Device and method for recognizing hatching egg incubation based on hyperspectrum

Abstract

The invention discloses a device and a method for recognizing hatching egg incubation based on hyperspectrum and belongs to the technical field of detection of agricultural products. The method comprises the following steps of: acquiring a hyperspectral image in the whole incubation process through a hyperspectral imager, analyzing the difference between different types of hatching egg images and the spectrum, extracting corresponding image and spectrum characteristic parameters, and optimizing a variable set which reflects the hatching egg incubation characteristics on the basis. According to the actual production conditions, a hierarchical support vector machine classifier based on a decision-making tree type is designed, and a hatching egg incubation determination model is established. According to the method, infertile eggs, eggs with abnormal early embryonic development, scattered yellow eggs, middle dead embryonic eggs and later-stage dead embryonic eggs are accurately recognized, an effect of monitoring the incubation process is achieved, manual detection can be completely replaced, and the method has significance and application values for improving the automation level of detecting the national poultry incubation quality.

Description

technical field [0001] The invention relates to a device and method for identifying egg hatching based on hyperspectral, and belongs to the technical field of agricultural and livestock product detection. Background technique [0002] Poultry eggs contain protein, fat, minerals and multivitamins needed by the human body, are easy to digest and absorb, have high nutritional value, and are the most ideal natural food known to mankind. my country is rich in poultry egg resources and diverse in variety, and is the world's largest poultry egg production and consumption country. According to incomplete statistics, the total output value of my country's egg industry has reached 160-200 billion yuan, which occupies a high proportion in the national economy. By 2006, my country's poultry egg output reached more than 29.6 million tons, accounting for about 46% of the world's total output. In 2007, my country's poultry egg output reached about 31 million tons. Over the past few years,...

Problems solved by technology

Although there are many studies on the detection of hatching viability, most of these studies only involve the early stage (4-6 days). There are very few studies on the viability of hatching egg embryos throughout the hatching stage, and few use hyperspectral imaging technology to conduct comprehensive research. Research; and the research mainly focuses on white-shell eggs, and rarely involves the detection of brown-shell eggs in the early stage of hatching, and there are problems such as low detection accuracy of brown-shell eggs in the early stage of hatching.
