UNDERWATER WORK SUPPORT METHOD AND UNDERWATER WORK SUPPORT SYSTEM
To provide means for improving the efficiency of underwater work by providing the three-dimensional shape of a target in a work region with required accuracy in real time regardless of the magnitude of water depth in the work region.SOLUTION: A sound wave transmitting/receiving unit 111 of a three-dimensional sonar system 11, which measures the three-dimensional shape of a target 5 underwater by the transmission of a sound wave once, is hung underwater by a hanging rope 131. The three-dimensional sonar system 11 measures the three-dimensional shape of the target 5 with high accuracy on the basis of sound waves transmitted and received by the sound wave transmitting/receiving unit 111 that is disposed near the target 5. An acoustic positioning system 12 and an inertial navigation device 17 identify the position of the sound wave transmitting/receiving unit 111. An operator performs underwater work using an underwater work device 151 while checking the three-dimensional shape measured by the three-dimensional sonar system 11.SELECTED DRAWING: Figure 1
【課題】作業領域の水深の大小にかかわらず、作業領域内の対象物の３次元形状を必要な精度でリアルタイムに提供することによって、水中作業の効率を高める手段を提供する。【解決手段】水中の対象物５の３次元形状を１回の音波の送波により計測する３次元ソナーシステム１１の送受波ユニット１１１を吊り索１３１で水中に吊る。３次元ソナーシステム１１は、対象物５に近い位置に配置される送受波ユニット１１１により送受波する音波に基づき、対象物５の３次元形状を高い精度で計測する。音響測位システム１２と慣性航法装置１７は、送受波ユニット１１１の位置を特定する。作業者は、３次元ソナーシステム１１により計測される３次元形状を見ながら、水中作業用装置１５１を用いた水中作業を行う。【選択図】図１
