摘　　要：水利工程中很多水库、堤防工程存在大量水下隐蔽构筑物,潜水员进行巡视时受作业风险等影响,较难开展定期巡视,频次难以保证,不利于水库的安全运维工作。为此提出一种基于ROV平台的水下精细探测技术,利用搭载于ROV平台上的三维图像声呐获取观测物体的三维点云数据,利用光学成像系统获取观测物体的外观情况等数据,可提供丰富的定性定量信息。某水库拦污栅检测结果表明:该方法能发现水下隐蔽构筑物的破损情况,并对各种污物进行详细描述,在数字孪生流域数据底板建设工作中具有良好的推广前景。There are a large number of underwater hidden structures in reservoirs and embankment project.Due to operational risks,it is difficult to carry out divers’regular inspections,and ensure the number of patrols,which is not conducive to the safe operation and maintenance of reservoirs.In this paper,an underwater fine detection technology based on ROV platform is proposed,which uses the three-dimensional image sonar mounted on the ROV platform to obtain the three-dimensional point cloud data of the observed object,and uses the optical imaging system to obtain the appearance of the observed object,which can provide rich qualitative and quantitative information.The results of the detection of a reservoir sewage barrier show that the proposed method can find the damage of underwater hidden structures,and can describe various pollutants in detail,which has a good prospect for the construction of data base in digital twin watersheds.
