Temperature control system, temperature control method and temperature control program for facility equipment

A method for controlling the surface temperature of facility equipment using a non-fixed image-capturing device for capturing a visible image and a thermal image by capturing the image of the surface of the facility equipment and a display device for displaying the visible image and the thermal image the method comprising:

• an imaging step of capturing, by the non-fixed image capturing device, at a specific measurement point in the facility where a marker is present, a first visible image and a first thermal image corresponding to the first visible image, and capturing, at a different time, the same measurement point in the facility by the non-fixed image capturing device to obtain a second visible image and a second thermal image corresponding to the second visible image;
• a comparison-area setting step for setting a comparison area, the comparison area at the same position and in the same range of the first visible image and the first thermal image and the second visible image and a second thermal image based on the shape information of the marker as a common reference part present, the comparison area between the first visible and thermal images obtained by the capturing of the image of the specific measurement point of the facility equipment and the second visible and thermal images obtained by the capturing of the image of the same measurement point of the facility equipment at the different time;
• a correction step for correcting a deviation of a field angle in the comparison area of the first and second thermal images so that a first thermal image corresponding to the first visible image and a second thermal image corresponding to the second visible image are superimposed;
• a temperature-difference information obtaining step for obtaining temperature difference information by comparing the corrected thermal images;
• and
• a temperature difference information display step for displaying the temperature difference information on the display device, and
• a frame reflecting step for superimposing and reflecting a first frame defining an outline of the comparison area set in the first visible image onto the first thermal image corresponding to the first visible image and superimposing and reflecting a second frame defining an outline of the comparison area set in the second visible image onto the second thermal image corresponding to the second visible image, and wherein the correction step corrects the deviation of the field angle concerning the comparison area of the first thermal image corresponding to the first visible image and the second thermal image corresponding to the second visible image enabling superimposition of the first thermal image and the second thermal image.
