BRIDGE INSPECTION SUPPORT SYSTEM AND BRIDGE INSPECTION SUPPORT METHOD
PROBLEM TO BE SOLVED: To enable effective road maintenance, by simply confirming a damage state of an undersurface of a bridge.SOLUTION: A photographing device of turning at least in the just above direction, obliquely upward backward and obliquely downward forward, provides an expansion image by a bridge inspection support method of including a travel step of traveling on a road under a bridge by a travel vehicle having the photographing device for setting a restrictor valve to a maximum value, at least a photographing step of acquiring a plurality of photographing images of an undersurface of the bridge by returning the restrictor value to a maximum in the timing of finishing photographing, by opening the restrictor value to a designation value in the timing of starting the photographing, by photographing the undersurface of the bridge from the respective photographing devices over just after from just before the vehicle passes through under the bridge and an image correction step of generating the expansion image of the undersurface of the bridge by correcting a plurality of acquired photographing images.SELECTED DRAWING: Figure 3
【課題】橋梁の下面の損傷状態を簡単に確認できるようにし、効果的な道路保守ができるようにする。【解決手段】少なくとも、真上方向、斜め上後方、および、斜め下前方を向く撮影装置であって、絞り値が最大値に設定される撮影装置を具備する走行車両で橋梁の下方の道路を走行する走行ステップと、少なくとも、車両が橋梁下を通過する直前にから直後にかけて、各撮影装置から橋梁の下面を撮影し、撮影開始のタイミングで絞り値を指定値に開放し、撮影終了のタイミングで絞り値を最大に戻し、橋梁の下面の複数の撮影画像を取得する撮影ステップと得られた複数の撮影画像を補正し、橋梁の下面の展開画像を生成する画像補正ステップと、を含む橋梁検査支援方法によって展開画像を提供する。【選択図】図３
