Abstract

The invention discloses a system and method for automatically tracking the rumination behavior of cows based on video. The system includes a video input module, an LK optical flow processing module, a mathematical morphology processing module, and a KCF tracking and display module; the video input module acquires The first six frames, resolution and frame rate of the input video; the LK optical flow method processing module obtains the corresponding optical flow field according to the first six frames of the video, binarizes it after it is merged; the mathematical morphology processing module binarizes The final image is corroded, opened, screened, opened again, and screened again, and then the position coordinates of the cow’s mouth are calculated according to the connected domain; the KCF tracking and display module compares the cow’s mouth in the video according to the obtained position coordinates. The part is tracked and the tracking result of each frame is displayed. The invention also discloses a video-based method for automatically tracking the rumination behavior of dairy cows.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry and relates to a system and method for automatically tracking the rumination behavior of dairy cows based on video. Background technique [0002] Dairy cows can ruminate for up to 8 hours a day, and the chewing time for each rumination is 50-60 seconds. The number of ruminations per day varies from 200 to 450 times. It depends on the amount and length of crude fiber in the diet. Observe the cows At least one-third of the cattle must be ruminating at the same time to indicate that the amount of crude fiber in the diet is sufficient, otherwise attention should be paid. A cud is chewed about 40 to 60 times. In the process of dairy cow breeding, it is very important to track the rumination behavior of dairy cows. If it is done manually, it will be time-consuming and laborious, and there will be certain errors. Contents of the invention [0003] The purpose of the present invention is to p...
