Abstract

The invention relates to a machine vision-based fruit sorting system and an image recognition method thereof, and belongs to the technical field of machine vision and mechanical design and control. Asystem device comprises an image collecting device, a conveying device, a robot support frame, a delta robot and a pneumatic fixture. The image collecting device is arranged above the conveying device, the delta robot is arranged behind the image collecting device through the robot support frame, the pneumatic fixture is connected with the delta robot, all parts cooperate with each other, image information is collected and uploaded to a computer for analysis and calculation, and the position coordinates of a defective fruit are obtained. Finally, the computer controls the delta robot to drivethe pneumatic fixture to clamp the fruit and put the fruit on a corresponding conveyor belt to complete the sorting process, and the recognition accuracy efficiency is high.

Description

technical field [0001] The invention relates to a fruit sorting system based on machine vision and an image recognition method thereof, belonging to the technical fields of machine vision and mechanical design and control. Background technique [0002] my country is a typical large agricultural country, and the output of crops and fruits is increasing year by year. For a long time, my country has relied on manual fruit sorting, which has resulted in high costs, low efficiency, and widely varying sorting standards, which will eventually lead to high fruit prices and difficult fruit quality to meet consumer needs. These problems have restricted the development of our agricultural economy to a certain extent. In recent years, the development of machine vision and robot technology has been relatively mature, and its application in the industrial field has become more and more extensive. It can also play its value in the agricultural field. Therefore, this invention proposes to c...
