Flexible contact network abrasion measurement method based on template secondary lamination

A flexible overhead contact system abrasion measuring method based on template secondary fitting comprises the steps that fitting is conducted on an actual overhead contact system wire scanning contour through a wire template contour, the position and posture of the wire contour in the non-abrasion state are confirmed, the difference between the fitted wire contour and the actual wire contour is the actual wire abrasion interface, and then the actual wire abrasion interface is obtained. Therefore, the abrasion calculation of the flexible overhead line system wire is realized. According to the method, the lead surface is not required to be a standard circular arc and the two sides of the lead surface are part of a lead diameter circle any more, fitting calculation is performed depending on an actual lead template, the algorithm robustness is good, the problem that the detection precision is lower when the chord length calculation method is closer to the circle center is solved, the practicability is high, and
