PIPE THICKNESS MEASUREMENT DEVICE AND METHOD, AND RECORDING MEDIUM

摘要

A pipe thickness measuring device 10 is provided, including a luminance profile obtaining unit obtaining luminance profiles of radiographic images of a pipe to be measured in a direction crossing the pipe, an outer diameter point detecting unit detecting outer diameter points of the pipe based on the obtained luminance profiles, a region setting unit setting a predetermined region inside two of the outer diameter points of the pipe detected by the outer diameter point detecting unit, and an inner diameter point detecting unit detecting inner diameter points of the pipe based on a luminance profile corresponding to the set predetermined region from among the luminance profiles obtained by the luminance profile obtaining unit.
