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

    【課題】設置が容易で装置を大型化することなく且つ直接トロリ線の偏摩耗・傾斜摩耗を測定することを可能としたトロリ線摩耗測定装置を提供する。【解決手段】トロリ線6の下面を撮影するカメラ2−1・・・2−nを検査車両1の屋根上に設置し、カメラで撮影されたトロリ線画像を画像処理して、トロリ線の残存直径を求める画像処理部5を備えたトロリ線摩耗測定装置において、複数のカメラを、それぞれ設置位置を把握された状態で枕木方向に沿って配置するとともに、画像処理部に、各カメラから入力されるトロリ線画像上にあるトロリ線の端点を入力する架線摩耗端点入力部と、画像上のトロリ線の端点からトロリ線の摩耗端点の三次元座標を算出する三角測量部と、トロリ線の摩耗端点の三次元座標からトロリ線の下面の傾斜角度を算出する偏摩耗・傾斜摩耗算出部とを設けた。【選択図】図1
