레일 마모도 계산을 위한 프로파일 매칭 방법

In this paper, we describe a method for precisely measuring the abrasion of the railway using an image processing technique. To calculate the wear of the rails, we provided a method for accurately matching the standard UIC60 type rail profile data and the profile data acquired by the rail inspection vehicle. We try to Shape Matching using poles for profile matching and performed additional adjustment using the slope of the straight section of the profile in order to improve the accuracy. As a result of attempts to matching in such a way as described above, our method showed the excellent performance of matching accuracy within 0.1mm.
