A method for estimating human body temperature includes receiving, via a thermal camera, a thermal image captured of a real-world environment, the thermal image including thermal intensity values for each of a plurality of pixels of the thermal image. A position of a first human face is identified within the thermal image, the first human face corresponding to a first human subject. A skin tone of the first human face is identified. Based on the identified skin tone, a skin tone correction factor is applied to one or more thermal intensity values of one or more pixels corresponding to the first human face to give one or more tone-corrected thermal intensity values. Based on the one or more tone-corrected thermal intensity values an indication of a body temperature of the first human subject is reported.
