Abstract: Temperature detection systems and methods for detecting temperature of an object are provided. The system utilizes either a predetermined temperature reference by using a well-behaved and calibrated thermal camera with reliable internal temperature reference calibration or one or more calibrated temperature reference devices, such as a blackbody reference, in view of the camera. The system then determines temperature values for each pixel within the image based on mean and median reference temperatures determined from the predetermined temperature reference or the calibrated temperature reference devices and identifies any pixels in the image having a predetermined characteristics, such as those pixels having a temperature greater than the predetermined reference temperature or some other threshold, or, alternatively, pixels in a range of temperatures.

Abstract: A temperature detection system and method for detecting a correlation between temperatures on a subject and a temperature reference is provided. One or more calibrated temperature reference devices, such as a Body Temperature Reference blackbody system is used with an emissive source detector, such as a Mid Wave Infrared (MWIR) or Long Wave Infrared (LWIR) thermal camera that is capable of imaging both a subject and the calibrated temperature reference devices. A processor maps each pixel within the image to a specific thermal value based on the mean and median reference temperatures from the calibrated temperature reference devices and identifies any pixel in the image having a temperature greater than the reference temperature. This information can be used to detect an elevated temperature from a subject. The system and method can be used to detect fevers, tumors, infections, parasites, and the like.
