Relationship between Infrared Thermal Imaging Temperature and Rectal Temperature of Tan Sheep
In order to improve the monitoring and early warning ability of health,estrus,stress and epidemic diseases of Tan sheep in sheep farms,and to achieve rapid,non-contact and stress-free acquisition of Tan sheep body temperature,50 six-month-old Tan ewes were collected,and the rectal temperature and characteristic Infrared thermography(IRT)temperature data of eyes,ears and nose were collected to study the measurement method of using local IRT temperature instead of body temperature(rectal temperature).Through statistical analysis,it was found that the rectal temperature and eye IRT temperature have small dispersion and strong stability.The eye IRT temperature is most affected by the rectal temperature,which is significantly positively correlated with the rectal temperature,and is also the closest to the rectal temperature and easy to measure.Therefore,the eye is used as the temperature measurement site for Tan sheep infrared thermal imaging,and then the linear model and polynomial mathematical model are used to construct the relationship model between Tan sheep IRT temperature and rectal temperature,and the test group data fitting comparison found that the average absolute error of the linear model is 0.215℃,The average relative error is 0.548%,and the fitting degree is the best and the accuracy is the highest,which can be used to detect the body temperature of Tan sheep.
