PROBLEM TO BE SOLVED: To measure a degree of degradation of a railway light emitting machine due to stain or aging of a light source, a cover, or the like of the railway light emitting machine.SOLUTION: A railway light emitting machine is made to illuminate at a plurality of levels, which are imaged with a video camera, to obtain brightness of a light emitting machine which is an object of inspection. The obtained brightness and a corresponding brightness at a plurality of levels obtained at the start of operation in advance are corrected with a brightness of a peripheral image, for comparison thereafter, to determine a degree of degradation of the railway light emitting machine.SELECTED DRAWING: Figure 3

    【課題】鉄道用発光機の光源やカバー等の汚れあるいは経年劣化等により鉄道用発光機がどの程度劣化したかを測定する。【解決手段】 鉄道用発光機を複数レベルで発光させ、これをビデオカメラで撮影して検査対象発光機の輝度を得る。得られた輝度と、あらかじめ運用開始時に得られていた対応する複数レベルの輝度とを周囲画像の輝度で補正した上で比較して、鉄道用発光機の劣化の程度を判定する。【選択図】図3
