PROBLEM TO BE SOLVED: To provide a trolley wire wear measurement device that is easy to be installed and that makes it possible to measure the uneven wear and inclined wear of a trolley wire directly without increasing the device in size.SOLUTION: Provided is a trolley wire wear measurement device having cameras 2-1 to 2-n for photographing the underside of a trolley wire 6 installed on the roof of an inspection vehicle 1 and equipped with an image processing unit 5 for processing the trolley wire images photographed by the cameras and finding the remaining diameter of the trolley wire, wherein the plurality of cameras are arranged along the direction of sleepers while their respective positions are grasped, and the image processing unit is provided with an aerial wire wear end point input part for inputting the end point of the trolley wire in the trolley wire images which is inputted from each camera, a trigonometrical survey part for calculating the three-dimensional coordinates of the wear end point of the trolley wire from trolley wire end points in the images, and an uneven wear/inclined wear calculation part for calculating the angle of inclination of the underside of the trolley wire from the three-dimensional coordinates of the wear end point of the trolley wire.SELECTED DRAWING: Figure 1 |
