Method for determining heat and reflected heat in thermal image

A method of determining heat and reflected heat in a thermal image, the method comprising:

• a) photographing a subject through a thermal imaging camera, and collecting a thermal image of the subject;
• b) analyzing features based on a thermal image temperature distribution of the thermal image;
• c) detecting heat and reflected heat in the thermal image based on the analysis in step b);
• and
• d) displaying the heat and the reflected heat in the thermal image, detected in step c), as heat and reflected-heat regions in the thermal image,
• wherein the step b) comprises:
• (i) extracting a region-of-interest of the thermal image through machine learning based on an object extraction neural network;
• (ii) extracting raw data for each pixel of the region-of-interest;
• and
• iii) extracting temperature data of the region-of-interest, and separately managing or filing the extracted temperature data,
• wherein the step c) comprises analyzing variance in temperature between a pixel to be analyzed in the region-of-interest and surrounding pixels to determine reflected-heat spots corresponding to the pixels between which the variance in temperature is greater than or equal to a preset threshold.
