Abstract

The invention realizes fruit sorting on two aspects such as hardware design and model selection and software system development by using a machine vision technology, and comprises the steps of designing and selecting a machine vision industrial camera, a lens and a lighting scheme to ensure the fruit sorting system to continuously and steadily obtain a high-quality fruit image; suppressing salt-and-pepper noise and Gaussian noise in the fruit image by using median filtering and binomial filtering; highlighting edge information of the fruit image by adopting an anti-sharpening mask method at the same time; realizing fruit classification by adopting a supervised Gaussian mixture model clustering algorithm; and calibrating data grasped by a robot guided by a monocular camera through a Zhang Zhengyou calibration method, and calculating the actual grasping position and pose.

Description

technical field [0001] This system is the application of machine vision in fruit sorting, which belongs to the field of image processing and machine vision, involves Halcon software, and specifically involves the classification, grading and sorting of fruits. Background technique [0002] In the past two decades, machine vision technology has been developed to a greater extent, especially in industrial and agricultural production, which has gradually shown the trend of replacing manual high-risk, high-intensity, repetitive and complicated work. This mainly depends on the unique advantages shown by machine vision. First of all, machine vision technology adds visual non-contact sensors to industrial production lines, which improves the flexibility of production from the side. Secondly, the visual image carries a large amount of production information, and the desired production data can be obtained in a non-contact manner through the analysis of the target image. Finally, th...
