MEASUREMENT OBJECT SURFACE ABNORMALITY IDENTIFICATION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a measurement object surface abnormality identification device capable of accurately identifying a surface abnormality such as oxidized scale generated on a high-temperature measurement object.

SOLUTION: The present invention uses a measurement object surface abnormality identification device 1 which comprises: an image synthesis section 10 which creates a synthesized radiant light image by synthesizing a plurality of radiant light images obtained through imaging radiant light from a high-temperature measurement object 5 by a radiant light imaging section 18 every time the measurement body rotates a prescribed angle; a first luminance correction section 12 which extracts a prescribed region from the synthesized radiant light image and corrects a luminance change in an image of the prescribed region due to a reduction in temperature of the measurement object 5 during the same is imaged; and an abnormality determination section 14 which detects a prescribed dark section in the prescribed region of the corrected image and determines that the dark section in the prescribed region of the image is a surface abnormality of the measurement object.
