Mechanical vision fruit classifying system controlled by shift register

Abstract

A fruit classification system with mechanical vision controlled by shift register is composed of an external power unit, a delivery unit and a classifying unit which are composed of two chain wheels and chain, an encoder installed on the delivery unit, an image acquisition card in computer, an illuminating box, a camera in the illuminating box, a computer, a shift register set connected to the computer and the classifying unit, a discharge port, and a software. Its advantages are no destruction to fruit.

Description

technical field [0001] The invention relates to a machine vision fruit grading system controlled by a shift register. Background technique [0002] At present, the level of post-harvest treatment of fruits in my country is still very low. Most fruits are directly listed without post-harvest treatment after picking, which affects the commodity value of fruits. There are also some fruits that are manually and visually identified and judged according to the grading indicators such as their maturity, surface defects, fruit stem integrity, size, and weight. Therefore, the classification of fruits is relatively subjective, and the efficiency is quite low. It hinders the development of my country's national economy and the improvement of farmers' income. The existing fruit grading equipment mainly uses one or two indicators such as the weight and size of the fruit. The former mainly uses sieve holes, roller gaps, etc., and the latter mainly uses electro...

[0002] At present, the level of post-harvest treatment of fruits in my country is still very low. Most of the fruits are directly listed without post-harvest treatment after picking, which affects the commodity value of fruits.

There are also some fruits that are manually and visually identified and judged according to the grading indicators such as their maturity, surface defects, fruit stem integrity, size, and weight. Therefore, the classification of fruits is relatively subjective, and the efficiency is quite low. It has hindered the development of our country's national economy and the improvement of farmers' income

The existing fruit grading equipment mainly uses one or two indicators such as the weight and size of the fruit. The former mainly uses sieve holes, roller gaps, etc., and the latter mainly uses electronic scales and force balance brackets for grading equipment. , this type of equipment cannot grade fruits with surface defects and unique fruit shapes, and there are deficiencies such as easy damage to the surface of fruits during the grading process
