Fruit internal quality detection method and system

Abstract

The invention provides an internal quality detection method and system for fruit. The method includes: emitting incident light being monochrome continuous near-infrared light into to-be-measured fruit; according to light intensity information of the incident light and light intensity information of emitted light corresponding to the incident light, acquiring light intensity change information; according to the light intensity change information, acquiring an absorption coefficient and a scattering coefficient of the to-be-measured fruit; and on the basis of the absorption coefficient and the scattering coefficient, acquiring the internal quality of the to-be-measured fruit. According to the internal quality detection method and system for fruit, the to-be-measured fruit are irradiated by using the monochromatic continuous near-infrared light; because of the light absorption and scattering in the internal tissue of the fruit, the intensity of the emitted light will exist attenuation with the certain degree; the light intensity of the emitted light is detected and the absorption coefficient and scattering coefficient of the tissue are calculated, so that the internal quality of the to-be-measured fruit is obtained. According to the method, adjustment of the frequency of the light source is avoided; and the equipment is simple and the detection speed is fast.

Description

technical field [0001] The invention relates to the field of inspection and detection of agricultural products, in particular to a method and system for detecting the internal quality of fruits. Background technique [0002] In recent years, the world's fruit industry has developed rapidly. At present, the world's total fruit output exceeds 630 million tons per year. As the world's largest fruit producer and consumer, the development of the fruit industry is crucial to ensuring domestic market supply, increasing farmers' income, and improving the ecological environment. It is of great significance to promote rural economic development. Especially, along with the raising of people's living standard, also more and more strict to the quality requirement of fruit. However, the general method can only judge the quality of the fruit through the external characteristics of the fruit, but cannot observe the hidden defects inside the fruit. Therefore, it is particularly important to...
