Example Embodiment

A certain number of test samples of eggs were selected and labeled separately. The longitudinal diameter and the maximum transverse diameter were actually detected by vernier calipers, and the weight was actually weighed by an electronic balance, and the test data was recorded.

Figure 3 is a schematic view of a process of rotating a poultry egg boundary;

Figure 5 is a schematic view showing the position of a poultry egg boundary after rotation and translation;

At a certain angular interval, each point on the border of the egg is rotated in the range of 0° to 180°, and each time it is completed, it is called a round, and a total of K rounds are required. For example, when the angular interval is 1°, the K value is 180. The pixel point P0(x0, y0) on the border of the egg is rotated by an angle β, and its new coordinate position P(x, y) is calculated by the formula (1) (as shown in Fig. 3):

{

After the end of each round of rotation, record the Ti (i = 1, 2, ..., K) point with the largest Y ...

Abstract

The present invention discloses a method for simultaneously detecting egg size, egg form index and egg weight. It is characterized by that said invention adopts an egg image analysis and processing method to attain the goal of simultaneously detecting egg size, egg form index and egg weight. Said invention also provides the concrete steps for implementing said method and also provides the concrete requirements for implementing every step.

Description

technical field [0001] The invention relates to a method for simultaneously detecting poultry egg size, egg shape index and weight. Background technique [0002] my country is a big country in the poultry industry in the world, and the poultry industry is one of the pillar industries of my country's agriculture. In 2005, my country's annual output of poultry eggs reached 24.348 million tons, accounting for 41.1% of the world's total output. However, the technical means of poultry egg detection and grading in my country is backward, the automation degree of detection and grading equipment is low, and the proportion of poultry eggs that have been commercialized (including simple manual grading) is quite low. The outer packaging of the product is generally poor, it is difficult to meet foreign poultry egg testing and grading standards, and it lacks international market competitiveness. This is something that our country urgently needs to improve and make up for. [0003] The s...
