Embodiment 1

[0023] Take 200 fresh grass eggs, and measure the average major axis diameter of 200 grass eggs L 54.25±2.16, the average centroid position away from the small end J It is 26.66±1.40 (mm), which is the same as the maximum major axis diameter L The ratio is 0.49±0.02 (the centroid of the grass egg is approximately at the midpoint of its long diameter).

Embodiment 2

[0025] Take 200 fresh foreign eggs, and measure the average major axis diameter of 200 foreign eggs L is 57.21±2.56, the average centroid position away from the small end J It is 28.24±1.43 (mm), which is the same as the maximum major axis diameter L The ratio is 0.49±0.03 (the center of mass of the foreign egg is approximately at the midpoint of its long diameter).

[0026]

Embodiment 3

[0028] Take 200 fresh duck eggs, and measure the average major axis diameter of 200 duck eggs L is 58.89±2.76, the average centroid position away from the small end J It is 28.47±1.76 (mm), which is the same as the maximum major axis diameter L The ratio is 0.48±0.04 (the center of mass of the duck egg is approximately at the midpoint of its long diameter).

Abstract

The invention provides a fowl egg mass center detecting method based on an image, in particular a fowl egg mass center detecting method, which belongs to an object physical parameter detecting method. The method comprises the following steps of: shooting an image of a fowl egg when being placed in the horizontal plane in a balanced way by using a digital camera; analyzing the image by using a drawing software in WINDOWS system; and figuring out the position of the mass center of the fowl egg. The fowl egg mass center detecting method based on the image, provided by the invention, can be applied to dynamics analysis and fowl egg freshness detection in fowl egg grading treatment.

Description

technical field [0001] The invention relates to a method for measuring the center of mass of an object with a non-standard geometric shape, in particular to a method for measuring the center of mass of an egg, which belongs to the method for measuring the physical parameters of the object. Background technique [0002] The centroid is the basic characteristic parameter of poultry eggs and the basic parameter of dynamic analysis in the automatic grading process of poultry eggs. At present, the research on the basic characteristics of poultry eggs, in the field of automatic grading of poultry eggs, many scholars have carried out research on poultry egg size grading models and quality models based on image processing technology, such as Wang Qiaohua and Xiong Lirong established duck eggs and egg size grading models, Zhou Ping Established a computer vision-based calculation method for egg volume and surface area, a quality prediction model, and a calculation method for egg volum...
