To provide a novel technique that can identify which position of a structure was struck by lightning, as compared to the conventional technique that can only identify which structure was struck by lightning.SOLUTION: A lightning-struck position identifying device 10 as an information processing device comprises a control unit 11. In the control unit 11, an image acquisition unit 101 acquires a thermal image showing temperature distribution of a blade 701 in a wind power generator 70 captured with a camera device 30. When the wind power generator 70 is struck by lightning, a position identifying unit 105 identifies a position of the blade 701 that has been struck by lightning, as a lightning-struck position, on the basis of the temperature distribution shown by the thermal image.SELECTED DRAWING: Figure 4 【課題】被雷した構造物の特定のみを行う従来技術に対し、被雷した構造物のどの位置に雷撃を受けたかを特定する。【解決手段】情報処理装置としての被雷位置特定装置１０は、制御部１１を備え、制御部１１では、画像取得部１０１が、カメラ装置３０により撮影された風力発電装置７０のブレード７０１の温度分布を示す熱画像を取得する。位置特定部１０５は、風力発電装置７０が被雷した際に、熱画像により示される温度分布に基づいて、ブレード７０１上の雷撃を受けた位置を被雷位置として特定する。【選択図】図４
