Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The pig breathing frequency detection method of the present invention is implemented based on on-site video image acquisition and monitoring equipment. On-site video image acquisition and monitoring equipment is composed of camera equipment, video acquisition card, lighting and computer, as well as corresponding image acquisition, transmission and storage algorithms and software. The on-site video image acquisition and monitoring equipment is used for the acquisition, transmission and storage of video images in the computer, and then the software system performs corresponding algorithm processing and identification, and the computer outputs the respiratory rate of the target pig.

Abstract

The invention discloses a pig respirator rate detecting method and a device on the basis of machine vision. The pig respirator rate detecting method includes acquiring movement track of pigs by acquiring movement conditions of pigs on site through a video camera, measuring movement rules of overlooked ventral curves of the pigs and computing respiratory rate of the pigs, and is capable of realizing contactless respiratory rate detection and substituting for the conventional visual observation, so that human input is reduced and accuracy is increased. The pig respirator rate detecting device comprises video acquisition equipment, a transmission module, a processing module and a display and storage module, and is simple in installation, high in detection precision and environmental adaptability.

Description

technical field [0001] The invention relates to machine vision technology and pig behavior detection and recognition technology, in particular to a precise measurement method and device for pig breathing frequency based on machine vision. Background technique [0002] The pig farming industry has changed from a traditional extensive farming model to a green and intensive farming model. The traditional method of observing the breathing rate of pigs is achieved by visually observing the ups and downs of the pig's chest and abdomen. Due to the poor environment in the pig house , Observing in the pig house for a long time will affect the health of the staff, and only relying on manual observation, factors such as human fatigue and cognitive level will lead to omission of information, so this method is time-consuming, laborious and inaccurate. Therefore, Finding a more reliable, more accurate and more convenient method for detecting the respiratory rate of pigs has become an urge...
