Embodiment Construction

[0050] The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0051] figure 1 It is a flowchart of an embodiment of the method for detecting the size and egg shape index of poultry eggs of the present invention. As shown in the figure, the detecting method of this embodiment includes the following steps S11 to S14.

[0052] S11. Collect images of poultry eggs, and filter the collected images.

[0053] Select a certain number of test samples of poultry eggs and mark them separately. At the same time, use a vernier caliper to actually detect its longitudinal diameter and maximum transverse diameter, and record the detection data.

[0054] Collect egg images (e.g. figure 2 As shown), the RGB color space of the image is obtained after filtering.

[0055] S12. In the RGB color space of the filtered image, the R component is used as a variable function, and the edge points of the eggs in the image are detected by th...

Abstract

The present invention relates to a method of detecting the size of poultry eggs and egg shape index. The method comprise steps of collecting the image of an poultry egg, filtering the collected image; detecting the marginal points of the poultry egg in the image by using R component as a variable function and utilizing the dichotomy in the RGB color space of the filtered image; calculating the centroid of the poultry egg by utilizing the obtained marginal points information; using the centroid as the basic point to search the longitudinal diameter and the maximum transverse diameter of the poultry egg. The technical scheme of the present invention has the characteristics that (1) the image does not need binarization; (2) marginal detecting adopts dichotomy and the detecting speed is high; (3) a simplified centroid calculating method is adopted and the efficiency is high; (4) the detecting accuracy is high.

Description

Technical field [0001] The invention relates to a non-destructive detection technology for agricultural products, in particular to a detection method for the size and egg shape index of poultry eggs. Background technique [0002] The detection of egg size and egg shape index has important applications in the egg industry. During transportation, poultry eggs are required to be packaged according to size to reduce damage; during sales, they are required to maintain appearance consistency to increase product prices. In addition, the egg shape index must be within a certain range during incubation to ensure the hatching rate. [0003] The Chinese invention patent "Method for Simultaneous Detection of Poultry Egg Size, Egg Shape Index and Weight" (CN1934935) discloses a detection method for simultaneous detection of poultry egg size, egg shape index and weight. This patent uses computer vision technology to collect egg images, perform binary segmentation, filtering and edge detection ...
