Grapefruit quality sorting method based on visual technique

Abstract

The invention discloses a grapefruit quality sorting method based on a visual technique. To-be-sorted grapefruit enters a weighing platform (10.1) of a detection platform through a feed mechanism (8),whether the to-be-sorted grapefruit is in a vertical state is detected through an upper camera (4.1), if the to-be-sorted grapefruit is not in the vertical state, the position of the to-be-sorted grapefruit is adjusted to the vertical state by a positioning push mechanism (7), the to-be-sorted grapefruit is weighed by the weighing platform (10.1), the weighing platform (10.1) is rotatably arranged, the weighing platform (10.1) rotates so as to drive the to-be-sorted grapefruit to rotate, and the to-be-sorted grapefruit is continuously shot by a side camera (4.2) at the same time, so that thesize of the to-be-sorted grapefruit is obtained, the density of the to-be-sorted grapefruit is obtained according to the obtained weight and size, and the to-be-sorted grapefruit is pushed into corresponding discharge channels (1) by the positioning push mechanism (7) according to the density of the to-be-sorted grapefruit, so that quality sorting is realized.

Description

technical field [0001] The invention relates to the technical field of fruit quality sorting, in particular to a visual technology-based grapefruit quality sorting method. Background technique [0002] Grapefruit is a fruit that people like very much. It is fragrant, sweet and sour, cool, rich in nutrition and has high medicinal value. But when people buy grapefruits, they can only choose grapefruits with sufficient juice by feeling (weigh them with your hands, if they feel heavier, it means enough water), but this kind of empirical selection is often less accurate. When picking pomelo, one cannot distinguish by size. For the same batch of pomelo (same variety, same place of origin, same picking period, same transportation and storage method), use the comprehensive indicators of density, size, weight, and shape to judge the quality of pomelo. more precise grading. The higher the density, the more abundant the water content. Of course, in addition to consumers' selection o...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims at the technical problems of low pomelo sorting accuracy and low sorting efficiency in the above-mentioned prior art, and provides a pomelo quality sorting method based on vision technology that can be accurately and automatically sorted
