Abstract

The invention relates to the technical field of machine vision detection, in particular to a machine vision-based online damage identification and classification device for corn seeds. Including feeding device, conveying device, image acquisition device, classification device, control system, fixed-axis test bench, and recovery seed box. Its features are as follows: through the online damage identification and classification device of corn seeds, it can collect dynamic images and realize the dynamic detection function of online damage identification of corn seeds, and separate the damaged corn seeds from qualified corn seeds; a simple structure of the rotary table transmission mechanism is designed; A mechanism for removing unqualified corn seeds is designed, which can accurately and effectively remove unqualified corn seeds; an online damage identification and classification control system for corn seeds is designed; the invention has simple structure, accurate identification and classification, high efficiency and good effect. The fully automated online real-time detection of corn seeds can make the detection of agricultural products more mechanized, automated and intelligent.

Description

technical field [0001] The invention relates to the technical field of machine vision detection, in particular to a machine vision-based online damage identification and classification device for corn seeds. Background technique [0002] As one of the important food crops in my country, corn has become the largest food crop in my country since 2012 and has a very important strategic position. Because corn seeds will be damaged by various factors such as mechanical damage during harvesting and storage, which directly affects the germination rate of corn seeds and corn yield, so the damage detection of corn seeds before sowing is essential. This process can ensure the germination rate of corn seeds, which is of great significance to the increase of corn yield. [0003] Compared with manual inspection technology, machine vision inspection technology has the advantages of fast speed, high precision, and good repeatability, and has broad applications in the field of non-destruct...
