Abstract
A phase calculation unit () calculates, as a first phase, a deflection angle of a first similarity vector having a first similarity and a second similarity calculated by a similarity calculation unit () as elements. The phase calculation unit () calculates, as a second phase, a deflection angle of a second similarity vector having a third similarity and a fourth similarity calculated by the similarity calculation unit () as elements. A period calculation unit () calculates a period of a pattern formed on a long body on the basis of the first phase and the second phase calculated by the phase calculation unit (). An abnormality detection unit () detects an abnormality in the long body on the basis of the period calculated by the period calculation unit ().
