AI Technical Summary
Existing non-contact radiation thermometry methods are prone to inaccurate body temperature measurements due to factors such as changes in ambient temperature, thermal imager temperature drift, and skin reflection from the subject.
Using a radiation reference source with the same radiation characteristics as human skin, combined with a constant temperature heater and a data acquisition module, body temperature is determined through a preset algorithm. The reference temperature and radiation parameters of the radiation reference source are used to eliminate the influence of environmental factors.
It improves the accuracy of body temperature measurement by using a relative measurement method to offset the influence of environmental factors and the emission ratio of the measured object on the temperature measurement results, thus achieving high-precision body temperature measurement.
