Abstract
The purpose of this study is to investigate the effects of external factors – including environmental conditions (e.g., ambient temperature, ambient relative humidity), and deployment parameters (e.g., working distance, viewing angle, setting temperature of external temperature reference source (ETRS)) – on the use of infrared thermographs (IRTs) for elevated body temperature (EBT) detection. These effects were theoretically evaluated through computer simulation and experimentally evaluated through bench tests. Overall, the insights into the influence of these factors provided by this study may improve IRT performance and thus enhance the potential of IRTs as countermeasures for high-quality point-of-care EBT screening.
