Brooding-before clear egg distinguishing method and device thereof

Abstract

The invention discloses a brooding-before clear egg detection device and a method thereof, belonging to the egg detection manufacturing technical field. The invention constructs an embedded clear egg distinguishing system, and hardware of the system are an ARM S3C2410 embedded system development board, a CMOS image sensor OV7620, an LED and a buzzer. The invention constructs clear egg distinguishing software by using C language and assembly language in the Linux environment provided by ARM S3C2410. The key components of the software include hatching egg acquisition, image border detection, characteristic parameter extraction and three-layer BP neural network; and the main function to be realized is that the neural network is utilized to distinguish clear egg and embryonated egg according to the characteristic parameters of the acquire image (including circularity, complexity, elongation, spherical property, axial ratio and coefficient of variation). The output of the neural network is 10 or 01, the output is taken as driving level and is displayed by the LED, and the buzzer makes a noise. By adopting the method and device, clear egg distinguishing is convenient and rapid, the requirement of rejecting clear egg before brooding can be completely met, thus the clear egg distinguishing system is efficient and practical.

Description

technical field [0001] The invention provides a device and method for identifying and detecting sperm-free eggs before hatching, and belongs to the field of technologies and methods for pre-hatching detection of breeding eggs. Background technique [0002] The hatching process of breeding eggs takes about 21 days, which requires high environmental temperature and humidity conditions, and is a time-consuming and energy-consuming process. According to statistics in the mid-to-late 1980s, about 5.97 billion eggs were hatched in the United States in 1988, and unfertilized eggs accounted for about 8% to 9% of the total hatched eggs, and it cost 3 cents to hatch each egg, which caused considerable economic losses. considerable. About 300 million eggs were hatched in Jiangsu Province of my country in 1988, and the unfertilized eggs were calculated at 8% to 9%. Only Jiangsu Province lost several million yuan. This means that a large number of unfertilized eggs cannot be hatched ev...

AI Technical Summary

Problems solved by technology

Previous studies have shown that non-destructive testing technology can be effectively applied to the detection of hatching eggs, but there are still some problems. There are no relevant reports on the detection at home and abroad, and the research is done at the laboratory level, which is still a long way from practical application
