Online image acquisition system for detecting citrus skin defects and method

Abstract

The invention relates to an online image acquisition system for detecting citrus skin defects and a detection method. The system comprises ultraviolet light detection equipment, visible light detection equipment and light blocking shells, wherein the light blocking shells are arranged outside the ultraviolet light detection equipment and the visible light detection equipment; the citrus sequentially passes through the ultraviolet light detection equipment and the visible light detection equipment; the ultraviolet light detection equipment is used for irradiating ultraviolet light to the citrus skin, so that the citrus corruption region generates yellow fluorescence and acquires fluorescence images of different positions in a citrus rotation state in real time; the visible light detection equipment is used for irradiating visible light to the citrus skin and acquiring color images of different positions when the citrus rotates; the light blocking shells are used for preventing stray light from entering when the citrus passes through the ultraviolet light detection equipment and the visible light detection equipment. The detection method is realized on the basis of the online image acquisition system. The online image acquisition system and the detection method provided by the invention can rapidly identify fruit with skin defects, can reduce the working intensity of workers, and enhances the competitiveness of the products.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an online image acquisition system and method for citrus fruits with skin defects. Background technique [0002] Citrus has a unique flavor and rich nutrition, and is favored by consumers. The total output of citrus in my country is very large, but most varieties are sold at low prices in China, and the problem of "difficulty in selling fruit" often occurs, which restrains the development momentum of the citrus industry. One important reason is that post-harvest commercialization is lagging behind. The appearance quality is poor, resulting in weak market competitiveness of the fruit. [0003] According to the trend of fruit production and sales, it can be found that most of the fruit output value is created by post-harvest processing and post-harvest processing. Post-harvest commercialization of fruits includes cleaning, waxing, sorting, and packaging. At present, the clea...
