Problems solved by technology

[0003] (1) The predictive model of the dependent variable and the independent variable is usually nonlinear, and the relationship between them cannot be explained geometrically;
[0004] (2) During the detection, the longitudinal diameter and the maximum transverse diameter are mainly detected manually, and then the parameters are substituted into the regression equation, which is slow and inefficient

Embodiment Construction

[0043] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0044] figure 1 It is the flow chart of the embodiment of the detection method of poultry egg volume and surface area of ​​the present invention, as shown in the figure, the detection method of the present embodiment comprises the following steps:

[0045] S1. According to the acquired RGB color image of poultry eggs, extract geometric coordinate information of edge pixels of poultry eggs in the RGB color image.

[0046] Select a certain number of test samples of poultry eggs and mark them separately. Measure the true volume of poultry eggs (V, unit: cm 3 ); break the poultry egg, take out the contents, measure the total volume of the eggshell by the drainage method, and measure the thickness of the eggshell by using a screw micrometer, and calculate the approximate True surface area (S, unit: cm 2 ), and record the test data.

Abstract

The invention relates to a method for detecting the volume and surface area of poultry eggs. The method includes the following steps of: S1. extracting the geometric coordinate information of an edge pixel point of poultry eggs in a RGB color image according to the obtained poultry egg RGB color image; S2. calculating the pixel volume and V(p) of poultry eggs, as well the pixel surface area and S(p) according to the extracted geometric coordinate information of the edge pixel point; S3. establishing a relation model of actual volume V and pixel volume and V(p), and of actual surface area S and pixel surface area and S(p) according to the pixel volume, V(p), pixel surface area and S(p); and S4. detecting the actual volume V and the actual surface area S of the poultry eggs according to the relation models. The technical proposal of the invention has the following advantages of: (1) fast detection speed and high accuracy with the use of a machine vision method; and (2) no-wear property and no influence on the quality of the poultry eggs in the detection process.

Description

technical field [0001] The invention relates to a non-destructive detection technology for agricultural products, in particular to a detection method for poultry egg volume and surface area. Background technique [0002] Egg volume and surface area and other characteristic parameters are of great significance in the egg processing industry and biological research. They have been widely used in the study of the number distribution and ecological morphology of laying hens of different ages, and can predict the birth weight and hatching rate of laying hens. , eggshell surface characteristics and egg internal quality parameters, etc. In addition, during transportation, poultry eggs are required to be graded and packaged according to volume to reduce damage; during sales, it is required to maintain consistency in appearance to increase product prices. The drainage method can be used to accurately measure the volume of poultry eggs, but the target needs to be air-dried after the ...
