Abstract
A non-contact temperature scanning system capable of high-speed determination of core body temperature TC by estimating a representative skin temperature TS of a subject from a thermal image. The system employs a biophysical model which considers heat transfer properties. In particular, the model takes into consideration of the ambient temperature TA and relative humidity Rh in addition to estimating TS from a thermal image. Once TS is determined, TC can be calculated based on the biophysical model which takes into consideration TA and Rh.
Claims14
A temperature scanning system comprising:
- a thermal image capture module configured to capture thermal images;
- an ambient sensor module configured to capture ambient conditions;
- and
- a processing module configured to process a thermal image
- to estimate a skin temperature (TS) of a subject in the thermal image, and
- to calculate a core temperature (TC) of the subject based on the estimated skin temperature and current ambient conditions.
A method for non-contact temperature scanning comprising:
- capturing a thermal image of a subject with current ambient conditions;
- processing the thermal image to detect a hot spot of the subject;
- determining a skin temperature TS of the subject from the hot spot;
- and
- calculating a core temperature TC of the subject from the TS taking account of the current ambient conditions.
