The Application of Underwater Fine Detection Technology Based on ROV Platform in the Safety Detection of Underwater Concealed Structures
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.
