BRIDGE INSPECTION SYSTEM AND BRIDGE INSPECTION METHOD
PROBLEM TO BE SOLVED: To provide a bridge inspection system and a bridge inspection method capable of realizing a high-precision bridge inspection in a manner that simultaneously obtains a relation between damage on an upper face of a bridge and other damage on a lower face thereof by using an accurate position of the damage.SOLUTION: A bridge inspection system comprises: a first measuring device installed above an upper face of a bridge; a second measuring device installed below a lower face thereof; a flight vehicle which is mounted on an imaging device and moves along the lower face of the bridge; a power source device which is connected to the flight vehicle through a cable and supplies the same with electric power; a control device of the flight vehicle; and an operation processing device which carries out a calculation of coordinates of an inspection object section on the upper face of the bridge and the flight vehicle. The operation processing device calculates: the coordinates of the inspection object section on the basis of a measurement value of the first measuring device with a position where the first measuring device is installed as a coordinate reference; and the coordinates of the flight vehicle on the basis of the measurement value of the second measuring device. The control device outputs a movement instruction signal on the basis of a difference between a coordinate value of the flight vehicle and the same of the inspection object section. The flight vehicle moves in accordance with the movement instruction signal and takes an image of the lower face of the bridge immediately below the inspection object section.SELECTED DRAWING: Figure 1
【課題】橋梁上面と橋梁下面の損傷の関係を同時に正確な位置で把握し、高精度な橋梁点検の実現を可能とする橋梁点検システム及び橋梁点検方法を提供する。【解決手段】橋梁上面の上側に設けられた第一計測装置と、下側に設けられた第二計測装置と、撮像装置を搭載し橋梁下面に沿って移動する飛行体と、飛行体とケーブル接続され飛行体に電力を供給する電源装置と、飛行体の制御装置と、橋梁上面の点検対象部及び飛行体の座標を算出する演算処理装置を有する。演算処理装置は、第一計測装置が設置された位置を座標基準とし、点検対象部の座標を第一計測装置の計測値に基づいて算出し、飛行体の座標を第二計測装置の計測値に基づいて算出する。制御装置は、飛行体の座標の値と点検対象部の座標の値の差分に基づく移動指示信号を飛行体に出力し、飛行体は、移動指示信号に基づき移動し、橋梁下面における点検対象部の真下の画像を取得する。【選択図】 図１
