Embodiment 1

[0017] Take 200 fresh grass eggs and measure their maximum major axis diameter with a digital display vernier caliper L , use an electronic balance to measure the mass m of the poultry egg; use an electronic balance to measure the mass m of the supporting point 1 ; Fix the special support parts to the end points of 200 grass eggs with glue, then place 200 grass eggs on the special support frame respectively, and keep the support level, and measure the quality m of the support point by electronic balance 1 ; Use the formula to calculate the distance J from the center of mass to the endpoint of the small end. The average centroid position of 200 grass eggs is 26.52±1.52 (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

[0019] Take 200 foreign eggs and measure their maximum major axis diameter with a digital display vernier caliper L , use an electronic balance to measure the mass m of the poultry egg; use an electronic balance to measure the mass m of the supporting point 1 ; Fix the special support parts to the end points of the big and small ends of 200 foreign eggs with glue, then place the 200 foreign eggs on the special support frame respectively, and keep the support level, measure the quality m of the support point by electronic balance 1 ; Use the formula to calculate the distance J from the center of mass to the endpoint of the small end. The average centroid position of 200 foreign eggs is 27.61±1.60 (mm), which is the same as the maximum major axis diameter L The ratio is 0.48±0.02 (the center of mass of foreign chicken eggs is approximately at the midpoint of its long diameter).

Embodiment 3

[0021] Take 200 fresh duck eggs and measure the maximum major axis diameter with a digital display vernier caliper L , use an electronic balance to measure the mass m of the poultry egg; use an electronic balance to measure the mass m of the supporting point 1 ; Fix the special support piece on the end points of the big and small heads of 200 duck eggs with glue, then place 200 duck eggs on the special support frame respectively, and keep the support level, measure the quality m of the support point by electronic balance 1 ; Use the formula to calculate the distance J from the center of mass to the endpoint of the small end. The average centroid position of 200 duck eggs is 28.20±1.80 (mm), which is the same as the maximum major axis diameter L The ratio is 0.48±0.02 (the center of mass of the duck egg is approximately at the midpoint of the long diameter of the egg).

Abstract

The invention relates to a fowl egg mass center detecting method, which belongs to the technical field of object characteristic parameter detection. The method comprises the following steps of: first, measuring maximum long axis diameter L of a fowl egg; weighing mass m of the fowl egg; fixing a special supporting piece at both big and small end points of the fowl egg by glues, wherein axis directions of the special supporting pieces are coincided with extension line of the maximum long axis diameter of the fowl egg; respectively placing the special supporting pieces on special supporting frames; keeping the supports in a horizontal state, wherein one special supporting frame is placed beyond a balance while the other special supporting frame is placed on an electronic balance; detecting mass m1 of the supporting point by the electronic balance; and calculating a distance J between mass center distance of the fowl egg and the small end point, wherein the calculation formula is J=Lm1/m. The fowl egg mass center detecting method 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, and belongs to the technical field of measuring object characteristic parameters. 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 and a quality prediction model; in the field of egg breed selectio...
