Green Chinese onion three-grain plug seedling miss-seeding detection method and reseeding device

Abstract

The invention relates to a green Chinese onion three-grain plug seedling miss-seeding detection method and a reseeding device. The reseeding device comprises a hole pressing device and a drum-type seeding device which are arranged on a workbench, and an image recognition device, a needle-type reseeding device and a conveying belt which are arranged on the workbench, wherein the conveying belt is used for driving a plug to move. The hole pressing device, the drum-type seeding device, the image recognition device and the needle-type reseeding device are sequentially arranged along the moving direction of the plug. The miss-seeding condition of plug holes is recognized through the image recognition device, and the recognition accuracy is improved. A photoelectric sensor is mounted to determine the information of the position passing through the plug, so that accurate position information support is provided for the needle type reseeding device; mutually independent seed suction heads arearranged on a seeding rod, and air suction and air outlet of an electromagnetic valve are utilized, so that reseeding operation is carried out on each plug hole in the plug, the reseeding accuracy isimproved, and the reseeding reliability is also improved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a machine vision-based method for detecting missing sowing of scallion three-grain plug seedlings and a replanting device. Background technique [0002] Scallions are one of the important economic crops in my country, and the planting area and output of scallions in my country rank first in the world. Green onion seedling cultivation is the most basic link in the production of green onions, and it is also the most important link. [0003] There are two main ways to raise seedlings for scallions: one is traditional artificial seedling raising, and the other is special mechanical seedling raising. The labor cost of artificial seedlings is too high, the labor intensity is high, and the emergence quality of artificial seedlings is poor, which is not conducive to subsequent mechanized transplanting. The sowing of mechanical seedlings basically adopts the...
