To provide a water bottom shape measuring device which can efficiently generate water bottom shape information.SOLUTION: A water bottom shape measuring device is configured to measure a three-dimensional shape of a water bottom 46 by positioning a three-dimensional shape measuring part 24 for generating three-dimensional shape information, and generate by a water bottom shape information generation part 12F, a shape of the water bottom 46 as water bottom shape information indicated by a coordinate position on the earth, on the basis of the three-dimensional shape information and positioning information. A housing 22 storing the three-dimensional shape measuring part 24 has a floating body 32 applying buoyancy, and buoyancy of the floating body 32 is controlled. Upon floating an underwater part 16A including the housing 22 on a water level 48 by an unmanned flight body 14 and moving the underwater part along the water level 48, by reducing the weight of the housing 22 applied to the unmanned flight body 14 by the buoyancy of the floating body 32, a load applied to the unmanned flight body 14 can be reduced compared to a case where the underwater part 16A including the housing 22 is moved in a state of being positioned in the air by the unmanned flight body 14.SELECTED DRAWING: Figure 3

    【課題】水底形状情報の生成を効率よく行なう上で有利な水底形状測定装置を提供する。【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。無人飛行体14によって筐体22を含む水中部16Aを水面48に浮かべて水面48に沿って移動させるにあたって、浮体32の浮力の分だけ無人飛行体14に加わる筐体22の重量を軽減するようにすれば、無人飛行体14によって筐体22を含む水中部16Aを空中に位置させた状態で移動させる場合に比較して無人飛行体14の負荷を軽減させることができる。【選択図】図3
