Modelling and Correction of Influences on Surface Temperature Measurements using infrared thermography for animal health and welfare assessments

چکیده
For specific applications of infrared thermography (IRT) in the field of human medicine diagnosis, well defined standard operating procedures are used (e.g. controlled ambient conditions). In contrast, when IRT is used in the veterinary and animal science field, examinations are not always performed under controlled ambient conditions. This leads to unavoidable influences to the surface temperatures measured with IRT. This paper quantifies this effect and proposes a novel modelling and correction approach. This approach results in a significant increase in the quality of the data and provides a more accurate measurement of IRT for assessing animal health and welfare.

Recent Applications of Infrared Thermography for Animal Welfare and Veterinary Research: Everything from Chicks to Elephants
Eye temperature, measured using infrared thermography (IRT), is a non-invasive tool for evaluating the stress response in cattle, bison and elk to surgical procedures. Infrared thermography has recently revealed that a rapid drop in eye temperature is likely a sympathetically mediated response via vasoconstriction that can be used to detect fear and/or pain related responses in animals to diffe...

متن کاملRESOLUTION OF A THREE-DIMENSIONAL UNSTEADY INVERSE PROBLEM BY SEQUENTIAL METHOD USING PARAMETER REDUCTION AND INFRARED THERMOGRAPHY MEASUREMENTS Nortershauser and P. Millan
A three-dimensional unsteady inverse model has been developed in order to compute heat fluxes and surface temperature in various configurations. Temperature measurements are taken backside using infrared thermography. The number of unknown parameters is reduced using a discrete cosine transform analysis and by canceling values lower than a prescribed level. The efficiency of the method is prove...
