To improve measurement efficiency by suppressing consumption of a power source and ensuring longer measurable time when an unmanned flying object flies in order to supply the power source.SOLUTION: The underwater measurement device comprises a three-dimensional measurement unit 16A that is detachably connected to an electromagnet 26 provided to a wire 24 suspended from a remote-controlled unmanned flying object 14 and that performs measurement in the state of being positioned underwater, and moors, when it is determined that a battery capacity for flying the unmanned flying object 14 is equal to or smaller than a prescribed threshold value, the three-dimensional measurement unit 16A, and releases connection between the electromagnet 26 and the three-dimensional measurement unit 16A. Then, the unmanned flying object 14 with the three-dimensional measurement unit 16A removed flies to a power supply device to supply the power to the battery, and when power supplying to the battery is completed, the unmanned flying object 14 flies to the three-dimensional measurement unit 16A and returns. Then, the electromagnet 26 and the three-dimensional measurement unit 16A are connected again, the mooring of the three-dimensional measurement unit 16A is released, and the measurement is resumed.SELECTED DRAWING: Figure 2

    【課題】動力源を供給するために無人飛行体を飛行させる際の動力源の消費を抑制し、測定可能な時間をより長く確保して測定効率の向上を図る。【解決手段】遠隔制御される無人飛行体14に吊り下げられたワイヤ24に設けられた電磁石26に取り外し可能に連結され、水中に位置した状態で測定する3次元形状測定部16Aを備え、無人飛行体14を飛行させるバッテリの容量が所定の閾値以下であると判断された場合3次元形状測定部16Aを係留し、電磁石26と3次元形状測定部16Aの連結を解除する。そして、3次元形状測定部16Aが取り外された無人飛行体16を電力供給装置まで飛行させてバッテリに電力を供給し、バッテリへの電力の供給が完了した場合、無人飛行体14を3次元形状測定部16Aまで飛行させて戻る。そして、電磁石26と3次元形状測定部16Aを再度連結し、3次元形状測定部16Aの係留を解除し、測定を再開可能にする。【選択図】図2
