Embodiment Construction

[0027] The edible fungus cleaning production line sends edible fungi of different specifications (flammulina velutipes, straw mushrooms, oyster mushrooms, etc.) through ultrasonic cleaning, ozone sterilization, decolorization and bleaching to the edible fungi impurity online identification system of the present invention. Edible mushrooms are placed horizontally on the production line, and the moving speed of the production line is about 24 m / min.

[0028] Such as figure 2 As shown, the edible fungus impurity online identification system also includes a lighting system, a CCD camera, an image acquisition card, and an industrial computer. Among them, the lighting system adopts a special lighting source for image processing, and adopts a shadowless uniform diffusion lighting method. The digital camera sensor adopts 2 / 3″ color area array CCD, equipped with a 5 megapixel lens, the distance between the lens and the detection target is 20cm to 30cm, and the field of view is 50mm×5...

Abstract

The invention provides a system for identifying impurities of edible funguses on line. The system comprises an edible fungus cleaning production line on which a lighting device and a digital camera are arranged, an image acquisition card, an industrial personal computer and the like, wherein the digital camera is arranged above the outlet of an output device of the edible fungus cleaning production line, and comprises a plurality of camera lenses; images shot by the camera lenses are sent into the industrial personal computer through the image acquisition card are processed and subjected to impurity identification; and therefore, a plurality of impurities such as hairs, silk wadding shells, woven bag lines, mulching film fragments and the like in the edible funguses can be identified and detected.

Description

technical field [0001] This application relates to an online recognition system for impurities in agricultural products, in particular to an online recognition system for edible fungus impurities using machine vision technology. Background technique [0002] In the agricultural product processing industry, from the grading and screening of raw materials to the baking during processing, impurity monitoring, finished product portioning, and finished product quality inspection, there are applications of machine vision technology. There are a wide variety of agricultural products, ranging from vegetables, fruits to meat, with different specifications and ever-changing changes. It is challenging to automatically classify, detect, analyze and process such products with machine vision technology. For various specific problems, researchers from various countries have proposed numerous modeling and identification methods. Tao et al. (1995) successfully developed the Merling high-spe...
