Egg gender detection system based on multi-mode information fusion Technical Field The invention belongs to the field of agricultural product detection, and particularly relates to an egg gender detection system based on multi-mode information fusion. Background In the large-scale poultry farming industry, sex screening of hatching eggs is a vital front link. For laying hen breeding, the male hatching eggs cannot lay eggs after hatching, so that a large amount of hatching resources, feed resources and site resources are wasted. For broiler breeding, the growth speed and feed conversion rate of broiler chickens with different sexes are different, and the screening in advance can realize group breeding and improve breeding efficiency. Therefore, sex detection before hatching egg hatching has important significance for reducing the culture cost and improving the industrial economic benefit. Some methods for detecting the sex of hatching eggs, such as an acoustic detection method, an optical detection method, a near infrared spectrum detection method and the like, are presented in the related technical field. However, individual differences of hatching eggs (such as eggshell thickness, in-egg air chamber size and the like) can interfere detection signals, the single information dimension detection method is weak in anti-interference capability, limited in detection accuracy and difficult to adapt to complex actual cultivation scenes. In addition, the detection environment of the existing detection equipment is lack of effective control, and the acquisition accuracy of sensing signals is easily affected by external interference factors such as illumination, temperature and vibration, so that the detection accuracy is further reduced.
