Abstract

The invention discloses an on-line detection method for hatching activity of hatching eggs based on least square method ellipse fitting, and relates to hatching egg detection technology. The method is as follows: ①Building an online detection platform for hatching activity of eggs; ②Collecting images of group hatching eggs; ③Segmenting images of group eggs by least squares ellipse fitting; ④Extracting image features; ; ⑥ test model. This method adopts the group egg image segmentation of the least square method ellipse fitting, and accurately separates a single breeding egg from the group egg image; by analyzing the color features and texture features of the image, 12 and 13 eggs are screened out respectively as Distinguishing the image features of non-sperm eggs and dead embryo eggs reduces the complexity of model calculations; using machine vision technology, it realizes the online non-destructive detection of the hatching activity of group breeding eggs, reduces the damage to breeding eggs, and improves the efficiency of egg enterprises for hatching. egg detection efficiency.

Description

technical field [0001] The invention relates to hatching egg detection technology, in particular to an on-line detection method for egg hatching activity based on least square method ellipse fitting. Background technique [0002] The egg hatching process takes about 21 days, which has high requirements on the environment and is a time-consuming and energy-consuming process. According to statistics, the success rate of breeding eggs is between 85% and 95%. Early detection of fertilized eggs and dead embryonated eggs in this process can effectively save incubation space and energy, reduce economic losses, and ensure that other normal eggs continue to hatch [Zou Xiurong, Pan Leiqing, Tu Kang, etc., non-destructive testing of hatching quality of chicken breeder eggs Research progress of [J]. Food Industry Science and Technology, 2010,31(2):342-347.]. [0003] At present, many scholars have realized the non-destructive detection of the viability of breeding eggs. Pan Jinming e...
