get far away or get close to the second roller. The device disclosed by the invention has the advantages that all spectral images of the surfaces of to-be-detected fruits and vegetables can be obtained; a blind spot is avoided in the food detecting; misjudgment in the food grading is reduced.

Description

Technical field [0001] The invention relates to the field of food quality detection, in particular to a hyperspectral-based fruit and vegetable surface damage detection device. Background technique [0002] Fruits and vegetables are indispensable foods in the lives of residents. Most of them require long-distance transportation. During transportation and storage, if the fruits and vegetables that will fester are not cleaned up in time, it will cause other fruits and vegetables around to fester quickly. Therefore, rapid detection and separation as soon as possible are required. However, traditional food inspections are mostly manually selected by inspectors, which is time-consuming, laborious and inefficient. Therefore, the development of a fast, non-destructive and accurate automatic detection technology has become an urgent need. With the advancement of science and technology, hyperspectral, as an emerging non-destructive testing technology, combines spectroscopy and imaging t...
