Title:
水中測定装置
Document Type and Number:
Japanese Patent JP7280799
Kind Code:
B2
Abstract:
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
