Problems solved by technology

[0005] The function of the fruit hyperspectral imaging non-destructive testing device is relatively simple. It only detects a certain kind of fruit, and cannot perform non-destructive testing on different fruit types and different varieties of fruits, and cannot realize different light source numbers, different light source incident angles, and different detection hole diameters. change

Abstract

The invention discloses a nondestructive testing device for hyperspectral transmission imaging of sphere-like fruits and relates to the technical field of nondestructive testing of agricultural product quality. The device is characterized in that a motorized translation stage (40) is arranged at the bottom in a box body (20), a sample chamber (50) is formed in the upper part of the motorized translation stage (40), and a hyperspectral imaging instrument (30) is arranged at the top in the box body (20); the motorized translation stage (40) and the hyperspectral imaging instrument (30) are connected respectively with a computer (10) outside the box body (20); a fruit sample (00) is arranged in the sample chamber (50) and aligns to the hyperspectral imaging instrument (30). The device is reasonable in design and convenient to adjust, has comprehensive functions and is applicable to nondestructive detection and experimental research of the sphere-like fruits such as apples, persimmons, pears, peaches, oranges, watermelons and the like.

Description

Technical field [0001] The invention relates to the technical field of non-destructive detection of agricultural product quality, in particular to a non-destructive detection device for spherical fruit transmission hyperspectral imaging. Background technique [0002] With the continuous improvement of domestic and foreign fruit consumption demand and taste, the market has put forward more and higher requirements on the quality of fruits. When buying fruits, not only pay attention to the external qualities such as the size and appearance of the fruit, but also pay more attention to the internal qualities of the fruit such as taste, sugar content and nutritional content. China's fruit planting area and output have ranked first in the world for many years. The fruit industry occupies a large share of domestic agricultural and sideline products. It has become a pillar industry for China's local economic development and farmers' income, and it has greatly promoted the development of l...
