Non-invasive method and device for detecting survival status of egg embryo

Abstract

The invention belongs to hatching egg screening and embryo fertility detecting technology, and particularly relates to an imaging method and an imaging device, which can detect the survival status of an embryo through a complete eggshell in a non-invasive manner in the hatching process of poultry. The imaging method comprises the following steps of: irradiating a detected hatching egg by using a near infrared laser beam as a light source; by a photoelectronic imaging system, continuously acquiring a plurality of frames of images of the hatching egg irradiated by the laser beam; for each frame of acquired image, calculating a statistic C which represents that light intensity is changed with time on the same pixel; and traversing all the pixels and finally, constructing an egg embryo fertility image by respectively using the C value corresponding to each pixel as a gray level. The device comprises the laser beam, the hatching egg, the photoelectronic imaging system and a computer. The survival status of the embryo in the egg can be monitored in a real-time, dynamic, high time resolution and high space resolution manner through the complete eggshell and the eggshell does not need to be broken or pierced. The imaging method and the imaging device have the advantages of no damage, early detection and convenience for automatically identifying fertility of the egg embryo.

Description

technical field [0001] The invention relates to breeding egg screening and embryo viability detection, in particular to an imaging method and a device thereof capable of non-invasively detecting embryo viability during poultry hatching. It is suitable for monitoring the survival status of egg embryos in the process of industrial egg incubation, and timely removes sperm-free eggs and dead embryo eggs, providing a technology for the modern hatching industry to automatically detect the life status of embryos in eggs. Background technique [0002] Each batch of traditional chicken farms hatches as many as one hundred thousand to several million eggs. Egg screening and embryo viability detection during egg incubation are important technical links in hatching work, and are the prerequisite and economic benefits for producing high-quality poultry eggs. protection. At present, the hatchery adopts the traditional method of manual candling for detection, but manual detection is labor...

AI Technical Summary

Problems solved by technology

At present, the hatchery adopts the traditional method of artificially lighting eggs for detection, but manual detection is labor-intensive, inefficient, and inaccurate, which can no longer meet the needs of modern industrialized incubation.

Moreover, the light method can only be used for head-lighting on the fifth day to pick out the sperm-free eggs.

However, after 72 hours of hatching of fresh eggs, the quality drops below Grade B, which wastes a large amount of edible eggs and increases production costs, and the infertile eggs and dead embryonated eggs that cannot be removed in time will also breed bacteria and contaminate the surrounding normal embryonated eggs

At present, non-manual detection methods such as the optical characteristics and electrical characteristics of eggs and machine vision technology cannot achieve earlier detection.
