Machine vision selection device and method for infertile eggs in whole tray of hatching duck eggs

Abstract

The invention discloses a machine vision selection device and method for infertile eggs in whole tray of hatching duck eggs. The machine vision selection device comprises a crawler-type conveying belt, the crawler-type conveying belt is in driven connection with a first motor, a light chamber is arranged in the center of the crawler-type conveying belt, an egg tray is placed on the crawler-type conveying belt, a plurality of hatching duck eggs hatched for 5 days are vertically placed in the egg tray, a whole tray egg suction device is arranged in the light chamber, the whole tray egg suction device is connected to the inner side wall of the light chamber in a sliding mode, an image acquisition mechanism is arranged on the light chamber, the image acquisition mechanism is in signal connection with a control mechanism, the image acquisition mechanism is used for acquiring images of the whole tray of hatching duck eggs and identifying infertile eggs and fertile eggs for the hatching duckeggs, the control mechanism is used for controlling the whole tray egg suction device to move and grab hatching duck eggs belonging to the infertile eggs, and the whole tray egg suction device is usedfor grabbing the hatching duck eggs on the egg tray. According to the machine vision selection device and method, the problem that the automation degree and the intelligent degree of the poultry egghatching industry are low can be practically solved.

Description

technical field [0001] The invention relates to the technical field of on-line non-destructive automatic detection and selection of agricultural products, in particular to a machine vision selection device and method for non-sperm eggs in a whole plate of breeding duck eggs. Background technique [0002] According to the data provided by the China Animal Husbandry Association and the World Food and Agriculture Organization (FAO) in 2018, the world's meat ducks are about 4.74 billion, and the laying ducks are about 187 million. my country's duck breeding accounts for 74.3% of the world's duck breeding. This shows that my country's duck egg hatching industry needs to hatch billions of ducklings every year to meet domestic breeding needs. However, at present, domestic duck breeding methods are mainly based on free-range breeding, resulting in a natural fertilization rate of duck eggs lower than 80% (Li Qingxu, 2020, Journal of Agricultural Mechanics). At present, in my country...
