Embodiment Construction

[0036] Select a certain number of test samples of poultry eggs and mark them separately. Use a vernier caliper to actually detect its longitudinal diameter and maximum transverse diameter, use an electronic balance to actually weigh its weight, and record the detection data.

[0037] Collect the image of poultry eggs (as shown in Figure 1), carry out binary segmentation, filtering and edge detection (as shown in Figure 2) to poultry egg image, obtain the boundary and centroid O of poultry eggs; Place the origin of coordinate system At the centroid O, take the horizontal direction as the X-axis direction, and the vertical direction as the Y-axis direction, and establish a plane Cartesian coordinate system (as shown in Figure 3).

[0038] (1) Find the end points T and B of the small end and the large end of the poultry egg (as shown in Figure 5).

[0039] According to a certain angle interval, rotate each point on the boundary of the poultry egg within the range of 0° to 180°, ...

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...
