Document Type and Number:
Japanese Patent JP6973426
Kind Code:
B2
Abstract:
To provide a temperature measurement system, temperature measurement method, and method of manufacturing pipes, which allow for accurately measuring temperature of pipe-end inner surfaces.SOLUTION: Provided is a temperature measurement system for measuring temperature of pipe-end inner surfaces, or inner surfaces of end portions of a tubular object. The system comprises: image capturing means provided to be movable in an axial direction of the tubular object and configured to capture images of pipe ends including inner surfaces thereof; information acquisition means for acquiring size information of the tubular object; adjustment means for adjusting positions of both pieces of the image capturing means in the axial direction and/or an attitude angle thereof on the basis of the size information; and temperature computation means configured to derive temperature of the pipe-end inner surfaces from the images captured by the image capturing means.SELECTED DRAWING: Figure 1
