Abstract
A meandering amount arithmetically operating device of a meandering amount measurement device calculates the meandering amount of a steel sheet using a drive side edge site z(N) and a work side edge sites z(N) at a current time when a measurement reliability determination unit determines that both the drive side edge site z(N) and the work side edge sites z(N) at the current time have high reliability. When only one of the drive side edge site z(N) and the work side edge site z(N) at the current time is determined to have high reliability, the other edge site is calculated by interpolation using the number of pixels W from a sheet width updating unit with the drive side edge sites z(N) or the work side edge site z(N) at the current time having high reliability as a reference.
