Abstract :
In order to evaluate IR images obtained under various thermal environmental conditions, we proposed a human thermal model that can be used for converting IR images into those under a standard condition. The developed model was based on a numerical calculation of bio-heat transfer equations that express heat transfer phenomena within the human body and a mathematical model of the thermoregulation system. A comparison of an IR image which was converted under the standard condition (30°C) with the original one at 30°C indicated that the method using our model was effective to eliminate the influence of the thermal environmental condition.
