| description | PROBLEM TO BE SOLVED: To provide an inspection image creation device that can obtain a shot image of a railway vehicle traveling on a rail with high resolving power and without an irregular distortion for the purpose of appearance inspection.SOLUTION: The present inspection image creation device comprises: line scan type imaging means (12) that scans railway vehicles moving on rail roads in a vertical direction to obtain shot images; a reference instrument (17) that has a display face having a reference position in the vertical direction indicated, and is fixed to the rail road at a position overlapping a shooting position of the imaging means; and distortion correction means that corrects a shape distortion of the shot image arising from a vertical motion of the railway vehicle. The distortion correction means has: rail distortion correction means that displaces the shot image in the vertical direction for each part so that a line indicative of the reference position successively reflected in the shot images becomes linear; and vehicle body distortion correction means that excludes an image of an area in which a carriage of the railway vehicle and the rail of the shot image are shot, and displaces an image of an area in which the vehicle body of the railway vehicle and accessories fixedly connected to the vehicle body are shot in the vertical direction for each part.SELECTED DRAWING: Figure 1
【課題】外観検査用に、不規則な歪みがなく、高い分割能で、レール上を走行する鉄道車両の撮影画像を得ることのできる検査用画像生成装置を提供する。【解決手段】この検査用画像生成装置は、線路上を移動する鉄道車両を上下方向に走査して撮影画像を得るラインスキャン型の撮影手段（１２）と、上下方向の基準位置が示された表示面を有し且つ撮影手段の撮影箇所と重なる位置で線路に固定された基準器（１７）と、鉄道車両の上下動に起因する前記撮影画像の形状の歪みを補正する歪み補正手段とを備え、歪み補正手段は、撮影画像に連続的に写り込んだ基準位置を示す線が直線状になるように撮影画像を部分毎に上下方向にずらすレール歪み補正手段と、撮影画像のうち、鉄道車両の台車およびレールが写される領域の画像を除いて、鉄道車両の車体および車体に固定的に接続された付属物が写される領域の画像を部分毎に上下方向にずらす車体歪み補正手段とを有する。【選択図】図１ |
