Abstract
While a reference means having a positional relationship to the pass-line of a continuance mill determined in advance and caliber profile (area enclosed by the groove profile of a rolling roll) formed by a rolling roll at each stand are imaged within the same visual field and a position corresponding to the pass-line is calculated based on the region corresponding to the reference means within the taken image, the center position of the region corresponding to the caliber profile within the taken image is calculated and the misalignment amount of the caliber profile can be calculated based on the calculated center position and the calculated position corresponding to the pass-line. Accordingly, a misalignment amount can be measured accurately as long as images of the reference means and the caliber profile are taken within the same visual field.
