To provide an abrasion measuring apparatus and an abrasion measuring method which can calculate a remaining diameter corresponding value of a three-sided abrasion trolley wire.SOLUTION: An abrasion measuring method according to the present invention has steps of calculating a real coordinate P0 of a trolley wire center point from an image 11 by analyzing images I1 and I2 captured by first and second line sensor cameras 1, 12 provided on a roof of a vehicle 10, calculating height of a lowermost surface of a trolley wire 16 base on the information acquired by trolley wire lowermost surface position measuring means to calculate real coordinates P0 to P5 of boundary points p1 to p5 by using the image I1 and the height of the lowermost surface of the trolley wire 16, calculating an abrasion cross-sectional area S of the three-sided abrasion trolley wire 16 based on the real coordinates P0 to P5, and calculating, as the remaining diameter corresponding value H of the three-sided abrasion trolley wire 16, a remaining diameter of a horizontal abrasion trolley wire 16having a horizontal abrasion part 16a only whose cross-sectional area is the same as that of the three-sided abrasion trolley wire 16, based on the abrasion cross-sectional area S of the three-sided abrasion trolley wire 16.SELECTED DRAWING: Figure 7 【課題】三面摩耗トロリ線の残存直径相当値を求めることが可能な摩耗測定装置および摩耗測定方法を提供する。【解決手段】車両１０の屋根上に設置された第一，第二のラインセンサカメラ１１，１２によって撮影した画像Ｉ１，Ｉ２を解析して画像Ｉ１からトロリ線中心点の実座標Ｐ０を算出し、トロリ線最下面位置測定手段によって取得した情報に基づいてトロリ線１６の最下面の高さを求め、画像Ｉ１およびトロリ線１６の最下面の高さを用いて境界点ｐ１〜ｐ５の実座標Ｐ０〜Ｐ５を算出し、実座標Ｐ０〜Ｐ５に基づいて三面摩耗トロリ線１６の摩耗断面積Ｓを算出し、三面摩耗トロリ線１６の摩耗断面積Ｓに基づいて三面摩耗トロリ線１６と断面積が同一である水平摩耗部１６ａのみを有する水平摩耗トロリ線１６Aの残存直径を、三面摩耗トロリ線１６の残存直径相当値Ｈとして算出するようにした。【選択図】図７
