PROBLEM TO BE SOLVED: To provide an underwater position measuring device and method capable of precisely measuring the position of a benthic-installed object such as a transmarine cable and grasping the state such as the presence of damage.SOLUTION: A camera 4 is provided on a traveling body 2 having a pair of crawlers 3 arranged at intervals in the width direction of the traveling body and traveling in a self-supporting state on the water bottom B, and the traveling body 2 and a GPS device 8 mounted in a floating body 7 floating over the water surface are connected with a cord-like body 6. While, using a tension control mechanism 9 of the cord-like body 6, suppressing the lowering of ground contact pressure of the traveling body 2 and keeping the tension of the cord-like body 6 to a predetermined range so as to bring the floating body 7 closer to just above the traveling body 2, the image data of the benthic-installed object T is acquired by the camera 4 and the position data by the GPS device 8 at that time is acquired.SELECTED DRAWING: Figure 1
【課題】海底ケーブル等の水底設置物の位置を精度よく測位できるとともに、損傷の有無などの状態を把握することができる水中位置測位装置および方法を提供する。【解決手段】車体幅方向に間隔をあけて配置された一対のクローラ3を有して水底Bに自立した状態で走行する走行体2にカメラ4を備え、この走行体2とGPS装置8が設置されて水上に浮かぶ浮体7とを紐状体6により接続する。そして、この紐状体6を張力制御機構9により、走行体2の接地圧の低下を抑制するとともに浮体7を走行体2の真上に近づけるように、紐状体6の張力を予め設定された所定範囲に維持する制御を行ないながら、カメラ4により水底設置物Tの画像データを取得するとともにその際のGPS装置8による位置データを取得する。【選択図】図1
