Title:
TEMPERATURE MEASUREMENT DEVICE AND TEMPERATURE MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/029231
Kind Code:
A1
Abstract:
A temperature measurement device for measuring the temperature of a steel sheet, wherein: an imaging unit, which is a spectral camera, has a field of view that includes at least a portion of the steel sheet in the width direction of the steel sheet, and acquires the radiance of the steel sheet at a plurality of wavelengths at positions on a surface of the steel sheet in the field of view; and a calculation processing unit 14 selects two wavelengths from among the wavelengths at which the radiance of the steel sheet is acquired by the imaging unit, and uses the radiance of the steel sheet, which has been acquired by the imaging unit at the selected two wavelengths, to calculate the temperature at each of the positions on the surface of the steel sheet by two-color radiation pyrometry.
