Zusammenfassung:PROBLEM TO BE SOLVED: To provide a measurement system that can simultaneously measure thicknesses of both the sides of respective sliders disposed in a plurality of rows without using a plurality of imaging means and illumination means and prevents a decrease in measurement precision because of weather.SOLUTION: A measurement system includes: an imaging part 101 for acquiring a plurality of captured images having a parallax by photographing sliders 402, 403 of a pantograph 201 installed on a vehicle 202 running on a line 203; an illumination part 102 for lighting the sliders 402, 403; and an image processing part 104 for measuring the amount of wear of the sliders 402, 403 from the captured images. The sliders 402, 403 are disposed in a plurality of rows side by side in a line direction 207, the imaging part 101 and the illumination part 102 are installed at the same side relative to the line 203 at a side of the line 203, the illumination part 102 lights the sliders 402, 403 from above, and the imaging part 101 photographs the sliders 402, 403 within a photographing area 205 set between the imaging part 101 and the illumination part 102 from above.SELECTED DRAWING: Figure 3 【課題】複数の撮像手段および照明手段を用いることなく複数列に配置された各すり板の両側の厚みを同時に計測でき、かつ、天候によって計測精度が低下しない計測システムを提供する。【解決手段】線路203上を走行する車両202に設置されたパンタグラフ201のすり板402,403を撮影して視差を有する複数の撮像画像を取得する撮像部101と、すり板402,403を照明する照明部102と、撮影画像からすり板402,403の摩耗量を計測する画像処理部104と、を備え、すり板402,403は、線路方向207に並んで複数列に配置され、撮像部101と照明部102は、線路203の側方に当該線路203に対して同じ側に設置され、照明部102は、すり板402,403を上方から照明し、撮像部101は、当該撮像部101と照明部102との間に設定されている撮影領域205内ですり板402,403を上方から撮影するように構成した。【選択図】図3
