Embodiment

[0042] like Figure 1-Figure 4 Shown, a kind of pig behavior rhythm analysis method, comprises the steps:

[0043] S1 Install a monitoring camera at the pig production site. The pig production site is within the field of view of the camera, and the pigs are marked to distinguish the pigs;

[0044] S2 as figure 2 As shown, the real-time monitoring video of the pig production site is obtained. The module first divides the image to obtain a binary image, and then fits the pig ellipse to locate the individual pig and determine the moving distance of the pig;

[0045] Specifically:

[0046] Using the reference object method, specifically, placing a calibration plate on the pig production site to obtain the mapping relationship between the image pixel distance and the actual distance, and then applying the method based on the combination of color features and morphological features to segment the pigs with mild adhesion and adopt The least squares method is used to fit the ellip...

Abstract

The invention discloses a pig behavior rhythm analysis method, which comprises the steps of S1, installing a monitoring camera at the pig production field, and marking pigs so as to differentiate the pigs; S2, acquiring monitoring video of the pig production field in real time, positioning individual pigs, and determining the movement distance of the pigs; S3, judging pig behaviors according to the movement distance of the pigs in unit time; S4, and building a pig behavior rhythm model by combining behavior data of pig individual growth cycle and behavior data between groups. The pig behavior rhythm analysis method is simple in structure, convenient, easy to use, and suitable for being deployed and applied in a large scale to the breeding industry.

Description

technical field [0001] The invention relates to the field of distributed remote communication, in particular to a method for analyzing pig behavior rhythm. Background technique [0002] The behavioral rhythm of pig growth cycle under natural conditions is an important basis for pig growth monitoring, production performance analysis, disease early warning, etc. In the past, due to limited conditions, it was difficult to analyze the behavior of pigs. With the rapid application and development of high-definition video network monitoring technology and image processing and analysis technology, it is possible to use machine vision instead of human eyes to analyze pig behavior; [0003] Many scholars at home and abroad have carried out relevant research on pig behavior. In the prior art, the individual pigs are located by marking the pigs’ backs, and the method of monitoring the drinking behavior of the pigs and quantifying the movement of the pigs is further used; or the face-t...
