To provide a water bottom shape measuring apparatus that is useful for simplifying a configuration while suppressing cost.SOLUTION: A three-dimensional shape measuring part 14E suspended from an unmanned flight body 14 through a support member 20 is positioned in the water, a three-dimensional shape of a water bottom 22 is measured and three-dimensional shape information is generated. A position of the unmanned flight body 14 is measured by a positioning part 14D and the position is generated as positioning information, and a shape of the water bottom 22 is generated by a water bottom shape information generation part 12F on the basis of the three-dimensional shape information and the positioning information as water bottom shape information indicated by a coordinate position on the earth. Until the unmanned flight body 14 moves to a predetermined target position from a movement start position, gas having smaller specific gravity than air is sealed in a balloon 30 connected to the three-dimensional shape measuring part 14E, and when the unmanned flight body 14 moves to the target position, the gas is discharged from the balloon 30.SELECTED DRAWING: Figure 2

    【課題】コストを抑制しつつ構成の簡素化を図る上で有利な水底形状測定装置を提供する。【解決手段】無人飛行体14に支持部材20を介して吊り下げた3次元形状測定部14Eを水中に位置させて水底22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、測位部14Dにより無人飛行体14の位置を測位し測位情報として生成し、それら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22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。無人飛行体14が移動開始地点から所定の目標地点に移動するまでは、3次元形状測定部14Eに接続されたバルーン30内に空気より比重が小さいガスを封入した状態とし、無人飛行体14が目標地点に移動するとバルーン30からガスを排出させるようにした。【選択図】図2
