To prevent an unmanned aerial vehicle from crashing.SOLUTION: In a submersible measuring device, a three-dimensional shape measuring part 24 is positioned underwater in order to measure a three-dimensional shape of a water bottom 46 and to generate three-dimensional shape information, and a water bottom shape information generating part 12F generates the shape of the water bottom 46 as water bottom shape information to be indicated at a coordinate position on the earth, on the basis of the three-dimensional shape information and the measured information. A floating body 32 for adding buoyance to a housing 22 accommodating the three-dimensional shape measuring part 24 is provided, and buoyance of the floating body 32 is controlled. Further, if the capacity of a battery B being a power source of an unmanned aerial vehicle 14 is equal to or less than a prescribed threshold, buoyance is added to the floating body 32 so that a submersible part 16 is moved to the water surface, in order to make the unmanned aerial vehicle 14 land on a landing surface that is an upper surface of the housing 22.SELECTED DRAWING: Figure 5
【課題】無人飛行体の墜落を防止する。【解決手段】3次元形状測定部24を水中に位置させて水底46の3次元形状を測定し3次元形状情報を生成すると共に、3次元形状情報および測位情報に基づいて水底形状情報生成部12Fにより水底46の形状を地球上の座標位置で示される水底形状情報として生成する。3次元形状測定部24を収容する筐体22に浮力を与える浮体32を設けると共に、浮体32の浮力を制御する。そして、無人飛行体14の動力源であるバッテリBの容量が所定の閾値以下である場合、浮体32に浮力を与えて水中部16を水面に移動させ、筐体22の上面である着地面に無人飛行体14を着地させる。【選択図】図5
