During thermovision measurement in an open atmospheric space, the surroundings consists of two elements: the ground surface and apparent surface of the sky. To determine the equivalent ambient temperature it is necessary to know the temperature of the sky [3, 4]. It has been proposed to measure the temperature distribution of the sky using an infrared camera. However, such a measurement has a problem because often the temperature of the sky is too low to measure its value with an IR camera. The article presents a method for measuring the low temperature of the sky with a value outside the measuring range of the IR camera. The method consists in making a measurement with artificial values of measurement parameters that ensure obtaining the temperature value belonging to the measuring range of the camera. Then, using the developed algorithm, the obtained temperature value is converted to the actual conditions.
