Abstract
The invention relates to a method for calculating a volume and mass of an egg on the basis of a line of apsides, which belongs to the calculation field of object physical parameters. The method comprises the steps of: firstly measuring a maximal long axis diameter L and a maximal short axis diameter B of an egg, and estimating the volume V of the egg by utilizing a standard ellipsoid volume calculation formula (PhiLB2/6); and estimating the mass m (RhoV) through the estimated volume, wherein Rho represents a density of the egg, and the density of an ordinary egg is 1.1/cm<3>. According to the method, the volume of non-standard ellipsoidal egg is estimated by directly utilizing the standard ellipsoid volume calculation formula, so that fewer measuring parameters are involved, and the calculation method is simple; the standard ellipsoid volume calculation formula is similar to a sphere volume formula, so that the standard ellipsoid volume calculation formula is direct and clear for estimating the volume of the egg and is convenient to memorize; an egg volume model and an egg mass model based on a computer image processing technology can be favorably simplified, the calculation amount can be reduced, and simultaneously the throughput can be estimated; the kinetics analysis of a middle egg in staged treatment and establishment of a model can be facilitated; and the packaging design of the egg can be favored.
Description
Technical field
The present invention relates to a kind of volume and Mass Calculation method of irregularly shaped object, particularly a kind of birds, beasts and eggs volume and Mass Calculation method based on the line of apsides belong to the computing field of object physical parameter.
Background technology
The birds, beasts and eggs volume is its essential characteristic parameter, is the basic parameter of quality testing and dynamic analysis in the automatic hierarchical processing of birds, beasts and eggs, also is the basic parameter of birds, beasts and eggs package design.At present; The research of birds, beasts and eggs essential characteristic; In the automatic classification of birds, beasts and eggs field; Many scholars have carried out based on the birds, beasts and eggs order of magnitude model of image processing techniques and the research of quality model, have set up duck's egg, egg order of magnitude model like Wang Qiaohua, Xiong Lirong, put down in week and have set up egg volume and surface area computing method and the prediction of quality model based on machine vision; In egg fowl breed breeding field, mainly study the relation of birds, beasts and eggs essential characteristic parameter and egg fowl kind, the regression equation that draws with the egg (sample) of some like Ayupov, Narushin V. G. is calculated and is estimated volume [0.523
LB 2, 0.525
LB 2].And, do not see the pertinent literature report with the aspect of standard spheroid body volume estimation birds, beasts and eggs volume and quality.
Summary of the invention
The objective of the invention is provides a kind of volume and quality of estimating non-standard spheroid birds, beasts and eggs with standard spheroid body calculation method of physical volume in order to solve the deficiency of birds, beasts and eggs volume and Mass Calculation method.
Technical scheme of the present invention is: a kind of birds, beasts and eggs volume and Mass Calculation method based on the line of apsides, carry out according to following step: the maximum major axis footpath of measuring birds, beasts and eggs
LWith maximum short shaft diameter
B, with standard spheroid body volume calculation formula (π
LB 2/ 6) estimate the volume of these birds, beasts and eggs
VBy the estimation volume of gained estimation quality m (ρ again
V), wherein ρ is the density of birds, beasts and eggs, the density of general birds, beasts and eggs is 1.1g/cm
3
Wherein said birds, beasts and eggs are various eggs, duck's eggs such as fresh hen egg, foreign egg, fresh duck's egg.
Beneficial effect of the present invention:
1, directly estimate the volume of non-standard spheroid birds, beasts and eggs with standard spheroid body calculation method of physical volume, the measurement parameter that relates to is few, and computing method are simple.
2, standard spheroid body volume calculation formula and spheroid cubature formula are similar, are used to estimate that the birds, beasts and eggs volume ratio is more simple and clear, are convenient to memory.
3, help simplifying birds, beasts and eggs volume-based model and quality model, reduce calculated amount, can estimate turnout simultaneously based on computer image processing technology.
4, help the foundation of birds, beasts and eggs dynamic analysis and model in the hierarchical processing.
5, help the birds, beasts and eggs package design.
6, for one case to be provided with regular geometric volume description irregular geometry.
