发明名称 INFRARED TEMPERATURE MEASURING DEVICE
摘要 PROBLEM TO BE SOLVED: To provide an infrared temperature measuring device capable of locally correcting a temperature measurement error due to a reflection component resulting from a surface shape of a measuring object. SOLUTION: The infrared temperature measuring device 10 including a temperature distribution calculation part 30 for calculating temperature distribution of the measuring object D from infrared energy and visible light, includes: an image creation part for creating a visible light image from visible light; a reference luminance value calculation part for calculating frequency distribution of luminance values of the individual pixels of the visible light image, and calculating as a reference luminance value a luminance value where the frequency distribution has a frequency peak; an image extraction part for extracting pixels of the visible light image whose luminance values are larger than the reference luminance value; a luminance ratio calculation part for calculating as a luminance ratio the ratio of the reference luminance value to the luminance value of the extracted pixel; a mask creation part for assigning the luminance ratio to the extracted pixel and assigning 1 to the other pixels as a luminance ratio, and creating a mask; and a temperature correction part for multiplying the temperature of each pixel of the infrared light image by the luminance ratio by using the mask to correct the temperature of each pixel of the infrared image.
