UNDER BRIDGE INSPECTION SYSTEM
To provide an under bridge inspection system capable of acquiring an image required for an inspection of a structure while stably grasping an accurate self position of a flight vehicle mounting imaging means using a laser sensor under a bridge where an interval of piers is large.SOLUTION: An under bridge inspection system includes a flight vehicle 1 mounted with a movement information collection apparatus that grasps a traveling direction and a velocity and a distance measurement apparatus that measures a distance to a detection target by a laser. The distance measurement apparatus is disposed above the flight vehicle 1. An emission point where the distance measurement apparatus emits the laser at a predetermined time interval to a range of a predetermined irradiation angle A moves in an entire area of a circumferential direction with an axial line inclining to a vertical axis G as a rotation axis S while emitting the laser.SELECTED DRAWING: Figure 1
【課題】橋脚の間隔距離が大きい橋梁の下側で、撮像手段の搭載された飛行体の正確な自己位置を、レーザセンサを用いて安定して把握し続けながら、構造物の点検に必要な画像を得ることを可能とする橋梁下点検システムを提供する。【解決手段】進行方向と速度を把握する移動情報収集装置と検出対象物に対する距離をレーザで測定する距離測定装置が搭載された飛行体１を備える。前記距離測定装置は飛行体１本体の上部に配置され、前記距離測定装置において所定の照射角Ａの範囲に所定の時間間隔で前記レーザを射出する射出点が、鉛直軸Ｇに対し傾倒した軸線を回転軸Ｓとし周方向の全域を、前記レーザを射出しながら移動する。【選択図】図１
