Abstract
The radiance coming from the interior of an uncooled infrared camera has significant effect on the accuracy of temperature measurement. To remove the effect, this paper proposes a novel three-phase method, which is outlined below. First, from a set of samples, how the pixel value of each blackbody varies with the camera temperature is determined. Second, at the given camera temperature, the calibration function, describing how the pixel value varies with the temperature of blackbody is formed. Finally, with the aid of the calibration function, the temperature of the probe object can be determined by its pixel value. Experimental results show that with the method, the camera can measure the temperature of the object with an error of no more than 1°C.
