Abstract:
A method, system, and non-transitory computer readable medium storing a plurality of computer executable instructions for calibrating an uncalibrated thermal imager is provided. The system includes a calibrated pyrometer for determining a first temperature of a Region of Interest under a first condition, and an uncalibrated thermal imager for determining a first average count value over the region of interest under the first condition and for determining a second average count value over the region of interest under a second condition. A temperature sensor for determining a second temperature of the region of interest under a second condition is also provided. Control electronics determine a Planck function that intersects the points (first temperature, first average count value) and (second temperature, second average count value). The uncalibrated thermal imager is calibrated using the Planck function.
