Document Type and Number:

WIPO Patent Application WO/2016/157289

Kind Code:

A1

Abstract:

This detector is provided with a sensor head (2), a data processing unit (8), a similarity degree calculation unit (9), and an abnormality detection unit (10). The sensor head (2) acquires surface data about an elongate body. The data processing unit (8) generates first processing data from surface data acquired by the sensor head (2) at a first site on the elongate body. The data processing unit (8) generates second processing data from surface data acquired by the sensor head (2) at a second site on the elongate body. The similarity degree calculation unit (9) calculates a degree of similarity between the first processing data and the second processing data. The abnormality detection unit (10) detects abnormalities in the elongate body on the basis of the similarity degree.
