UNDERWATER MEASUREMENT METHOD AND UNDERWATER MEASUREMENT SYSTEM
PROBLEM TO BE SOLVED: To improve reproducibility of a shape of a measurement object in an image indicating a three-dimensional shape of the measurement object, under a situation in which an object other than the measurement object is present in the vicinity of the measurement object under the water.SOLUTION: An operator operates a crane 3 disposed on a work barge 2 to install a measurement object 14B (concrete block) that is hung via a measurement object 14A (hanging frame) at a predetermined position under the water. While the operator operates the crane 3, a processing device 12 uses distances to each of a plurality of points on surfaces of the measurement object 14A and the measurement object 14B, which are measured by a sonar 11, to generate an image indicating three-dimensional shapes of these measurement objects, and a display device 13 displays the image. The measurement object 14A and the measurement object 14B each have a sound absorption material at a part of the surface. A breakwater 4 degrades reproducibility of the shapes of the measurement object 14A and the measurement object 14B in the image displayed by the display device 13. However, the degree of degradation of parts that have the sound absorption material is small.SELECTED DRAWING: Figure 1
【課題】水中の被計測物の近傍に被計測物以外の物体がある状況下で被計測物の３次元形状を表す画像における被計測物の形状の再現性を向上する。【解決手段】作業者は作業船２に配置されているクレーン３を操作して被計測物１４Ａ（吊り枠）を介して吊り下げられた被計測物１４Ｂ（コンクリートブロック）を水中の所定位置に据え付ける。作業者がクレーン３を操作する間、処理装置１２はソナー１１により計測される被計測物１４Ａおよび被計測物１４Ｂの表面の複数点の各々までの距離を用いてそれらの３次元形状を表す画像を生成し、表示装置１３は当該画像を表示する。被計測物１４Ａおよび被計測物１４Ｂは表面の一部に吸音材を有する。防波堤４は表示装置１３が表示する画像における被計測物１４Ａおよび被計測物１４Ｂの形状の再現性を低下させるが、防音材を有する部分に関しては再現性の低下が少ない。【選択図】図１
