2.4 - Precise IR-Based Temperature Measuring- a Case Study for the Automatic Health Monitoring of Dairy Cows

W. Wirthgen, St. Zisper, S. Geidel & U. Franze
The modern livestock farming requires novel systems for an automatic health monitoring of animals like dairy cows. Infrared thermography (IRT) has been suggested for veterinary diagnostic, but due to the lack of a reliable precise temperature measurement under operating farming conditions and personal expense analysis the veterinary IRT diagnostic is rarely used in practice. Starting from the requirements of a maximal temperature measurement uncertainty of ± 0.3 K (DIN12470-5, medical infrared thermometers) the IRT measurement...
