The present invention relates to a method for converting a thermal image and, more specifically, to a method for performing the conversion of an image in real time in non-cooling thermal equipment. The method for converting an image according to an embodiment of the present invention comprises: a uniform surface original data acquisition process for photographing a uniform surface having a uniform temperature to acquire uniform surface original data; a biasing adjustment process for calculating a offset value which is a difference between a characteristic value of the uniform surface original data and a predetermined reference value to adjust the voltage of a driving driver of the non-cooling thermal equipment in order to make the characteristic value equal to the reference value; a uniform surface correction data acquisition process for acquiring the uniform surface correction data of the time when the characteristic value of the uniform surface original data becomes equal to the predetermined reference value; a signal gain value calculation process for using a maximum value and a minimum value of the uniform surface correction data to calculate a signal gain value; a thermal image original data acquisition process for photographing a subject to acquire thermal image original data by frame; and a non-uniform correction process for using non-uniform correction which applies the signal gain value and the offset value to each pixel value of the thermal image original data to perform the conversion of the image to acquire thermal image correction data. |
