PROBLEM TO BE SOLVED: To provide a wear measuring instrument capable of measuring the wear amount of a trolley wire with an irregularly shaped groove with high accuracy and a method thereof.SOLUTION: In a trolley wire wear measuring instrument by image processing provided with an image processor in which a line sensor camera for photographing the underside of a trolley wire is installed on the roof of a vehicle, and an image of the underside of the trolley wire photographed by the line sensor camera is subjected to image processing to measure the wear width of the trolley wire, the image processor includes an inclination correction processing part 14g of a trolley wire wear width for acquiring the real wear width of the trolley wire obtained by correcting a wear width in accordance with an inclination angle of the underside of the trolley wire that inclines following the upper surface shape of a pantagraph, and an inclination correction processing part 14h of a trolley wire residual diameter for acquiring the residual diameter of the trolley wire on the basis of the real wear width of the trolley wire acquired by the inclination correction processing part 14g of a trolley wire wear width and the inclination angle of a trolley wire wear surface to a sleeper direction.

    【課題】異形みぞ付トロリ線の摩耗量を高精度に測定可能な摩耗測定装置及びその方法を提供する。【解決手段】トロリ線の下面を撮影するラインセンサカメラを車両の屋根上に設置し、ラインセンサカメラで撮影されたトロリ線の下面の画像を画像処理してトロリ線の摩耗幅を測定する画像処理装置を備えた画像処理によるトロリ線摩耗測定装置において、画像処理装置に、パンタグラフの上面形状に倣って傾斜するトロリ線の下面の傾斜角度に応じて摩耗幅を補正しトロリ線の真の摩耗幅を求めるトロリ線摩耗幅の傾斜補正処理部14gと、トロリ線摩耗幅の傾斜補正処理部14gにより求めたトロリ線の真の摩耗幅及びトロリ線摩耗面の枕木方向に対する傾斜角度に基づいてトロリ線の残存直径を求めるトロリ線残存直径の傾斜補正処理部14hとを設けた。【選択図】図3
