  Since late 2019, the global spread of COVID-19 has affected people's daily
life. Temperature is an early and common symptom of Covid. Therefore, a
convenient and remote temperature detection method is needed. In this paper, a
non-contact method for detecting body temperature is proposed. Our developed
algorithm based on blackbody radiation calculates the body temperature of a
user-selected area from an obtained image. The findings were confirmed using a
FLIR Thermal Camera with an accuracy of 97%.
