Description

Technical Field

[0001] The utility model relates to the technical field of spectrum collection, in particular to a dynamic citrus spectrum collection device. Background Art

[0002] As a major citrus producer, China ranks first in the world in both annual citrus production and citrus planting area. Citrus is rich in a variety of nutrients needed by the human body. With the increase in urban and rural residents' income and the upgrading of consumption concepts, consumers are paying more and more attention to the quality of citrus. At the same time, according to the quality of citrus, graded sales can be achieved to maximize the income of fruit farmers.

[0003] At present, the existing citrus quality detection methods in China are mostly manual detection, chemical detection, and machine vision detection, but they all have different problems. Manual detection depends on the experience of the detector, the test results are subjective and the accuracy is not high. Chemical detection is a destructive test. Although it can accurately detect the quality of citrus, the citrus cannot flow into the consumer market after detection. The machine vision detection method is mainly based on the detection of citrus appearance information, and it is impossible to deeply detect the quality of the citrus inside. The visible near-infrared detection method irradiates citrus with visible near-infrared light. There are differences in the internal quality of different citrus, so the degree of transmission of visible near-infrared light is different, that is, the quality difference is reflected in the visible near-infrared spectrum, and then the citrus quality information is extracted from the spectrum, and the internal quality of citrus can be detected. Therefore, visible near-infrared spectral detection has gradually begun to be applied to the field of citrus detection, but the current spectrum acquisition devices are mostly static acquisition, which cannot meet the requirements of assembly line citrus quality detection. And it is necessary to change the spot size according to the different sizes of citrus to realize the collection of its visible near-infrared spectrum. Utility Model Content
