Abstract

The invention discloses a machine vision-based automatic grading device and method for the size of a whole box of red grapes, and relates to the technical field of group fruit grading. The method is as follows: ① number the whole boxes of red grapes to be tested and place them on the conveyor belt; Image processing of images and color images: read images; preprocess images; image fusion; edge extraction; grape fruit image segmentation; remove small area processing; ellipse fitting; extract parameters; filter ellipses; establish a classification model and check. The invention utilizes machine vision technology to complete the automatic grading of a whole box of red grapes; the grading standard is unified and the grading accuracy rate is high; image processing technology is used to realize non-destructive detection, and the detection speed is fast; Large and small non-destructive testing has broad application prospects.

Description

Technical field [0001] The invention relates to the technical field of group fruit grading, in particular to an automatic grading device and a method for the size of a box of red grapes based on machine vision. The invention mainly uses an industrial camera to collect images of red grape grapes, extracts the size parameters of the red grape grapes through a series of image processing methods, establishes a model according to the size of the fruit, and tests for classification, which is the automatic classification of red grapes Provide a lossless and fast method. Background technique [0002] At present, the grading of the size of the red grape grapes is mainly achieved manually. The maximum axial diameter of the fruit is measured by measuring the maximum axial diameter of the fruit with a vernier caliper. According to the measured number of The diameter of the fruit pieces is used to determine the grade of the whole box of red fruit pieces. When grading the size of red grape g...
