Embodiment Construction

[0038] The fruit sorting device and chestnut sorting method proposed by the present invention are described as follows in conjunction with the accompanying drawings and embodiments.

[0039] The fruit sorting device in this embodiment is applied to chestnut sorting. Because the color of chestnut is darker, it is very difficult to distinguish the color of its mildew and insect eyes, and the characteristic size of defects is smaller. Therefore, it has great advantages for the sorting of chestnut specificity and complexity.

[0040] The chestnut sorting device of this embodiment includes: a frame 1, a drive unit, a conveying unit, an image acquisition and processing unit, and a sorting control unit 4, wherein the frame 1 adopts an angle steel profile welding structure for supporting the whole device.

[0041] Such as figure 1 As shown, the driving device includes: a driving motor 16, which is connected with the sorting control unit 4, is an AC geared motor, can be steplessly adj...

Abstract

The invention relates to a fruit sorting device, which comprises a machine frame, a driving unit, a conveying unit, an image acquisition and processing unit, a sorting control unit, and a separating unit. The sorting control unit controls the driving unit to drive the conveying unit so as to convey fruits to the area of the image acquisition and processing unit which acquires the image information on the fruits, shoots a plurality of images containing effective information of the fruits, and judges the comprehensive quality of the images through a computer vision technique; and the sorting control unit tracks, detects and finally separates out the bad fruit so as to achieve the fruit sorting. The device adopts non-touch type judgment and has the advantages of simple structure, low price, and accurate and objective analysis.

Description

technical field [0001] The invention relates to the field of agricultural engineering, in particular to a machine vision-based fruit sorting device and a chestnut sorting method. Background technique [0002] Fruits are graded and classified according to their quality and then enter the market for circulation, which facilitates price discussions based on quality, improves their market competitiveness and commodity value, and increases farmers' income. At present, the post-grading technology of fruit collection is developing from mechanical size, weight grading and human visual identification quality to quality grading based on machine vision, such as the Optiscan II high-speed small fruit grading production line of French MAF-RODA company, China Agricultural The computer vision fruit grading automation system developed by the university, etc. [0003] At present, the application objects of detection and grading based on machine vision mainly include apples, citrus, peaches,...
