Abstract

An electric inspection car measures the wear area of the contact wire by laser to calculate the residual diameter of the contact wire. The contact wire in a Shinkansen tunnel rarely has any gloss along the wear surface. In that case, the measured wear area has some error. The authors considered the wear condition difference between the contact wire with gloss and that without gloss by measuring the two-dimensional cross-sectional shapes and the image of the wear surface.
