To make it possible to stably image and inspect the same position on a shaking object.SOLUTION: An inspection apparatus includes: a drone 12 that flies about a blade 6 of a shaking ocean windmill 1; a stationary camera 13 and gimbal camera 14 mounted in the drone 12; and a drone/gimbal camera motion control unit that is incorporated in the drone 12 and controls the motion of at least one of the drone 12 and gimbal camera 14 so that the drone or gimbal camera follows a displacement derived from a shake of the blade 6 detected based on images of the blade 6 taken by the stationary camera 13 and gimbal camera 14.SELECTED DRAWING: Figure 2 【課題】動揺する対象物の同一位置を安定して撮影し点検することができること。【解決手段】動揺する洋上風車１のブレード６の周囲を飛行するドローン１２と、ドローン１２に設置される固定カメラ１３、ジンバルカメラ１４と、固定カメラ１３、ジンバルカメラ１４にて撮影されたブレード６の画像に基づいて検出されたブレード６の動揺に起因する変位に追従するように、ドローン１２及びジンバルカメラ１４の少なくとも一方の動作を制御すると共に、ドローン１２に設けられたドローン・ジンバルカメラ動作制御部と、を有して構成されたものである。【選択図】図２
